What's new in Nvidia Linux Display Driver 32-bit 390.129

Jul 29, 2019
  • Improved nvidia-bug-report.sh to grab the output of the `vulkaninfo` command when it is available.
  • Updated nvidia-bug-report.sh to search the systemd journal for gdm-x-session logs.
  • Added support to nvidia-installer for systems which provide ncurses libraries supporting the ncurses widechar ABI only.
  • Updated nvidia-installer to avoid problems with commands whose proper functionality may be dependent on system localization (e.g. via the LANG environment variable.) For example, some kernel configurations may produce unusable kernel modules if LANG is set to a language other than English.
  • Updated nvidia-installer for better compatibility with ncurses when libncurses.so.6 exposes the ncurses reentrant ABI, such as on openSUSE Leap 15 and SUSE Linux Enterprise 15.

New in Nvidia Linux Display Driver 32-bit 390.87 (Sep 7, 2018)

  • Improved nvidia-bug-report.sh to check for kern.log which is the default kernel log-file location for many Debian-based Linux distributions.
  • Fixed a bug which could cause X servers that export a Video Driver ABI earlier than 0.8 to crash when running X11 applications which call XRenderAddTraps().

New in Nvidia Linux Display Driver 32-bit 390.59 (May 16, 2018)

  • Added support for the following GPUs:
  • GeForce GTX 1050 with Max-Q Design
  • Quadro P3200
  • Quadro P4200
  • Added support for X.Org xserver ABI 24 (xorg-server 1.20).

  • Fixed a bug which could cause X servers that export a Video Driver ABI earlier than 0.8 to crash when running X11 applications which call XRenderAddTraps().

New in Nvidia Linux Display Driver 32-bit 390.42 (Mar 12, 2018)

  • Fixed a regression, introduced in 390.12, that caused occasional flicker when using the X driver's composition pipeline, for example when using screen transformations like rotation, or the "ForceCompositionPipeline" or "ForceFullCompositionPipeline" options."

New in Nvidia Linux Display Driver 32-bit 387.34 (Dec 29, 2017)

  • Added support for the following GPU:
  • TITAN V
  • GTX 1070 Ti
  • Fixed a bug that caused Vulkan X11 swapchains to fail on GPUs without a display engine, such as some Tesla-branded graphics cards and some Optimus laptops.
  • Fixed a bug that caused fullscreen Vulkan applications to hang on some
  • Kepler GPUs, such as the GeForce GTX 680.
  • Fixed a bug where the G-SYNC indicator was reporting "normal" instead
  • of "G-SYNC" on Vulkan applications when G-SYNC was enabled.

New in Nvidia Linux Display Driver 32-bit 387.22 (Oct 31, 2017)

  • Added support for the following GPU:
  • GTX 1070Ti
  • Fixed a regression that could cause driver errors when setting modes that include DisplayPort Multi-Stream Transport devices.
  • Added an nvidia.ko kernel module parameter, NVreg_EnableBacklightHandler, which can be used to enable experimental handling of laptop backlight brightness through /sys/class/backlight/. This handler overrides the ACPI-based one provided by the video.ko kernel module.
  • NVreg_EnableBacklightHandler is disabled by default.
  • Added G-SYNC to all supported Vulkan swapchains for Maxwell and up. G-SYNC is enabled by default when using G-SYNC-ready monitors. For direct-to-display swapchains, an application profile with "GLGSYNCAllowed" setting set to 'false' can be used to disable this feature:
  • { "rules" : [
  • { "pattern" : [], "profile" : [ "GLGSYNCAllowed", false ] }
  • Fixed a regression that caused some display connectors on some GPUs to not report a connected HDMI or DisplayPort audio device even if the connected monitor supports audio.
  • Fixed a bug that sometimes prevented the "Reset Default Configuration" button in the nvidia-settings "ECC Settings" page from being available when the ECC configuration is set to a non-default state.
  • Fixed a bug that caused nvidia-settings to enforce overly aggressive limits on display positions in the "X Server Display Configuration" page under some circumstances.
  • Fixed a bug that could cause the "Enable Base Mosaic (Surround)" checkbox in nvidia-settings to disappear when an X screen, rather than a display, is selected in the "X Server Display Configuration" page.
  • Fixed a race condition that could lead to crashes when OpenGL programs manipulated vertex buffer objects from multiple threads simultaneously.
  • Fixed a bug that caused the nvidia-settings control panel to retain some settings that had been applied, but not confirmed. This resulted in unwanted settings being applied to subsequent settings changes.
  • Improved performance of fullscreen Vulkan applications using X11 swapchains. This optimization will cause more events that trigger an out-of-date swapchain, such as when entering or leaving fullscreen mode. (This is commonly encountered when using the alt-tab key combination, for example.) Applications that do not properly respond to the VK_ERROR_OUT_OF_DATE_KHR return code may not function properly when these events occur. See section 30.8 of the Vulkan specification.
  • Added support for YUV 4:2:0 compression for monitors connected via DisplayPort in configurations where either the display or GPU is incapable of driving the current mode in RGB 4:4:4. See the description in the "Programming Modes" appendix for details.
  • Added framebuffer console hot plug handling to nvidia-modeset.
  • Note that hot plugging is only handled when nvidia-modeset is initialized; for example, when Xorg or nvidia-persistenced is running or when nvidia-drm is loaded with the "modeset=1" parameter.
  • Added an "AllowGSYNC" MetaMode attribute that can be used to disable G-SYNC completely. This can be use to allow enabling features that are incompatible with G-SYNC, such as Ultra Low Motion Blur or Frame Lock.
  • Fixed several problems that prevented the "cc_version_check" sanity test from running correctly when building the NVIDIA kernel modules. As these problems would have masked mismatches between the compiler versions used to build the kernel and the NVIDIA kernel modules for an extended period of time, nvidia-installer has been updated to ignore CC version mismatches by default when they are detected.
  • Updated nvidia-installer to use the init_module syscall directly to test load kernel modules instead of libkmod/insmod. This removes libkmod as a build dependency of nvidia-installer, and insmod as a run-time dependency.
  • Tiled monitors formerly resulted in a separate Xinerama screen being reported for each tile. They will now, by default, be combined into a single large Xinerama screen.
  • The individual panels in a tiled monitor will now be arranged based on the layout information provided in the monitor's EDID. This can be overridden by either manually specifying offsets or using the "MetaModeOrientation" option.
  • Disabled interlaced modes over DisplayPort by default due to incomplete support in the GPU. Added "AllowDpInterlaced" mode validation token to override this default behavior and allow interlaced modes over DisplayPort protocol anyway.
  • Fixed a bug that could cause some eDP G-SYNC displays to flicker at low refresh rates.
  • Fixed a bug that could cause OpenGL applications to crash after a prolonged DPMS sleep state on a monitor driven with PRIME Sync.
  • Fixed a bug that artificially limited the maximum pixel clock to 300 MHz when using certain more capable DisplayPort to HDMI adapters.
  • Fixed a bug that prevented the NVIDIA kernel modules from building for non-SMP Linux kernels.
  • Updated the output of `nvidia-smi nvlink --status` to include reporting NVLink speed.
  • Fixed a bug that caused incorrect PCI topology reporting in nvidia-smi on Intel Skylake systems.

  • Fixed a bug that caused S4 suspend (also known as "hibernate") to hang during suspend when SLI was enabled.
  • Fixed a bug where devices would not be properly enumerated by the Vulkan driver. See the "Known Issues" section of the README for more details.
  • Fixed a bug that could cause OpenGL applications to crash after calling glDeleteBuffers on VBOs that have been remapped with ARB_vertex_attrib_binding.
  • Fixed a bug that could sometimes cause OpenGL applications to lock up until the X server receives input.
  • Fixed a bug that caused nvidia-settings to drop device BusID values when making changes to an existing X configuration file.
  • Fixed a regression that prevented nvidia-xconfig from querying some GPUs, e.g. when running `nvidia-xconfig -a`.
  • Fixed a bug that caused VDPAU playback to be corrupted when extended to coordinates beyond 16384 pixels.
  • Updated nvidia-persistenced to initialize nvidia-modeset.ko in addition to nvidia.ko when setting persistence mode.
  • Restored several sanity checks that were inadvertently removed from the kernel module build process in the 355.06 driver.
  • Added support for a "Nearest" transform filter in the X driver. This causes the X driver to use nearest neighbor filtering when performing screen transformations. The filter can be requested through the 'filter' argument to RandR's RRSetCrtcTransform, or through the 'ResamplingMethod' MetaMode token.
  • Fixed a bug where nvidia-installer would install a wrong version of the Vulkan ICD configuration file when GLVND is disabled for the GLX client.
  • Fix a bug with GLX_EXT_buffer_age where incorrect buffer age values would be reported for SLI AFR configurations. In such configurations buffer age may now be greater than 3, the previous maximum buffer age.
  • Fixed a bug that could cause hanging and Xids when performing RandR transforms with Overlay and SLI enabled.
  • Extended the information reported by the NVIDIA Xinerama X extension to report PRIME displays in addition to directly-connected displays.
  • Fixed a bug that caused HDMI audio devices to appear or disappear inconsistently when HDMI devices were hotplugged or unplugged.
  • Fixed a bug that could cause driver errors when setting modes on X screens running at Depth 8 or Depth 15.
  • Fixed a bug that could cause intermittent kernel panics when running with PRIME Sync.
  • Fixed a bug that caused a kernel panic when hotplugging HDMI displays on some Zotac mini PCs.
  • Updated nvidia-installer to label kernel modules with SELinux file type 'modules_object_t'. Some system SELinux policies only permit loading of kernel modules with this SELinux file type.
  • Removed support for checking for and downloading updated driver packages and precompiled kernel interfaces from nvidia-installer. This functionality was limited to unencrypted ftp and http, and was implemented using code that is no longer actively maintained.

New in Nvidia Linux Display Driver 32-bit 381.22 (May 9, 2017)

  • Fixed a bug that caused the GLX_EXT_buffer_age buffer age extension to return incorrect values for stereo drawables when using passive stereo modes 5 through 9.
  • Fixed a bug in Vulkan direct to display where DP1.2 monitors were not being enumerated.
  • Improved compatibility with recent kernels.
  • Fixed a bug that caused "nvidia-settings --query all" to print many duplicate entries.
  • Fixed a bug that caused applications to crash in some situations when calling glXMakeCurrent while OpenGL threaded optimizations were enabled. This frequently occurred when Steam was attempting to make a video appear full-screen.
  • Fixed a bug that caused VDPAU applications to use the blit presentation queue when a previous VDPAU application didn't shut down cleanly.
  • Fixed hangs and crashes that could occur when an OpenGL context is created while the system is out of available memory.
  • Fixed a bug that caused corruption when OpenGL windows were moved or resized.
  • Fixed a bug that caused X screens that use Option "UseDisplayDevice" "none" to be resized to 640x480 when using "xrandr -s" to change the screen configuration.
  • Fixed a kernel crash that occurred when attempting to map large user memory allocations into CUDA.
  • Disabled OpenGL threaded optimizations by default, initially enabled in 378.09, due to various reports of instability.
  • Added support for the following Vulkan extensions:
  • VK_EXT_acquire_xlib_display
  • VK_EXT_display_control
  • VK_EXT_display_surface_counter
  • VK_EXT_direct_mode_display
  • VK_KHX_external_memory
  • VK_KHX_external_memory_fd
  • VK_KHX_external_semaphore
  • VK_KHX_external_semaphore_fd
  • These extensions require a Vulkan loader version >= 1.0.42.
  • Removed the X driver's logo splash screen and the corresponding NoLogoand LogoPath xorg.conf options.
  • Added the "ResamplingMethod" MetaMode option, adding support for bicubic resampling methods when scaling screen transformations are in use. See the README for more details.

New in Nvidia Linux Display Driver 32-bit 375.66 (May 4, 2017)

  • Added support for the following GPUs:

  • TITAN Xp
  • Fixed a bug that could cause EGL applications to crash when calling eglInitialize() multiple times on X11-backed displays.
  • Fixed a regression that could cause rendering corruption on a monitor connected via DisplayPort upon a modeset event (for example, changing resolutions or power cycling the monitor).
  • Updated the display configuration page in the nvidia-settings control panel to accurately reflect HDMI 3D refresh rates.
  • Fixed a bug that could cause OpenGL applications to crash when VT switching between multiple X servers.
  • Fixed a bug that caused the system to become unresponsive after resuming from power management suspend/hibernate. Additional symptoms of this bug included display flickering and "Xid 56" errors in the kernel log.
  • Fixed a bug that caused backlight brightness to not be controllable on some notebooks with DisplayPort internal panels.
  • Fixed a bug that left HDMI and DisplayPort audio muted after a framebuffer console mode was restored. For some displays, this caused the display to remain blank.
  • Fixed a bug that caused audio over DisplayPort to stop working when the monitor was unplugged and plugged back in or awoken from DPMS power-saving mode.
  • Restored support for the following GPU:
  • GRID K520
  • Fixed a regression that caused corruption in certain applications, such as window border shadows in Unity, after resuming from suspend.
  • Installation of the nvidia-drm kernel module is now optional. The new '--no-drm' option can be used to prevent nvidia-installer from building and installing nvidia-drm, on systems where this kernel module fails to build and/or load.
  • Fixed a bug that could cause some applications to crash when running with PRIME Sync.
  • Fixed a bug that prevented PRIME Sync from working on notebooks with GeForce GTX 4xx and 5xx series GPUs.
  • Fixed a bug that caused OpenGL apps to have excessive CPU usage when running with PRIME Sync but without native displays enabled.
  • Fixed a bug that could cause PRIME Sync to deadlock in the kernel, particularly common on Linux 4.10.

  • The driver will now advertise GLX FBConfigs with no depth bits on depth 30 X screens.
  • Added support in nvidia-settings to view configured PRIME displays. To enable PRIME displays, see "Offloading Graphics Display with RandR 1.4" in the README.
  • Added infrastructure which enables the NVIDIA EGL driver to load EGL external platform libraries that add client-side support for new window systems, beyond the existing libnvidia-egl-wayland.so.1. For more details, see:
  • - https://github.com/NVIDIA/eglexternalplatform
  • - https://github.com/NVIDIA/egl-wayland
  • Added support for the following Vulkan extensions:
  • VK_KHR_display
  • VK_KHR_display_swapchain
  • Enabled OpenGL threaded optimizations by default in the driver. Refer to the "Threaded Optimizations" section in the "Specifying OpenGL Environment Variable Settings" chapter of the README for details. These optimizations will self-disable when they are degrading performance. As a result, performance should be unchanged for many applications, and increased for those that benefit from threaded optimizations and were not already forcing them enabled.
  • Fixed a bug that prevented PRIME Sync from working on notebooks with GeForce GTX 4xx and 5xx series GPUs.
  • Fixed a bug that caused system hangs when resuming from suspend with some GPUs.
  • Fixed a regression that could cause corruption when hot-plugging displays.

  • Fixed a regression that prevented the backlight on some notebook computer displays from turning back on after being shut off.
  • Fixed a regression that prevented the console from being restored properly when using SLI.
  • Fixed a bug that caused installer manifest entries for some 32-bit compatibility libraries to be duplicated in the installer package. These entries led nvidia-installer to issue warning messages when installing the 32-bit compatibility libraries, for example: 'Cannot create symlink /usr/lib/libEGL.so (File exists)'.
  • Fixed a regression that could cause the nvidia-settings control panel to crash on startup with certain GPU configurations.
  • Fixed a regression that prevented the GLX_NV_swap_group extension from working when using SLI or Quadro Sync.
  • Fixed a long-standing bug that caused the NVIDIA X driver to not correctly detect AC/battery hotplug events on notebooks.
  • Fixed an interaction problem between the Linux kernel's CONFIG_HARDENED_USERCOPY feature (new in Linux kernel 4.8) and nvidia-drm.ko with modeset=1 enabled. This problem caused CONFIG_HARDENED_USERCOPY to erroneously halt the system, issuing reports of the form:
  • usercopy: kernel memory overwrite attempt detected to ffff8803e8ec7ce0 () (8 bytes)
  • Fixed a bug that prevented nvidia-bug-report.sh from finding relevant messages in kernel log files.
  • Added support for the screen_info.ext_lfb_base field, on kernels that have it, in order to properly handle UEFI framebuffer consoles with physical addresses above 4GB.

  • Added EGL support to the GL Vendor Neutral Dispatch Library (libGLVND). The installer package now includes both GLVND and non-GLVND versions of the EGL libraries: the --glvnd-egl-client and --no-glvnd-egl-client options in nvidia-installer can be used to select which to install.
  • Fixed a bug that prevented G-SYNC from working on notebook displays.
  • Fixed a bug that caused DisplayPort multistream devices to go blank after the console is restored.
  • Fixed a bug that caused a kernel crash when starting X for the second time when more than one DisplayPort multistream device is connected to a single DisplayPort connector via a branch device.
  • Updated nvidia-settings to not have a build-time dependence on an external nvml development package (a regression introduced in 375.10).
  • Fixed a crash in nvidia-settings when adding Application Profile Rule and Profile entries.
  • Removed the "Enable Tooltip" option in nvidia-settings for the GTK 2 interface.
  • Added new X configuration options:
  • ForceCompositionPipeline
  • ForceFullCompositionPipeline
  • which override the MetaMode tokens with the same names.
  • Fixed a bug that caused issues with panning and cursor constraining when mixing PRIME-driven displays with natively driven displays.
  • Fixed a bug that caused long delays when leaving the VT or disabling a display device while an OpenGL application is running.

  • Fixed undefined symbol references in libnvidia-glcore.so.
  • Fixed a potential hang in Vulkan applications such as vkQuake and DOTA2 that use vkFences for present synchronization.
  • Fixed a bug that caused the driver to not set HDMI YUV 420 4K modes correctly on some TVs, such as the VIZIO D40u-D1.
  • Updated CurrentMetaMode reporting via the NV-CONTROL API to reflect whether ForceCompositionPipeline or ForceFullCompositionPipeline are set in the current MetaMode.
  • Added the ability to over- and under-clock certain GeForce GPUs in the GeForce GTX 1000 series and later. For GPUs that allow it, an offset can be applied to clock values in some clock domains of all performance levels. This clock manipulation is done at the user's own risk. See the README documentation of the "CoolBits" X configuration option for more details.
  • Implemented initial support for PRIME Synchronization to synchronize flipping between an NVIDIA PRIME display source and a separate PRIME display sink. This support is experimental and currently requires a prerelease X.org X server.
  • Fixed a bug that prevented Vulkan applications from presenting from multiple queues to the same X11 swapchain.
  • Added the "PixelShiftMode" MetaMode option, enabling support for 4K and 8K pixel shift displays. See the README for details.

  • Fixed a regression introduced in 367.35 that caused the first modeset of the X server to display blank if the features requested in the X configuration file enabled the X driver's composition pipeline. This would be triggered, e.g., by MetaMode tokens such as ForceCompositionPipeline, ForceFullCompositionPipeline, Rotation, Reflection, and Transform.

New in Nvidia Linux Display Driver 32-bit 367.35 (Jul 15, 2016)

  • Fixed a regression that could cause console corruption when resuming from suspend.

  • Fixed a bug that caused an incorrect offset to be applied when using the full composition pipeline on a display whose image has both a rotation and a ViewportOut offset applied.
  • Fixed a bug that could cause nvidia-settings to crash on some systems when responding to events such as hotplugging DisplayPort devices.
  • Fixed a bug that could cause crashes in OpenGL applications which use glTextureView() with a non-zero minlevel.
  • Enhanced the Display Device information page in nvidia-settings with additional information for DisplayPort devices to reflect attributes which are specific to DisplayPort connections.
  • Fixed a bug which could cause deleted application profiles to appear when editing rules in the nvidia-settings control panel.
  • Fixed a bug that caused hangs when a G-SYNC monitor is unplugged and a non-G-SYNC monitor is connected while G-SYNC is active.
  • Fixed a bug that caused "nvidia-modeset: ERROR: GPU:0: Activating G-SYNC failed" to be printed to the system log if a G-SYNC monitor is connected and stereo is enabled in xorg.conf on a configuration that doesn't support it.
  • Added the NV_robustness_video_memory_purge OpenGL extension, which
  • allows applications to know when a mode switching or power event purged the contents of FBOs and BOs residing in video memory.
  • Fixed a bug that prevented HDMI 2.0 4K monitors from waking up from sleep or hot-replug.
  • Fixed a bug that could lead to a system crash if there was a peer-to-peer mapping still active during CUDA context teardown.

  • Fixed a bug that could cause nvidia-installer's runtime loader test to fail spuriously on some systems.
  • The NVIDIA Unified Virtual Memory kernel module, nvidia-uvm.ko, now has a minimum kernel requirement of Linux 2.6.32. On older kernel versions, nvidia-uvm.ko will be compiled as a stub kernel module which does not provide any functionality.
  • Updated the libglvnd snapshot included in the NVIDIA driver package to libglvnd commit b7d75429677eecc00c3701aaa4deac1304bc51ff. This contains a new revision of the libglvnd ABI. The driver is not compatible with a libglvnd older than commit c5bcda3b848fe52d6ae6ef25c917431c06d62d27.

  • Added a new RandR property, CscMatrix, which specifies a 3x4 color-space conversion matrix.The matrix is applied after the X colormap and before the gamma ramp.This property is available on GF119 and newer GPUs.
  • Improved handling of the X gamma ramp on GF119 and newer GPUs.On these GPUs, the RandR gamma ramp is always 1024 entries and now applies to the cursor and VDPAU or workstation overlays in addition to the X root window.
  • Reworked how the NVIDIA driver registers with the Linux kernel's DRM subsystem for PRIME support.As a result, PRIME support requires Linux kernel version 3.13 or newer (previously, PRIME support required Linux kernel version 3.10 or newer).
  • Improved the interactivity of applications that use a hardware cursor while G-SYNC is active.

  • Added support for the following GPUs:
  • GeForce 920MX
  • GeForce 930MX
  • Quadro M6000 24GB
  • Limited the default concurrency level in nvidia-settings to 32, to avoid hitting the maximum tasks limit on systems with many CPUs.

  • Added initial support for Direct Rendering Manager Kernel Modesetting (DRM KMS). See the DRM KMS section of the README for details.
  • Added a new kernel module, nvidia-drm.ko, which registers as a DRM driver with both PRIME and DRM KMS support.
  • Added support for the following EGL extensions:
  • EGL_EXT_platform_wayland
  • to enable Wayland applications to run on NVIDIA's EGL implementation,
  • EGL_WL_bind_wayland_display
  • to enable Wayland compositors to run on NVIDIA's EGL implementation, and
  • EGL_EXT_device_drm
  • EGL_EXT_output_drm
  • EGL_EXT_stream_consumer_egloutput
  • to enable Mir and Wayland compositors to display their content through EGLDevice, EGLOutput, and EGLstreams.
  • Added a Wayland platform library, libnvidia-egl-wayland.so, to allow Wayland compositors that support EGLDevice, EGLOutput, and EGLstreams to share EGL buffers with Wayland applications.
  • Fixed a bug that could cause incorrect frame rate reporting on Quadro Sync configurations with multiple GPUs.
  • Added support for the Vulkan API version 1.0.
  • Improved X colormap precision from 8 significant bits to 11 on GeForce GPUs. Quadro GPUs already used 11 bits of precision.

  • Improved the interactivity of applications that use a hardware cursor while G-SYNC is active.

New in Nvidia Linux Display Driver 32-bit 361.28 (Feb 10, 2016)

  • Added support for the following GPU: GeForce 945A
  • Added a legacy, non-GLVND libGL.so GLX client library to the NVIDIA Linux driver installer package, and the ability to select between a GLVND or non-GLVND GLX client library at installation time. This allows users to install the legacy non-GLVND GLX client library in order to work around compatibility issues which may arise due to GLX applications which depend upon behaviors of the NVIDIA GLX client driver which are not defined by the Linux OpenGL ABI version 1.0.
  • By default, nvidia-installer will install the legacy, non-GLVND GLX client libraries. The --glvnd-glx-client command line option can be used to override the default, and install the GLVND GLX client libraries instead. Please contact the vendors of any applications that are not compatible with GLVND to ensure that their applications be updated for compatibility with GLVND.
  • The presence of multiple GLX client libraries in the package has implications for repackagers of the NVIDIA driver; see the libGL.so entry in the "Installed Components" chapter of the README for details.
  • The OpenGL Vendor-Neutral Driver (GLVND) infrastructure is now included and supported by the NVIDIA GLX and OpenGL drivers. This should not cause any visible changes in behavior for end users, but some internal driver component libraries have been renamed and/or moved as a result. These changes may affect scripts that rely on the presence of NVIDIA OpenGL driver components other than those specified in the Linux OpenGL ABI version 1.0, maintainers of alternative NVIDIA driver installation packages, and applications which rely on the presence of any non- OpenGL/GLX symbols in the libGL.so.1 library and its dependencies in any way. Please see https://github.com/NVIDIA/libglvnd. For more information on the GLVND project. The Linux OpenGL ABI version 1.0 specification is available at https://www.opengl.org/registry/ABI
  • Updated nvidia-installer to run ldconfig(8) and depmod(8) after uninstalling an existing driver, instead of only running these two commands when installing a new driver.
  • Removed the VDPAU wrapper and trace libraries libvdpau.so.1 and libvdpau_trace.so.1 from the driver package. These libraries may be available via your distribution's package management system, or can be compiled from the sources available at http://people.freedesktop.org/~aplattner/vdpau/. Please see http://freedesktop.org/wiki/Software/VDPAU/ for more information.
  • Fixed a bug in the EGL driver where a mutex was unlocked more than once. This triggers undefined behavior, and in particular, if lock elision is enabled in glibc, may result in a segmentation fault.

New in Nvidia Linux Display Driver 32-bit 358.16 (Nov 21, 2015)

  • Fixed a regression, introduced in 358.09, that caused incorrect rendering of OpenGL stereo applications in combination with Quadro Sync on certain GPUs.
  • Fixed a regression, introduced in 358.09, that caused OpenGL stereo applications to hang when SLI AFR, SFR, or SLIAA modes were enabled.
  • Fixed a regression, introduced in 358.09, that caused the system to hang while launching OpenGL applications when some SLI Mosaic topologies were in use.
  • Fixed a bug that could cause some G-SYNC monitors to flicker on Kepler-based GPUs when running at low frame rates.
  • Fixed a regression that could cause OpenGL or VDPAU applications to hang in Xinerama layouts which include multiple X screens that are driven by the same GPU.
  • Added a fallback to allow GLX to function when UNIX domain socket communication is blocked between NVIDIA client-side GLX and NVIDIA server-side GLX. For example, the default SELinux policy on Fedora 22 prevents the NVIDIA 358.09 GLX driver from working in GDM3:
  • https://bugzilla.redhat.com/show_bug.cgi?id=1271401
  • Fixed a bug that could cause nvidia-installer to crash when installing from a driver package that has had precompiled kernel interfaces added to it (e.g., by using the "--add-this-kernel" option).
  • Fixed a regression from 358.09 that caused G-SYNC monitors configured to use 3D Vision stereo to go blank and report an unsupported signal.
  • Fixed a regression from 358.09 that caused OpenGL applications that failed to negotiate permission to perform glXSwapBuffers via flipping to stop updating the screen. This was triggered on Fedora 22 where the SELinux system policy prevents gnome-shell from communicating with the X server.
  • Now, OpenGL applications that fail to negotiate flipping will fall back to glXSwapBuffers via blitting.
  • See https://bugzilla.redhat.com/show_bug.cgi?id=1271401 for more details.
  • Fixed a regression that reduced OpenGL performance on headless X server configurations.
  • Fixed a memory leak that occurred after destroying a GLXWindow which still has the current context attached to it.
  • Fixed a bug which caused EGL pbuffers to be created with both a front and back buffer, instead of a back buffer only, as is required for EGL.
  • Added a new kernel module, nvidia-modeset.ko. This new driver component works in conjunction with the nvidia.ko kernel module to program the display engine of the GPU.
  • nvidia-modeset.ko does not provide any new user-visible functionality or interfaces to third party applications. However, in a later release, nvidia-modeset.ko will be used as a basis for the modesetting interface provided by the kernel's direct rendering manager (DRM).
  • Reduced flickering and delays when transitioning into or out of G-SYNC mode. As part of this change, monitors that have G-SYNC indicators in their on-screen displays will now always report that they are in G-SYNC mode. The OpenGL G-SYNC visual indicator can be enabled in nvidia-settings to determine when G-SYNC is actually being used.
  • GLX protocol for the following OpenGL extension from OpenGL 3.0 has been promoted from unofficial to ARB approved official status:
  • GL_EXT_draw_buffers2
  • GLX protocol for the following OpenGL 3.0 commands:
  • BindBufferRangeNV
  • BindBufferBaseNV
  • BeginTransformFeedbackNV
  • EndTransformFeedbackNV
  • GetTransformFeedbackVaryingEXT
  • TransformFeedbackVaryingsEXT
  • which are part of the following extensions:
  • GL_NV_transform_feedback
  • GL_EXT_transform_feedback
  • has been promoted from unofficial to ARB approved official status.
  • With the above changes, GLX protocol for OpenGL 3.0 has been promoted from unofficial to ARB approved official status.
  • Added a new system memory allocation mechanism for large allocations in the OpenGL driver. This mechanism allows unmapping the allocation from the process when it is not in use, making more virtual address space available to the application. It is enabled by default on 32 bit OpenGL applications with Linux 3.11+ and glibc 2.19+. Memory allocated this way will consume space in /dev/shm. Setting the environment variable __GL_DevShmPageableAllocations to 2 will disable this feature
  • Added support for OpenGL 4.3.
  • Added support for X.Org xserver ABI 20 (xorg-server 1.18).

  • Fixed a regression that prevented DPMS from working correctly on some DisplayPort displays.
  • Fixed a bug that could prevent X from starting when configured with multiple X screens, some of which scan out to display devices, and some of which do not.
  • Fixed a bug that could cause texture corruption in some OpenGL applications when video memory is exhausted by a combination of simultaneously running graphical and compute workloads.
  • Added support for X.Org xserver ABI 20 (xorg-server 1.18).

  • Fixed a bug that could cause GPU exceptions when using glReadPixels() on the depth or stencil buffers of multisample windows while resizing or moving the windows.
  • Fixed a bug that could cause data from one texture level to overwrite data from the next lowest level, when creating a texture view that did not include the higher of the two levels.
  • Fixed a bug that could cause the nvidia-settings control panel to crash when updating the display layout.
  • Corrected some erroneous reporting of support for GLX extensions: several extensions were being reported as supported for indirect GLX, which were in fact only supported under direct rendering.
  • Added support for the following EGL extensions:
  • EGL_KHR_swap_buffers_with_damage
  • EGL_NV_stream_consumer_gltexture_yuv
  • Replaced the build system for the NVIDIA kernel modules and updated the installer package and nvidia-installer to use the new build system and kernel module source code layout. For more information about the new build system and layout, see the README document at: ftp://download.nvidia.com/XFree86/packaging/linux/new-kbuild-for-355/
  • Added experimental full OpenGL support to EGL.
  • Marked the DeleteUnusedDP12Displays option as deprecated.
  • Version 1.5.0 of the X Resize and Rotate specification added a note that dynamically-created outputs will not be destroyed, so this option is deprecated and will be removed in a future driver release.
  • Added support for VDPAU profiles added in VDPAU 0.9:
  • VDP_DECODER_PROFILE_H264_BASELINE
  • VDP_DECODER_PROFILE_H264_CONSTRAINED_BASELINE
  • VDP_DECODER_PROFILE_H264_EXTENDED
  • VDP_DECODER_PROFILE_H264_PROGRESSIVE_HIGH
  • VDP_DECODER_PROFILE_H264_CONSTRAINED_HIGH
  • Fixed a bug that prevented more than one RandR output from sharing user-added modes.
  • Fixed a bug that caused application-specified swap intervals to be ignored on some screens when using Xinerama.
  • Fixed a bug that caused user-supplied RandR modes with nonsensical combinations of the +HSync, -HSync, +VSync, and -VSync flags to corrupt the mode list.
  • Added support to make an OpenGL 3.0 and above context current without making current to any drawable.

New in Nvidia Linux Display Driver 32-bit 352.41 (Aug 28, 2015)

  • Added support for the following GPUs:
  • GeForce GTX 950
  • Quadro M4000
  • Quadro M5000
  • Fixed a bug that caused VDPAU to only display the top half of a video frame when decoding and displaying H.265/HEVC encoded video streams.
  • Fixed a bug that caused the X server to crash if an OpenGL application tried to allocate a drawable when GPU-accessible memory is exhausted.

New in Nvidia Linux Display Driver 32-bit 352.30 (Jul 28, 2015)

  • Added support for the following GPU:
  • GeForce 910M
  • Fixed a bug that caused poor video post-processing performance in VDPAU when operating on a large number of video streams simultaneously.
  • Fixed a bug that could cause an Xid error when terminating a video playback application using the overlay presentation queue in VDPAU.
  • Updated nvidia-installer to avoid recursing too deeply into kernel source trees under /usr/lib/modules, mirroring an existing restriction on recursion under /lib/modules.
  • Fixed a rare deadlock condition when running applications that use OpenGL in multiple threads on a Quadro GPU.
  • Fixed a kernel memory leak that occurred when looping hardware - accelerated video decoding with VDPAU on Maxwell-based GPUs.
  • Fixed a bug that caused the X server to crash if a RandR 1.4 output provided by a Sink Output provider was selected as the primary output on X.Org xserver 1.17 and higher.
  • Fixed a bug that caused waiting on X Sync Fence objects in OpenGL to hang indefinitely in some cases.
  • Fixed a bug that prevented OpenGL from properly recovering from hardware errors or sync object waits that had timed out.

New in Nvidia Linux Display Driver 32-bit 346.72 (Jun 24, 2015)

  • Added support for the following GPUs:
  • Tesla K40t
  • GeForce 720A
  • GeForce 920A
  • GeForce 930A
  • GeForce 940A
  • GeForce GTX 950A
  • GeForce GTX 980 Ti
  • Fixed a bug in nvidia-settings that caused the application to crash when saving the EDID to a file.
  • Fixed a bug that prevented the "mkprecompiled" utility included in the driver package from reading files correctly.
  • Fixed a bug that could cause an Xid error when terminating a video playback application using the overlay presentation queue in VDPAU.
  • Updated nvidia-installer to avoid recursing too deeply into kernel source trees under /usr/lib/modules, mirroring an existing restriction on recursion under /lib/modules.
  • Updated nvidia-installer to use modprobe(8) when leaving the NVIDIA kernel module loaded after installation, instead of insmod(8) or libkmod. This allows the kernel module to honor any configuration directives that apply to it in /etc/modprobe.d when it is loaded.
  • Fixed a bug that allowed console messages from the Linux kernel to be drawn over the user interface of nvidia-installer.

New in Nvidia Linux Display Driver 32-bit 352.21 (Jun 16, 2015)

  • Added support for the following GPUs:
  • GeForce 720A
  • GeForce 920A
  • GeForce 930A
  • GeForce 940A
  • GeForce GTX 950A
  • GeForce GTX 980 Ti
  • Fixed a bug that caused the Display Configuration page of the nvidia-settings control panel to automatically generate layouts with multiple displays occupying the same position when enabling or disabling Base Mosaic.
  • Updated nvidia-settings to allow the use of the standard Display Configuration page when SLI Mosaic is enabled.
  • Fixed a bug that caused the kernel to report errors when unmapping DMA allocations on kernels with CONFIG_DEBUG_DMA_API enabled.
  • Added GLX Protocol support for the following OpenGL extensions:
  • GL_ARB_copy_buffer
  • GL_ARB_texture_buffer_object
  • Fixed a bug that caused a kernel crash if SLI Mosaic and G-SYNC were used at the same time on a configuration with more display devices connected to one GPU than another.
  • Added the ability to configure the swapping behavior for quad-buffered stereo visuals. The driver can be configured to independently swap each eye as it becomes ready, to wait for both eyes to complete rendering before swapping, or to allow applications to specify which of these two behaviors is preferred by setting the swap interval. This setting can be adjusted in the nvidia-settings control panel, or via the NV-CONTROL API.
  • Fixed a regression which caused the GPU fan status display to disappear from the nvidia-settings control panel.
  • Added reporting of ECC error counts to the nvidia-settings control panel.
  • Fixed a bug that sometimes prevented OpenGL sampler objects from being properly deallocated when destroying OpenGL contexts.
  • Fixed a bug that caused GLX_EXT_framebuffer_sRGB to incorrectly report sRGB support in 30 bit-per-pixel framebuffer configurations.
  • Added support for G-SYNC with sync-to-vblank disabled. This allows applications to use G-SYNC to eliminate tearing for frame rates below the monitor's maximum refresh rate but allow tearing above the maximum refresh rate in order to minimize latency.
  • When G-SYNC is active and sync-to-vblank is enabled, the frame rate is limited to the monitor's maximum refresh rate.
  • GLSL gl_Fog.scale is now +infinity when gl_Fog.end equals gl_Fog.start. Previously, the value 0 was used, but this broke certain applications such as the game XIII running on Wine (Wine bug #37068).
  • Enabled G-SYNC by default when Unified Back Buffer (UBB) is disabled.
  • Updated the NVIDIA GPU driver to avoid using video memory already in use by vesafb.
  • Fixed a bug in nvidia-settings that caused the application to crash when saving the EDID to a file.
  • Fixed a bug that prevented the "mkprecompiled" utility included in the driver package from reading files correctly.
  • Fixed a bug that could cause an Xid error when terminating a video playback application using the overlay presentation queue in VDPAU.
  • Updated nvidia-installer to avoid recursing too deeply into kernel source trees under /usr/lib/modules, mirroring an existing restriction on recursion under /lib/modules.
  • Fixed a rare deadlock condition when running applications that use OpenGL in multiple threads on a Quadro GPU.
  • Fixed a kernel memory leak that occurred when looping hardware- accelerated video decoding with VDPAU on Maxwell-based GPUs.
  • Fixed a bug that caused the X server to crash if a RandR 1.4 output provided by a Sink Output provider was selected as the primary output on X.Org xserver 1.17 and higher.
  • Fixed a bug that caused waiting on X Sync Fence objects in OpenGL to hang indefinitely in some cases.
  • Fixed a bug that prevented OpenGL from properly recovering from hardware errors or sync object waits that had timed out.

New in Nvidia Linux Display Driver 32-bit 346.72 (May 13, 2015)

  • Fixed a bug causing loss of stereo synchronization in certain Quadro Sync framelock configurations.
  • Fixed Pixel Buffer Object operations when row length is less than width. GL_[UN]PACK_ROW_LENGTH can be set to a value lower than the width of the operation being carried out. The OpenGL specification allows for this (the source or destination lines will be overlapping). Previously, our implementation of Pixel Buffer Objects did not support this case and would throw an error.
  • Fixed a rare deadlock condition when running applications that use OpenGL in multiple threads on a Quadro GPU.

New in Nvidia Linux Display Driver 32-bit 346.59 (Apr 7, 2015)

  • Added support for the following GPUs:

  • GeForce GTX 950M
  • GeForce GTX 960M
  • GeForce GTX TITAN X
  • Fixed a bug that caused corruption when switching display modes in some applications that use transform feedback.
  • Fixed a bug that caused texture corruption on framebuffer depth attachments cleared using glClearTexImage().
  • Fixed a bug that artificially limited the maximum pixel clock on displays in some SLI Mosaic configurations.
  • Fixed a kernel memory leak that occurred when looping hardware-accelerated video decoding with VDPAU on Maxell-based GPUs.

  • Added support for the following GPUs:
  • Quadro K620M
  • Quadro K2200M
  • GeForce GTX 965M
  • Fixed a bug that could cause rendering corruption in GLX clients using PBOs and/or VBOs when using GLX indirect rendering.
  • Fixed a bug that caused Xinerama layouts which included X screens with 'Option "UseDisplayDevice" "none"' to be represented incorrectly in the nvidia-settings control panel.
  • Fixed a bug that could cause glXSwapBuffer() to block for longer than necessary in multi-threaded GLX applications using the GLX_NV_delay_before_swap extension.
  • Fixed a bug that caused OpenGL applications using the NV_path_rendering extension to crash after a modeswitch event.
  • Fixed a bug that caused DisplayPort audio to stop working after monitors are hotplugged.

New in Nvidia Linux Display Driver 32-bit 346.35 (Jan 18, 2015)

  • Added support for the following GPUs:
  • GeForce 800A
  • GeForce 800M
  • GeForce GTX 970M
  • GeForce GTX 980M
  • Added support for X.Org xserver ABI 19 (xorg-server 1.17).
  • Improved compatibility with recent Linux kernels.
  • Fixed a bug that prevented internal 4K panels on some laptops from being driven at a sufficient bandwidth to support their native resolutions.
  • Fixed a regression that prevented the NVIDIA kernel module from loading in some virtualized environments such as Amazon Web Services.
  • Fixed a regression that caused displays to be detected incorrectly on some notebook systems.
  • Fixed a bug that could cause X to freeze when using Base Mosaic.
  • Fixed a regression that prevented the NVIDIA X driver from recognizing Base Mosaic layouts generated by the nvidia-settings control panel.
  • Updated the NVIDIA X driver to reject frame packed interlaced HDMI 3D modes during mode validation. These modes were being validated by the driver, despite never having been supported.
  • Fixed a bug that prevented the console from being restored after forcefully terminating X, on some GPUs with multiple DisplayPort monitors attached. This bug also subsequently prevented X from being started following the failed console restoration.
  • Updated the version of libvdpau shipped with the driver to 0.9. This version honors the VDPAU_DRIVER_PATH environment variable and fixes a race condition if multiple threads call VdpDeviceCreateX11 simultaneously. See http://lists.freedesktop.org/archives/vdpau/2014-December/000274.html for more information.
  • Please note that users are encouraged to use their distribution's libvdpau packages rather than relying on the one shipped with the NVIDIA graphics driver.
  • Fixed a bug that caused the ACPI hotkey mask to be set incorrectly on some laptops even when the EnableACPIHotkeys option is disabled.
  • Disabled the EnableACPIHotkeys option by default. This option is now considered deprecated and will be removed in a future driver release. On modern Linux systems, display change hotkey events are delivered to the desktop environment as key press events, and the desktop environment handles the display change by issuing requests through the X Resize and Rotate extension (RandR).
  • Fixed a bug that caused the screen image to be shifted when screen transformations (such as rotations or reflections) were enabled on a G-SYNC display attached to a Kepler-based GPU.
  • Fixed a bug that caused a blank screen when setting a mode requiring YUV 4:2:0 compression. These modes are not currently supported.
  • Fixed a bug that caused an incorrect DisplayPort link configuration to be displayed after a hotplug or unplug.

  • EGL_EXT_device_base
  • EGL_EXT_platform_device
  • EGL_EXT_output_base
  • Added the ability to increase the operating voltage on certain GeForce GPUs in the GeForce GTX 400 series and later. Voltage adjustments are done at the user's own risk. See the documentation on the "CoolBits" X configuration option in the README for details.
  • Added support for NVENC on GeForce GPUs. For more details on the NVENC SDK, see: https://developer.nvidia.com/nvidia-video-codec-sdk.
  • Removed a sanity check in nvidia-installer that tested the availability of POSIX shared memory. The NVIDIA GPU driver has not required POSIX shared memory since release 270.xx.
  • Removed the NVIDIA Unified Memory kernel module, nvidia-uvm.ko, from the driver package on 32-bit architectures.
  • Added accelerated support for r8g8b8a8, r8g8b8x8, b8g8r8a8 and b8g8r8x8 RENDER formats.
  • Updated nvidia-settings to take advantage of GTK+ 3, when available. This is implemented by building the nvidia-settings user interface into separate shared libraries (libnvidia-gtk2.so, libnvidia-gtk3.so), and loading the correct one at run-time.
  • Added the nvidia-settings option --gtk-library to allow specifying the path of the directory containing the user interface library or the path and filename of the specific library to use.
  • Added support in nvidia-settings for a GTK+ 3 user interface on x86 and x86_64.
  • Added the nvidia-settings option --use-gtk2 to force the use of the GTK+ 2 UI library.
  • Updated nvidia-installer to install a file in the system's xorg.conf.d directory, when a sufficiently new X server is detected, to cause the X server to load the "nvidia" X driver automatically if it is started after the NVIDIA kernel module is loaded.
  • This feature is supported in X.Org xserver 1.16 and higher when running on Linux 3.9 or higher with CONFIG_DRM enabled.
  • Improved the performance of nvidia-installer by enabling the use of parallel make when building the NVIDIA kernel modules. The concurrency level can be set with the --concurrency-level option, and defaults to the number of detected CPUs.
  • Updated nvidia-installer to determine default installation locations for libraries based on the presence of known paths in the ldconfig(8) cache and the filesystem, rather than hardcoded distro-specific paths.
  • Fixed a GLSL compiler bug that would produce corruption when running games such as Far Cry 3 in Wine.
  • Fixed the EGL_KHR_stream_cross_process_fd extension.
  • Fixed rendering corruption that sometimes happened when calling DrawElementsInstancedBaseVertexBaseInstance(), DrawElementsInstancedBaseInstance(), or DrawArraysInstancedBaseInstance().
  • Dramatically improved OpenGL Framebuffer Object creation performance.
  • Removed the limit on the maximum number of OpenGL Framebuffer Objects.
  • Updated the NVIDIA OpenGL driver to prefer $XDG_CACHE_HOME over $HOME as the default location for storing the GL shader disk cache.

  • /usr/lib/nvidia/alternate-install-present
  • These files may be provided by NVIDIA driver installers other than the official .run package maintained by NVIDIA, to alert nvidia-installer to the presence or availability of an alternative installation method. See the nvidia-installer(1) manual page for more information.
  • Fixed an X driver bug where the RandR CRTC panning area and tracking area were not getting clamped to the current X screen size when the RandR CRTC transitioned from disabled to enabled.
  • Fixed an X driver bug where successful RandR X_RRSetScreenConfig requests would update the server's RandR 'lastSetTime' too far, potentially causing subsequent RandR requests to be unnecessarily
  • rejected.
  • Fixed an X driver bug that caused GPUs to become inaccessible via the NV-CONTROL X extension when no corresponding X screens could be initialized.
  • Generate a BadMatch error when applications attempt to create GLX pixmaps using glXCreatePixmap() or glXCreateGLXPixmapWithConfigSGIX() and the pixmap's depth doesn't match that of the specified GLXFBConfig.
  • Updated nvidia-settings to explicitly specify the direction of rotation for configuring per-display rotation configuration.
  • Honor a GPU UUID as the GPU qualifier for X configuration options that allow GPU qualifiers (e.g. "MetaModes").
  • Report GPU UUIDs in the X log when verbose logging is enabled in the X server.
  • Enabled conformant glBlitFrameBuffer() scissor test behavior by default. A driver-provided application profile enables the previous non-conformant behavior for applications that load libcogl, to work around a bug in older versions of libcogl.
  • Application profiles can be added to enable the non-conformant behavior
  • for other applications that depend upon it. See the "Known Issues"
  • section of the README for more details.
  • Fixed a bug that caused applications using CUDA-GL interop to crash when run on X servers with Xinerama enabled.

  • Fixed a bug which could cause a blank screen when changing house sync settings on Quadro Kepler GPUs with Quadro Sync boards.
  • Fixed a bug that prevented nested loops with identical loop conditions in GLSL shaders from terminating correctly. This could cause hangs in applications such as Exa PowerVIZ.
  • Fixed a bug that resulted in corrupt texels when a previously empty texture image was specified with glXBindTexImageEXT. In GNOME 3, this caused gnome-screenshot to produce garbled window screenshots.
  • Fixed a bug that caused the X server to crash when querying the current mode of disabled displays.

New in Nvidia Linux Display Driver 32-bit 331.20 (Nov 9, 2013)

  • Added support for NVIDIA OpenGL-based Framebuffer Capture (NvFBCOpenGL). This library provides a high performance, low latency interface to capture and optionally encode the composited framebuffer of an X screen. NvFBC and NvIFR are private APIs that are only available to approved partners for use in remote graphics scenarios. Please contact NVIDIA at [email protected] for more information.
  • Fixed a bug that prevented configuration files containing application profiles from being loaded when directories were present in the application profile configuration search path.

  • For example, `nvidia-settings --query=[fan:0]/GPUCurrentFanSpeedRPM`.
  • Fixed a regression that caused GPUs that do not support graphics to not appear in nvidia-settings.
  • Fixed a bug that caused DisplayPort 1.2 multi-stream devices to stop working if they were unplugged and plugged back in while they were active in the current MetaMode.
  • Added support for multiple NVIDIA kernel modules. This feature allows users to assign different GPUs in the system to different NVIDIA kernel modules, potentially reducing the software overhead of coordinating access to multiple GPUs.
  • Added support for the EGL API on 32-bit platforms. Currently, the supported client APIs are OpenGL ES 1.1, 2.0 and 3.0, and the only supported window system backend is X11.
  • Add a new option, AllowEmptyInitialConfiguration, which allows the X server to start even if no connected display devices are detected at startup. This option can be enabled by running "sudo nvidia-xconfig --allow-empty-initial-configuration"
  • This option is useful in RandR 1.4 display offload configurations where no display devices are connected to the NVIDIA GPU when the X server is started, but might be connected later.
  • Updated nvidia-installer to provide a scrollable text area for displaying messages from the /usr/lib/nvidia/alternate-install-present and /usr/lib/nvidia/alternate-install-available distro hook files. This allows for longer messages to be provided in these files.
  • Updated nvidia-installer to avoid recursing into the per-kernel "build" and "source" directories when searching for conflicting kernel modules in /lib/modules.
  • Added a system memory cache to improve the performance of certain X rendering operations that use software rendering fallbacks. The X configuration option "SoftwareRenderCacheSize" may be used to configure the size of the cache.
  • Removed the "DynamicTwinView" X configuration option: dynamic reconfiguration of displays is always possible, and can no longer be disabled.
  • Fixed a bug that caused nvidia-settings to display incorrect information in its display configuration page when all displays on an X screen were turned off.
  • Updated nvidia-installer to only install the libraries libvdpau and libvdpau_trace if an existing installation of libvdpau is not detected on the system. This behavior can be overridden with the --install-vdpau-wrapper and --no-install-vdpau-wrapper options.
  • Future NVIDIA Linux installer packages will no longer include copies of libvdpau or libvdpau_trace: VDPAU users are recommended to install these libraries via other means, e.g. from packages provided by their distributors, or by building them from the sources available at: http://people.freedesktop.org/~aplattner/vdpau/

  • Fixed a bug that caused DisplayPort monitors connected to Quadro FX 3800, 4800, or 5800 to remain off after DPMS.
  • Added the NVIDIA OpenGL-based Inband Frame Readback (NvIFROpenGL) library to the Linux driver package. This library provides a high performance, low latency interface to capture and optionally encode an individual OpenGL framebuffer. NvIFROpenGL captures pixels rendered by OpenGL only and is ideally suited to application capture and remoting.
  • Fixed a bug that caused applications using CUDA-GL interop to crash when run on X servers with Xinerama enabled.
  • Fixed a bug that could prevent some double-bit ECC errors from being properly reported.
  • Fixed a bug which could cause a blank screen when changing house sync settings on Quadro Kepler GPUs with Quadro Sync boards.
  • Fixed a bug that prevented nested loops with identical loop conditions in GLSL shaders from terminating correctly. This could cause hangs in applications such as Exa PowerVIZ.
  • Fixed a bug that resulted in corrupt texels when a previously empty texture image was specified with glXBindTexImageEXT. In GNOME 3, this caused gnome-screenshot to produce garbled window screenshots.
  • Fixed a bug that caused the X server to crash when querying the current mode of disabled displays.

  • Fixed a bug that caused corrupted window content in some cases when moving GLX windows with antialiasing enabled.
  • Fixed a bug that caused DisplayPort devices that failed link training to be reported as connected rather than disconnected.
  • Fixed a regression that could cause a DisplayPort device that was connected to one connector to turn off when a DisplayPort device on a different connector was connected or disconnected.
  • On Kepler-based GPUs, improved the appearance of the tearing that occurs when using RandR 1.4's Source Output capability.While tearing is still expected, the tears should now appear as horizontal lines rather than more noticeable checkerboard or triangular shapes.
  • Added a "Prefer Consistent Performance" PowerMizer Mode to the nvidia-settings control panel, available on Quadro boards that support this feature.

New in Nvidia Linux Display Driver 32-bit 319.23 (May 23, 2013)

  • Added support for the following GPUs:
  • GeForce GTX 780

  • Added support in VDPAU for 4k resolution MPEG-1/2 and H.264 video decoding, up to 4032x4048 for MPEG-1/2 and 4032x4080 for H.264, and up to 65536 macroblocks for both.

New in Nvidia Linux Display Driver 32-bit 319.17 (May 2, 2013)

  • Added support for the following GPU:
  • GeForce GTX 650 Ti BOOST
  • GeForce GT 720M
  • GeForce GT 735M
  • GeForce GT 740M
  • GeForce GT 745M
  • GeForce GT 750M
  • Fixed a regression that caused multiple BUG messages to be printed in the kernel log on SMP systems.
  • Fixed a bug that could cause the X server to crash when repeatedly enabling and disabling displays.
  • Updated nvidia-settings to preserve the relative positioning of displays when changing from a layout where multiple displays are on the same X screen to one where the same displays span multiple X screens.
  • Fixed nvidia-settings to dlopen(3) "libvdpau.so.1", rather than "libvdpau.so".
  • Added nvidia-persistenced, a daemon utility, to the driver package. nvidia-persistenced can be installed to run on system startup or manually run to allow the NVIDIA kernel module to keep persistent driver state allocated when no other user-space NVIDIA driver components are running.This can improve startup time for other user-space NVIDIA driver components.
  • Fixed CVE-2013-0131: NVIDIA UNIX GPU Driver ARGB Cursor Buffer Overflow in "NoScanout" Mode. This buffer overflow, which occurred when an X client installed a large ARGB cursor on an X server running in NoScanout mode, could cause a denial of service (e.g., an X server segmentation fault), or could be exploited to achieve arbitrary code execution.
  • For more details, see: http://nvidia.custhelp.com/app/answers/detail/a_id/3290
  • Added initial support for restoration of efifb consoles on UEFI systems where the primary display is driven over VGA or TMDS (e.g. DVI, HDMI, or LVDS).
  • Added support for the xorg.conf Monitor section options "Ignore", "Enable", "Primary", and "Rotate".For example, to rotate a monitor identified by a specific EDID hash, one could add the following to /etc/X11/xorg.conf or a file in /etc/X11/xorg.conf.d:
  • Section "Monitor"
  • Identifier "DPY-EDID-ee6cecc0-fa46-0c33-94e0-274313f9e7eb"
  • Option "Rotate" "left"
  • EndSection
  • See the README and the xorg.conf(5) man page for more information.

  • Added support for RandR 1.3 panning.
  • Improved performance when the Accel option is disabled.
  • Added initial support for RandR 1.4 Provider objects with the Source Output capability, which can be used to render the desktop on an NVIDIA GPU and display it on an output connected to a provider with the Sink Output capability, such as an Intel integrated graphics device or a DisplayLink USB-to-VGA adapter.See the README for details.
  • Added nvidia-modprobe, a setuid root utility, to the driver package. nvidia-modprobe can be used by user-space NVIDIA driver components to make sure the NVIDIA kernel module is loaded and that the NVIDIA character device files are present.When possible, it is recommended to use Linux distribution native mechanisms for managing kernel module loading and device file creation. This utility is provided as a fallback to work out-of-the-box in a distribution-independent way.
  • Updated the nvidia-settings command line interface to accept display device names, as well as optional target qualifiers, e.g.
  • nvidia-settings -q [DVI-I-0]/RefreshRate
  • nvidia-settings -q [GPU-1.DVI_I-1]/RefreshRate
  • Updated the nvidia-settings command line interface to no longer assume the "X screen 0" target, when no target is specified in query and assign operations.Instead, all valid targets of the attribute are processed.
  • Fixed a memory leak that occurred when destroying a GLX window but not its associated X window.
  • Fixed a bug that could cause nvidia-installer to fail to delete directories created as part of a previous installation.
  • Updated nvidia-installer to report failures to remove installed files or restore backed up files with a single warning message, instead of a separate message for each individual failure.
  • Improved the performance of modesets in cases where the mode timings remained the same, but other parameters of the mode configuration, such as the ViewPort or panning domain, changed.
  • Fixed an issue with RENDER convolution filters.The driver will no longer normalize filter kernels before accelerating them.
  • Improved debuggability of the NVIDIA OpenGL libraries by including proper stack unwinding information on all supported architectures.
  • Updated the dkms.conf file and the makefile for the NVIDIA Linux kernel module to allow DKMS installations on systems with separate source and output directories.
  • Fixed a bug that caused RENDER Pictures to be sampled incorrectly when using nearest filtering in some cases.
  • Added support for the RandR "Border" and "BorderDimensions" Output properties, which can be used to configure the ViewPortOut of an RandR output.This is functionally equivalent to the "ViewPortOut" MetaMode token.
  • Fixed a bug where RRGetCrtcInfo could report incorrect size information when an RandR output has a custom ViewPortIn.
  • Further improve performance of some versions of HyperMesh with Quadro GPUs.
  • Added a VDPAU page to the nvidia-settings control panel, to display information about the decoding capabilities of VDPAU-capable GPUs.
  • Added support for dynamic mode management through RandR, e.g. via the --newmode, --rmmode, and --delmode options in xrandr(1).
  • Increased the number of pages that are shareable across multiple processes in the x86 build of libnvidia-glcore.so, by reducing its R_386_PC32 relocation count.
  • Fixed a bug that caused XVideo applications to receive BadAlloc errors after VT switches and mode switches that occurred while a composite manager was running.
  • Removed the X driver's support for "CursorShadow".
  • Updated nvidia-installer to attempt unprelinking files whose checksums do not match the checksums recorded at installation time.
  • Switched .run package compression from gzip to xz.This provides a higher level of compression.

New in Nvidia Linux Display Driver 32-bit 310.44 (Apr 2, 2013)

  • Fixed CVE-2013-0131: NVIDIA UNIX GPU Driver ARGB Cursor Buffer Overflow in "NoScanout" Mode. This buffer overflow, which occurred when an X client installed a large ARGB cursor on an X server running in NoScanout mode, could cause a denial of service (e.g., an X server segmentation fault), or could be exploited to achieve arbitrary code execution.

  • Fixed a bug that sometimes prevented rotation controls in the nvidia-settings control panel from working after changing resolutions.
  • Fixed a bug that could cause applications using GL_NV_vdpau_interop to crash during modeswitches.
  • Fixed a regression that could cause OpenGL applications to crash while compiling shaders.
  • Added a kernel module parameter, "NVreg_EnablePCIeGen3", which can be used to enable PCIe gen 3 when possible. Note that on many systems where the NVIDIA driver does not allow PCIe gen 3 by default, stability problems can be expected when this option is enabled: users should do so at their own risk.
  • Fixed a VDPAU bug that could cause the X server to hang when decoding some corrupted video streams.
  • Renamed VGX products to GRID products in the "Supported NVIDIA GPU Products" list.
  • Added support for X.org xserver ABI 14 (xorg-server 1.14).
  • Fixed a bug in nvidia-settings that could cause the wrong resolution to be set in basic mode for setups based on one display per X screen.
  • Fixed libnvidia-encode.so library dependency by linking it with libnvcuvid.so.1 instead of libnvcuvid.so while creating it.
  • Improved performance of OpenGL framebuffer object binds with Xinerama enabled by 2000-3000% when the application's windows do not span screen boundaries.

  • Fixed a hang when using OpenGL programs with some SLI Mosaic configurations on pre-Fermi GPUs.
  • Added sections to the "Supported NVIDIA GPU Products" list for NVS, Tesla, and VGX products.

New in Nvidia Linux Display Driver 32-bit 304.60 (Oct 19, 2012)

  • Fixed a bug that caused the X server to crash if a display was put into DPMS off mode and subsequently reenabled while screen transformations are in use.
  • Fixed a bug that caused the X Resize and Rotate extension to be enabled when Xinerama is enabled. These two X extensions are incompatible and having them both enabled can confuse window managers such as KDE's kwin. RandR is now correctly disabled when Xinerama is enabled.
  • Fixed a bug causing OpenGL stereo applications to not work properly when using passive stereo modes 5 through 9 on Quadro Fermi and newer GPUs.
  • Updated nvidia-settings to report Dedicated GPU Memory (i.e., the memory dedicated exclusively to the GPU) and Total GPU Memory (i.e., Dedicated GPU Memory plus any TurboCache(TM)-accessible system memory) separately on the GPU information page.
  • Added reporting of the current utilization of Dedicated GPU Memory to the GPU information page of nvidia-settings.
  • Added support for the "Backlight" RandR output property for configuring the brightness of some notebook internal panels.

  • Fixed a bug that caused VDPAU to hang when expanding the YouTube Flash Player.
  • Fixed a bug that caused gnome-settings-daemon to revert display configuration changes made by nvidia-settings.
  • Updated nvidia-settings to use RandR per-CRTC gamma control, when available. When controlling an X server with support for RandR 1.2, nvidia-settings will display the color correction widget as a tab within each display device page, instead of a per-X screen color correction page.
  • Fixed a bug that prevented the display palette from being updated immediately after an application called XStoreColors.
  • Added the ability to select and move X screens in the "X Server Display Configuration" page of nvidia-settings via Ctrl-(Left)Click + Drag.

New in Nvidia Linux Display Driver 32-bit 304.37 (Aug 14, 2012)

  • Added support for the following GPUs:

  • Quadro K2000M
  • Tesla K10
  • Removed the ability to enable SLI on GPUs with ECC enabled.
  • Fixed several bugs that prevented some RandR transform geometries from being applied.
  • Fixed a bug that caused frequent hangs or crashes on some systems.
  • Fixed a bug that would cause corruption and performance issues in certain OpenGL applications such as Amnesia: The Dark Descent on GeForce 6 and 7 GPUs.
  • Fixed a bug that caused applications that use DirectColor visuals, such as Enemy Territory: Quake Wars and Braid, to appear in shades of blue instead of the correct colors.
  • Modified handling of RRSetScreenSize requests to ignore requests that do not actually resize the screen.This reduces screen flicker in certain cases when using GNOME.
  • Added a new option, "--disable-nouveau" to nvidia-installer. This option changes the action that is chosen by default when Nouveauis detected by nvidia-installer. If the "--disable-nouveau" optionis set, then the default will be to attempt to disable Nouveau when it is detected; otherwise, no attempt will be made unless requested.
  • Added support for xserver ABI 13 (xorg-server 1.13).
  • Added support for RandR per-CRTC gamma manipulation through the RandR 1.2 RRGetCrtcGammaSize, RRGetCrtcGamma, and RRSetCrtcGamma requests.
  • Fixed a bug that caused RRSetOutputPrimary requests to incorrectly generate BadValue errors when setting the primary output to None.This caused gnome-settings-daemon to crash after changing the screen configuration in response to a display hotplug or the display change hot-key being pressed.
  • Fixed a problem where RENDER Glyphs operations would exhibit severe performance issues in certain cases, such as when used with gradients by Cairo and Chromium.
  • Fixed a bug that caused X to hang when resuming certain DisplayPort display devices (such as Apple brand mini-DisplayPort to dual-link DVI adapters) from power-saving mode.
  • Fixed a bug that caused an X screen to be extended to Quadro SDI Output devices by default. An X screen will still use an SDI Output device if it is the only display device available. To use a SDI Output device on an X screen with other display devices available, include the SDI Output device with either the "UseDisplayDevice" or "MetaMode" X configuration options.
  • Updated X11 modeline validation such that modes not defined in a display device's EDID are discarded if the EDID 1.3 "GTF Supported" flag is unset or if the EDID 1.4 "Continuous Frequency" flag is unset. The new "AllowNonEdidModes" token for the ModeValidationX configuration option can be used to disable this new check.
  • Fixed a bug, introduced in the 295.xx release series, with EDID detection on some laptop internal panels. This bug caused the laptop internal panel to show six small copies of the desktop.
  • Added support for FXAA, Fast Approximate Anti-Aliasing. Using regular anti-aliasing modes or Unified Back Buffers with FXAA is not currently supported.
  • Enhanced the functionality of the IncludeImplicitMetaModes X configuration option: Implicit MetaModes will be added for the primary display device, even if multiple display devices are in use when X is initialized.
  • Implicit MetaModes will be added for common resolutions, even
  • if there isn't a mode with that resolution in the mode pool of
  • the display device.
  • Extended the syntax of the IncludeImplicitMetaModes X
  • configuration option, e.g., to control which display device is
  • used for creation of implicit MetaModes.
  • See the description of the IncludeImplicitMetaModes X configuration
  • option in the README for details.
  • Modified the handling of the RandR 1.0/1.1 requests RRGetScreenInfo and RRSetScreenConfig (e.g., `xrandr -q --q1` and `xrandr --size ...` and `xrandr --orientation ...`) such that they operate on MetaModes. This was the behavior in NVIDIA X driver versions 295.xx and earlier, but 302.xx releases altered the handling of these RandR 1.0/1.1 requests to operate on a single RandR output's modes.
  • With the above changes to IncludeImplicitMetaModes and RandR 1.0/1.1 handling, fullscreen applications (e.g., SDL-based applications, Wine), should have more resolutions available to them, and should interact better with multiple monitor configurations.
  • Fixed a bug that could cause G8x, G9x, and GT2xx GPUs to display a black screen or corruption after waking up from suspend.
  • Fixed several bugs that could cause some OpenGL programs to hang when calling fork(3).
  • Fixed an nvidia-settings bug that caused the results of ProbeDisplays queries made with the --display-device-string option to be formatted incorrectly.
  • Improved the responsiveness of updates to the nvidia-settings control panel when displays are hotplugged.
  • Fixed a bug that caused display corruption when setting some transforms, especially when panning a transformed display.
  • Fixed a bug that caused extra RandR events to be generated the first time a display is hotplugged.
  • Fixed a bug that caused X11 modelines with '@' in their names to be rejected.
  • Added support for DisplayPort 1.2 branch devices, which allow multiple displays to be connected to a single DisplayPort connector on a graphics board.
  • Fixed a bug that caused most OpenGL texture uploads to be slow when the context was bound rendering to an RGB overlay drawable.
  • Fixed a bug that caused audio over HDMI to not work after restarting the X server on some MCP7x (IGP) GPUs.
  • Updated the X configuration option "UseDisplayDevice" to honor the value "none" on any GPU.
  • Added support for DKMS in nvidia-installer. Installing the kernel module through DKMS allows the module to be rebuilt automatically when changing to a different Linux kernel. See the README and the nvidia-installer help text for the "--dkms" option.
  • Added RandR output properties _ConnectorLocation, ConnectorNumber, ConnectorType, EDID, _GUID, and SignalFormat. See the README for details on these properties.
  • Extended support for Base Mosaic to all G80+ SLI configurations with up to three displays.
  • Fixed a bug that caused some monitors to fail to wake from DPMS suspend mode when multiple DisplayPort monitors were attached to one GPU.
  • Removed controls for XVideo attributes from the "X Server XVideo Settings" page of the nvidia-settings control panel. XVideo attributes can be configured in XVideo player applications, or through utilities such as xvattr.
  • Fixed a bug that caused all ports on an XVideo adaptor to share color correction settings.
  • Removed support for the following X configuration options:
  • SecondMonitorHorizSync
  • SecondMonitorVertRefresh
  • Similar control is available through the NVIDIA HorizSync and
  • VertRefresh X configuration options. Please see the NVIDIA driver
  • README for details.
  • Fixed a bug that prevented NVIDIA 3D Vision Pro from working properly when switching between X servers on different VTs.
  • Added support for desktop panning when rotation, reflection, or transformation is applied to a display device (either through RandR or through the MetaMode syntax); panning would previously be ignored in that case.
  • Implemented hotfix for a privilege escalation vulnerability reported on August 1, 2012. For more details, see:
  • http://nvidia.custhelp.com/app/answers/detail/a_id/3140

New in Nvidia Linux Display Driver 32-bit 302.17 (Jun 16, 2012)

  • Made nvidiaXineramaInfoOrder consistent with the RRSetOutputPrimary and RRGetOutputPrimary RandR requests: changes to either nvidiaXineramaInfoOrder or RandR OutputPrimary will be reflected in the other.
  • Fixed an interaction problem between RandR 1.2, ConstrainCursor, and panning that prevented panning from working properly.
  • Fixed a bug that caused RandR RRNotify_CrtcChange events to not be generated when switching between MetaModes with the same total size but different layout of display devices. This bug caused some window managers to not update their layouts in response to switching same-sized MetaModes.
  • Added support for desktop panning when rotation, reflection, or transformation is applied to a display device (either through RandR or through the MetaMode syntax); panning would previously be ignored in that case.
  • Added an "EDID" property to RandR 1.2 outputs. This property contains the binary contents of the connected monitor's extended display identification data, which allows applications such as the GNOME display properties dialog to query information about it.
  • Fixed a bug that caused audio over HDMI to not work on some GPUs after querying the RandR configuration (e.g., `xrandr -q`).
  • Added the "nvidiaXineramaInfo" X configuration option to report the layout of multiple display devices within an X screen. This is enabled by default. When disabled on X servers with RandR 1.2 support, the NVIDIA X driver will report one screen-sized region. When disabled on X servers without RandR 1.2 support, no Xinerama information will be reported. For backwards compatibility, the "NoTwinViewXineramaInfo" option disables nvidiaXineramaInfo.
  • Added the "nvidiaXineramaInfoOrder" X configuration option as a replacement for "TwinViewXineramaInfoOrder". For backwards compatibility, "TwinViewXineramaInfoOrder" is kept as a synonym for "nvidiaXineramaInfoOrder".
  • Added the "nvidiaXineramaInfoOverride" X configuration option as a replacement for "TwinViewXineramaInfoOverride". For backwards compatibility, "TwinViewXineramaInfoOverride" is kept as a synonym for "nvidiaXineramaInfoOverride".
  • Fixed a bug that prevented the use of some SLI Mosaic topologies.
  • Added the "MetaModeOrientation" X configuration option as a replacement for "TwinViewOrientation". "TwinViewOrientation" is kept as a synonym for "MetaModeOrientation", for backwards compatibility.
  • Added support for calculating the physical size and DPI of each RandR 1.2 Output using the EDID Detailed Timing Description.
  • Fixed a bug that prevented a workaround for the invalid EDID in certain AUO laptop flat panels from being applied, leading to an 800x600 desktop repeated several times across the screen.
  • Fixed a bug that caused the link configuration of DisplayPort devices to be reported incorrectly in nvidia-settings.
  • Fixed a bug that caused OpenGL programs to leak file descriptors when calling exec() on themselves.
  • Fixed rendering corruption at the start of new X server generation.
  • Added X driver support for RandR 1.2 and RandR 1.3. See "Support for the X Resize and Rotate Extension" in the README for details.
  • Extended the MetaMode X configuration option syntax with the following new attributes:
  • "Rotation" : specifies the display device's rotation
  • "Reflection" : specifies the display device's reflection
  • "Transform" : specifies a 3x3 transformation matrix to be
  • applied to the display device
  • "ViewPortOut" : specifies the region of the mode in which to
  • display pixels
  • "ViewPortIn" : specifies the size of the region in the X screen
  • to display in the ViewPortOut
  • For example, "DFP-0: nvidia-auto-select { Rotation=left }".
  • See "Configuring Multiple Display Devices on One X Screen" in the
  • README for details.
  • Removed the "TwinView" X configuration option; the functionality it provided is now enabled by default.
  • Previously, the NVIDIA X driver only enabled one display device for an X screen unless "TwinView" was enabled. Now, the NVIDIA X driver enables, by default, as many display devices as the GPU supports driving simultaneously. To limit how many display devices are driven by an X screen, use the "UseDisplayDevice" X configuration option.
  • Added a "CurrentMetaMode" attribute to the nvidia-settings command line, to query and set the current MetaMode.
  • As an example, these two commands are equivalent:
  • xrandr --output DVI-I-2 --mode 1280x1024 --pos 0x0 --output DVI-I-3 --mode 1920x1200 --pos 1280x0
  • nvidia-settings --assign CurrentMetaMode= "DVI-I-2: 1280x1024 +0+0, DVI-I-3: 1920x1200 +1280+0"
  • Removed overscan compensation configurability from NV-CONTROL and nvidia-settings. This can be configured, with finer granularity, through the ViewPortIn and ViewPortOut MetaMode attributes.See "Configuring Multiple Display Devices on One X Screen" in the README for details.
  • Altered mode validation such that for digital display devices the X driver only allows, by default, modes which are reported in the EDID. Previously, the NVIDIA X driver allowed other modes, but implicitly scaled those other modes to one of the EDID modes.
  • Now, only the modes in the EDID are validated and the X driver does not do any implicit scaling. Any desired scaling can be configured explicitly through the new "ViewPortIn" and "ViewPortOut" MetaMode attributes. See "Configuring Multiple Display Devices on One X Screen" in the README for details.
  • Removed Flat Panel Scaling configurability in nvidia-settings. Any desired scaling can be configured through the new "ViewPortIn" and "ViewPortOut" MetaMode attributes.
  • Hotplug events (specifically, the RRNotify_OutputChange RandR event) are now generated when display devices are connected and disconnected from the GPU. Many desktop environments automatically
  • resize the X desktop in response to these events.
  • Added display device name aliases, such that X configuration options that use display device names can refer to a display device by one of several names, including the RandR Output name for the display device. The X log reports the list of aliases for each display device.
  • Updated EDID parsing to include more complete support for EDID 1.4 and more recent versions of CEA-861.
  • Removed the "Rotate" X configuration option. This was used to statically rotate the X screen. Its functionality is replaced by the "Rotation" MetaMode attribute and RandR 1.2 rotation support. See the README for details.
  • Removed the "RandRRotation" X configuration option. This enabled configurability of X screen rotation via RandR 1.1. Its functionality is replaced by the "Rotation" MetaMode attribute and RandR 1.2 rotation support. See the README for details.
  • Removed support for the following NV-CONTROL attributes:
  • NV_CTRL_GPU_SCALING
  • NV_CTRL_GPU_SCALING_DEFAULT_TARGET
  • NV_CTRL_GPU_SCALING_DEFAULT_METHOD
  • NV_CTRL_DFP_SCALING_ACTIVE
  • NV_CTRL_GPU_SCALING_ACTIVE
  • NV_CTRL_FRONTEND_RESOLUTION
  • NV_CTRL_BACKEND_RESOLUTION
  • NV_CTRL_OVERSCAN_COMPENSATION
  • NV_CTRL_FLATPANEL_BEST_FIT_RESOLUTION
  • Improved rendering performance for RENDER bitmap text.
  • Enabled the OpenGL "Sync to VBlank" option by default.
  • Added a new option, --restore-original-backup, to nvidia-xconfig. nvidia-xconfig creates a backup of the original X configuration file when modifying an X configuration file that does not appear
  • to have been previously modified by nvidia-xconfig. This option restores a backup of the original X configuration file, if such a backup is found.
  • Expose the following additional FSAA modes via NV-CONTROL, nvidia-settings, and through X visuals and GLXFBConfigs:
  • 16X multisample FSAA on all GeForce GPUs
  • Coverage sample FSAA on G80 and above GeForce GPUs
  • 32X multisample FSAA on G80 and above Quadro GPUs
  • 64X multisample FSAA on Fermi and above Quadro GPUs
  • Enabled conformant texture clamping by default in OpenGL.
  • Removed support for the GVO Clone mode NV-CONTROL attributes:
  • NV_CTRL_GVO_DISPLAY_X_SCREEN
  • NV_CTRL_GVO_X_SCREEN_PAN_X
  • NV_CTRL_GVO_X_SCREEN_PAN_Y
  • Added a new, higher resolution icon for nvidia-settings.
  • Updated the NVIDIA X driver's handling of X configuration options that affect an entire GPU, not just a particular X screen running on a GPU (e.g., "NoPowerConnectorCheck"): for such X configuration options, the X driver will now honor the option on any of the X screens configured on the GPU. Prior to this change, the NVIDIA X driver only honored such options on the first X screen configured on a GPU.
  • Added a checkbox to nvidia-settings to control the texture clamping attribute. When the box is checked, OpenGL textures are clamped according to the OpenGL specification. When it is unchecked, GL_CLAMP is remapped to GL_CLAMP_TO_EDGE for borderless 2D textures.
  • Removed the "Display" and "X Screen" tabs from the "X Server Display Configuration Page" of nvidia-settings, and added a new "Selection" dropdown menu for selecting X screens or display devices. This makes it easier to select X screens/Displays that are hidden.

  • Fixed a bug that could result in line flickering in full-scene anti-aliasing contexts.
  • Fixed a bug that caused the physical dimensions of rotated monitors to be reported incorrectly.
  • Add support for the pre-VBO DrawArrays command in the server-side GLX driver module. The NVIDIA client-side GLX implementation never sends this command, but the server needs to support it for compatibility with other GLX client implementations.
  • Fixed a regression that caused blank/white windows when exhausting video memory on GeForce 6 and 7 series GPUs while using composited desktops.
  • Fixed a bug that would cause applications which export custom allocation functions to our driver (such as Adobe Flash in Firefox or Chrome) to crash.
  • Fixed a bug that prevented the driver from loading on some systems with integrated graphics.
  • Fixed issues in VDPAU that prevented allocating and displaying extremely large VdpOutputSurfaces.
  • Added support for limiting heap allocations in the OpenGL driver through the use of the __GL_HEAP_ALLOC_LIMIT environment variable. See the README for further details.
  • Added an "Accel" option to the X driver to allow disabling its use of the graphics processing hardware. This is useful when other components, such as CUDA, require exclusive use of the GPU's processing cores.
  • Modified how the OpenGL driver allocates executable memory so it may continue to function properly if /tmp is mounted noexec. As some fallback allocation methods may be prohibited under SELinux policy, the driver now supports detection of this policy as well as manual override of this detection via the __GL_SELINUX_BOOLEANS environment variable.
  • Fixed a bug that caused various GLSL built-in uniforms to not be updated properly when calling glPopAttrib.
  • Improved performance by caching compiled OpenGL shaders to disk. Added a "GLShaderDiskCache" option to the X driver to enable/disable this feature.

  • Fixed a corner-case in which the OpenGL driver could leak resources in applications utilizing fork().
  • Addressed a Linux kernel interface compatibility problem that could lead to ioremap() errors and, potentially, functional and/or stability problems.
  • Fixed a bug that caused SLI initialization to fail on some Intel based systems.
  • Fixed a bug that caused SLI initialization to fail when using recent Linux kernels, such as 2.6.38.

New in Nvidia Linux Display Driver 32-bit 270.41.06 (Apr 21, 2011)

  • NVS 4200M
  • Quadro 1000M
  • Quadro 2000M
  • Quadro 2000 D
  • Quadro 400
  • Added support for xserver ABI 10 (xorg-server 1.10).
  • Added NV-CONTROL event notification for NV_CTRL_FRAMELOCK_SYNC_READY status changes.
  • Added a new X configuration option "Interactive", which defaults to enabled, but can be disabled to allow long-running GPU compute programs to run concurrently with X.
  • Fixed a bug in the VDPAU presentation queue that could cause VDPAU "display preemption" when rendering to tiny or zero-sized windows or pixmaps.
  • Fixed a bug in VDPAU which prevented use of the overlay presentation
  • Fixed a bug in VDPAU that prevented the overlay from ever being used if a presentation queue was created while the target window was redirected using the Composite extension when the presentation queue was created.
  • Reorganized the NVIDIA driver's /proc file system layout to better reflect current needs: /proc/driver/nvidia/cards/0..N has been moved to /proc/driver/nvidia/gpus/0..N/information
  • Added new shared library: libnvidia-ml.so.
  • NVML provides programmatic access to static information and monitoring
  • data for NVIDIA GPUs, as well as limited managment capabilities. It is
  • intended for use with Tesla compute products.
  • See web-based documentation and associated nvml.h header for more info.
  • Added a new X configuration option "3DVisionDisplayType" to specify the display type when NVIDIA 3D Vision is enabled with a non 3D Vision ready display.
  • Fixed several bugs relating to hardware-accelerated gradients, which were causing visual corruption in some of the default Ubuntu GNOME themes.
  • Added unofficial GLX protocol support (i.e., for GLX indirect rendering) for the following OpenGL extensions:
  • GL_ARB_shader_subroutine

  • GL_NV_half_float
  • GL_NV_occlusion_query
  • GL_EXT_blend_equation_separate
  • GL_EXT_depth_bounds_test
  • Modified colormap updates to no longer be synchronized to vblank. This allows applications to send XStoreColor and XStoreColors requests faster than the screen's refresh rate.
  • This behavior can be controlled by a new NV-CONTROL attribute, NV_CONTROL_SYNC_LUT_UPDATES. By default, LUT updates are not synchronized. This may cause flickering in some applications that use the colormap to perform animation, such as xpilot running on a depth 8 X screen. If you experience flickering, try running nvidia-settings -a [gpu:0]/SynchronousPaletteUpdates=1

New in Nvidia Linux Display Driver 32-bit 260.19.44 (Mar 9, 2011)

  • Removed the requirement that in active stereo, all monitors must use identical modetimings.
  • Enhanced VDPAU to better report certain kinds of initialization error.
  • Fixed a regression that caused Xv to return BadAlloc errors on AGP systems when using the AGP GART driver contained in the NVIDIA driver.This fixes the problem reported in nvnews.net thread 151199.

New in Nvidia Linux Display Driver 32-bit 256.35 (Jun 24, 2010)

  • Fixed a regression in 256.29 where Performance Level clock frequencies were reported incorrectly in nvidia-settings.
  • Fixed a 3D Vision Stereo bug that caused the stereo glasses to not toggle when the flat panel was not running at its native mode timings.
  • Fixed a bug that caused nvidia-settings to crash when rendering its thermal gauge widget if the range of valid values for the thermal sensor was empty.
  • Fixed a bug which prevented use of high performance PowerMizer levels on systems with certain ACPI configurations.
  • Fixed a bug that caused non-primary Fermi GPUs to fail to initialize framebuffer memory. This caused a variety of symptoms, up to and including system hangs.
  • Added unofficial GLX protocol support (i.e., for GLX indirect rendering) for the following OpenGL extensions:
  • GL_ARB_blend_func_extended
  • GL_ARB_draw_buffers_blend
  • GL_ARB_sample_shading
  • GL_ARB_timer_query
  • GL_EXT_draw_buffers2
  • GL_EXT_separate_shader_objects
  • GL_NV_explicit_multisample
  • GL_NV_transform_feedback
  • Improved Thermal Settings reporting in nvidia-settings to accurately reflect hardware configurations with multiple thermal sensors.
  • Fixed an interaction problem between Compiz and 'screen-scraping' VNC servers like x11vnc and vino that caused the screen to stop updating. Fixes Launchpad bug #353126.
  • Enhanced VDPAU to add basic support for Xinerama. VDPAU will now operate on a single physical X screen under Xinerama. See the README for more details.
  • Enhanced VDPAU's handling of corrupt clips of all formats on GPUs with VDPAU feature set C to be at least as good as on GPUs with VDPAU feature set B. This significantly improves various clips provided by nvnews.net user eamiller.
  • Fixed a bug in Xv attribute handling that caused hue, saturation,brightness, and contrast values to be misapplied when using an Xv overlay adaptor.
  • Fixed a bug in the XvMC driver that prevented it from working on systems with AGP graphics cards.
  • Enhanced VDPAU to clear all VdpVideoSurfaces to black when allocated.This provides more consistent results when using a surface as a reference when no prior decode operation has written to that surface.In turn, this improves the results of decoding some corrupt streams,such as "p_only_no_play" from ffmpeg bug 1124.
  • Implemented new APIs to allow sharing VDPAU surfaces with OpenGL andCUDA. The OpenGL extension is GL_NV_vdpau_interop. For CUDA, please
  • see the documentation in the CUDA toolkit for details.
  • Worked around a bug where the combination of a GPU with VDPAU feature set A together with specific motherboard chipsets could cause visible corruption when decoding some MPEG-2 streams
  • Fixed a bug that prevented the VDPAU overlay-based presentation queue from being used more than a few hundred times per X server invocation.
  • Renamed the driver file libGLcore.so.VERSION to libnvidia-glcore.so.VERSION, as a small step towards reducing the filename collisions between NVIDIA's and MESA's OpenGL implementations.This driver file is used by NVIDIA's libGL.so and libglx.so, and should never be used directly by applications.
  • Changed the SONAME of libnvidia-glcore.so.VERSION,libnvidia-tls.so.VERSION, and libnvidia-compiler.so.VERSION to be ".so.VERSION", rather than ".so.1".These driver files are only used by other NVIDIA driver components, and are only intended to be usedby components of the matching NVIDIA driver version.
  • Removed the "-pkg#" suffix from the NVIDIA Linux .run files.The packages are now simply named "NVIDIA-Linux-ARCH-VERSION.run".On Linux-x86_64, a package which omits the 32-bit compatibility libraries is also available: "NVIDIA-Linux-x86_64-VERSION-no-compat32.run"
  • Simplified the directory structure of the Linux extracted package; most driver files are now just contained within the top level directory of the package.Pass the '--list' option to the .run file for details.
  • Removed precompiled kernel interfaces from the NVIDIA Linux-x86 .run file; these were ancient and had not been updated in years.Going forward, NVIDIA does not plan to provide precompiled kernel interfaces with the Linux .run files.However, nvidia-installer and the .run file will retain the ability for users to add their own precompiled kernel interfaces via the '--add-this-kernel' .run file option.
  • Compressed the nvidia-settings, nvidia-installer, and nvidia-xconfig tarballs with bzip2, rather than gzip.

New in Nvidia Linux Display Driver 32-bit 195.36.31 (Jun 21, 2010)

  • Fixed a problem with SLI SFR, AFR, and SLIAA modes with GeForce GTX 480 and GeForce GTX 470 and high-resolution display modes.

  • GeForce GTS 360M
  • Added support for NVIDIA 3D Vision Stereo on Linux with Quadro GPUs. See the "Stereo" X configuration documentation in the README
  • for details.
  • Fixed a bug that caused screen corruption after an application released a GLX_NV_present_video device.
  • Fixed an X server crash caused by starting nvidia-settings while X was not on the active VT.
  • Fixed brightness control hotkeys on some laptops.
  • Fixed an nvidia-settings bug that produced many "Bad argument" warning messages when running nvidia-settings --query all.
  • Fixed an installer bug that produced the following message:
  • WARNING: Unable to perform the runtime configuration check for library 'libGL.so.1' ('/usr/lib/libGL.so.195.36.03'); assuming successful installation.
  • Fixed a bug that caused G-Sync stereo synchronization to fail sometimes when enabling frame lock.
  • Fixed a bug that caused OpenGL applications to occasionally crash with "double free or corruption" messages when exiting.
  • On GPUs with VDPAU feature set A, enhanced VDPAU's handling of some corrupted or incorrectly formatted MPEG-1/2 streams. This solves a reported issue with "0testbad.mpg".
  • Fixed a bug in the VDPAU video mixer that caused chroma aberrations, and corruption in the right-hand few columns of pixels, when post- processing video surfaces with widths not an exact multiple of 4 pixels.
  • Fixed a bug that prevented the GPUFanControlState attribute from being set on the nvidia-settings command line.
  • Fixed a regression that made the "TVStandard" X configuration option cause system hangs with products from the GeForce 6 and 7 series.
  • Worked around a bug in some AUO laptop flat panels where the native mode in the EDID is invalid, leading to a 640x480 desktop repeated six times
  • across the screen.
  • Increased the maximum number of slices supported by VDPAU for MPEG-2 streams, in order to cope with the region 1 DVD "A Christmas Story".
  • Added unofficial preliminary support for xorg-server video driver ABI version 7, including xorg-server-1.7.99.2.
  • Fix the soname of libvdpau_nvidia.so.1 and libvdpau_trace.so.1 to match their filenames.
  • Fixed a performance regression with non-antialiased text in KDE4.
  • Enabled GPU acceleration for many RENDER compositing operations that were previously processed in software, including conjoint and disjoint blending
  • modes and component alpha blending.
  • Added experimental GPU acceleration of the RENDER CompositeTrapezoids operation. This can be enabled at runtime by running:
  • nvidia-settings -a AccelerateTrapezoids=1
  • This is only supported on the GeForce GTX series or newer products. Fixed a bug in the VDPAU overlay-based presentation queue that caused high CPU usage during "put bits" operations when more than two surfaces
  • were queued.
  • Updated `nvidia-settings --query all` to report all available attributes queryable through all NV-CONTROL target types.
  • Enhanced the VDPAU blit-based presentation queue to provide values of "first_presentation_time" that have less jitter.
  • Add support for R16F and RG32F GLXFBConfigs when using GeForce 8 series and higher GPUs.
  • Added support for A2BGR10 32-bit GLX visuals on 30-bit X screens. These allow some level of window transparency when using 30-bit visuals with GLX and Composite, but they may cause problems with older X servers and/or applications.ARGB GLX visuals can be disabled by adding:
  • Option "AddARGBGLXVisuals" "False" to the X configuration file.
  • Fixed a problem that caused DisplayPort devices to behave incorrectly when DPMS power saving mode was triggered.
  • Updated VDPAU to improve thread concurrency.See the README for details.
  • Altered NVIDIA X driver behavior in the case that no display devices are connected to the GPU.Previously, in this case, the NVIDIA X driver would pretend a CRT was connected to the GPU. Now, the NVIDIA X driver will not automatically pretend that any CRTs are connected.If the X driver does not detect any connected display devices, the X server will fail to start.
  • To restore the old behavior, use the ConnectedMonitor X configuration option; e.g.,
  • Option "ConnectedMonitor" "CRT"
  • Alternatively, if display is not desired, Quadro and Tesla GPU users can enable "NoScanout" mode, which bypasses any mode timing validation or use of display devices; this is configured with:
  • Option "UseDisplayDevice" "none"
  • Disabled software cursors when the driver is operating in "no scanout" (UseDisplayDevice "none") mode.The software cursor image is not visible in remote desktop applications or screenshots anyway, so having software cursor enabled was unnecessary.
  • Changed glXSwapBuffers() behavior for a pixmap such that it is now a no-op in the direct rendering case in order to match the indirect case and comply with the GLX spec. Previously, calling glXSwapBuffers() on pixmaps in the direct case would swap the pixmap's buffers if the pixmap was double buffered.
  • Modified the installation location and names of internal VDPAU libraries to conform to conventions and Debian packaging guidelines. New versions of libvdpau expect this layout. Compatibility with old versions of libvdpau is maintained with symlinks.
  • Fixed a bug that could cause errors in graphical applications run after a previous application using VDPAU and OpenGL. This behaviour was observed when running Gwenole Beauchesne's hwdecode-demos application.
  • Modified vdpau.h to increment VDPAU_VERSION, to reflect the fact that new features have been added in the past. Also, add the new define VDPAU_INTERFACE_VERSION.
  • Fixed a periodic temporary hang in the VDPAU blit-based presentation queue.
  • Fixed a problem that caused resolution limitations or corruption on certain DisplayPort devices such as the Apple 24" Cinema display or some DisplayPort to VGA adapters.
  • Disabled the UseEvents option for GeForce 8 series and higher GPUs due to a problem that causes occasional short hangs.It will be re-enabled when that bug has been tracked down and fixed.
  • VDPAU now allows multiple streams to be decoded at once, without the need to set any environment variables.

  • GeForce GT 220
  • GeForce G210
  • GeForce G210M
  • GeForce GT 230M
  • GeForce GT 240M
  • GeForce GTS 250M

  • Added support for OpenGL 3.2.
  • Updated the NVIDIA X driver to allow, on GeForce 8 or greater GPUs, more modes to validate on digital display devices whose EDIDs report very constrained HorizSync or VertRefresh ranges.
  • Fixed a randomly occurring X server crash caused by the PixmapCache option.
  • Increased the allowed amount of overscan compensation from 100 to 200.
  • On GPUs with VDPAU feature set B, VDPAU's handling of some corrupted or incorrectly formatted H.264 and MPEG streams has been improved.
  • Fixed a memory allocation problem with pre-GeForce 8 GPUs that caused GLX_EXT_texture_from_pixmap clients (e.g., Compiz, KDE 4) to display incorrect contents.
  • Added support for X.Org xserver 1.6.99.901 (also known as 1.7.0 RC1). Add a new OverscanCompensation NV-CONTROL attribute, available on GeForce 8 and higher. This option specifies the amount of overscan compensation to apply to the current mode. It is measured in raster pixels, i.e. pixels as specified in the current mode's backend timings.
  • Added GLX support for OpenGL 3.2 context profiles through the extension
  • GLX_ARB_create_context_profile.
  • Added support for IgnoreEDIDChecksum X configuration option, which can be used to force the X driver to accept the EDID of a display device even when the checksum is invalid. Please see the README IgnoreEDIDChecksum description for a caution and details of use.
  • Added support for configuring the GPU's fan speed; see the "Coolbits" X configuration option in the README.
  • Fixed a bug in VDPAU that could cause visible corruption near the bottom edge of the picture when decoding VC-1 simple/main profile clips whose heights are not exact multiples of 16 pixels, on GPUs with VDPAU feature set A.
  • On GPUs with VDPAU feature set C, VDPAU now supports decoding MPEG-4 Part 2, DivX 4, and DivX 5 video. The VDPAU API has been enhanced to expose this feature.
  • On GPUs with VDPAU feature set C, VDPAU now supports a higher quality video scaling algorithm. The VDPAU API has been enhanced to expose this feature.
  • Added code to reject screen modes based on available DisplayPort link bandwidth. Fixes display corruption caused by allowing high bandwidth modes on display devices that can't handle them, such as certain DisplayPort-to-VGA adapters that only support 2 DisplayPort lanes.
  • Fixed an initialization problem on some mobile GPUs.
  • Worked around X.Org X server Bugzilla bug #22804. This bug allows X clients to send invalid XGetImage requests to the hardware, leading to screen corruption or hangs. This was most commonly triggered by running JDownloader in KDE 4.
  • Fixed a crash in nvidia-settings displaying GPU information when in Xinerama.
  • Added GLX protocol support (i.e., for GLX indirect rendering) for the following OpenGL extensions:
  • GL_ARB_draw_buffers
  • GL_EXT_Cg_shader

  • GL_NV_parameter_buffer_object
  • GL_NV_vertex_program4
  • GLX protocol for GL_EXT_vertex_array was also updated to incorporate rendering using GL_ARB_vertex_buffer_object. Use of these extensions with GLX indirect rendering requires the AllowUnofficialGLXProtocol X configuration option and the __GL_ALLOW_UNOFFICIAL_PROTOCOL environment variable.
  • Fixed glXQueryVersion to report GLX version 1.4. NVIDIA's GLX version has been 1.4 for several releases, and was already reported as 1.4 in the GLX client and GLX server version strings.
  • Fixed a problem that caused window border corruption when the screen is rotated.
  • Added support for configuring the GPU PowerMizer Mode on GeForce 8 or later GPUs with multiple performance levels via nvidia-settings and NV-CONTROL.
  • Added support for NVIDIA Quadro SDI Capture, part of the Quadro Digital Video Pipeline.
  • Updated nvidia-installer to detect newer Debian distributions that use /usr/lib32 instead of /emul/ia32-linux as the 32-bit library path.

New in Nvidia Linux Display Driver 32-bit 185.18.36 (Aug 24, 2009)

  • Fixed a bug that caused kernel panics when starting X on some mobile GPUs.
  • Fixed an interaction problem between VDPAU and PowerMizer when using VDPAU solely as a display mechanism, and not to decode video streams. The GPU performance level should now be raised, if required, in this scenario.
  • Fixed VDPAU to avoid "display preemption" in some cases where a VdpOutputSurface is deleted while it is still active (either queued or visible) in a VdpPresentationQueue. In particular, this can occur in MPlayer when using the "-fs" option, and could completely prevent VDPAU from operating successfully, depending on the exact timing conditions.

New in Nvidia Linux Display Driver 32-bit 185.18.31 (Aug 13, 2009)

  • Added code to forcibly terminate long-running CUDA kernels when Ctrl-C is pressed.
  • Fixed a bug that could cause occasional memory corruption problems or segmentation faults when running OpenGL applications on Quadro GPUs.
  • Fixed a deadlock in the OpenGL library that could be triggered in certain rare circumstances on Quadro GPUs.
  • Fixed an interaction problem between PowerMizer and CUDA applications that caused the performance level to be reduced while the CUDA kernel is running.
  • Made CUDA compute-exclusive mode persistent across GPU resets.
  • Fixed the order of outputs in the GPUScaling nvidia-settings property.
  • Fixed a bug that caused graphics corruption in some OpenGL applications when the Unified Back Buffer is enabled the application window is moved.
  • Fixed a bug that caused glXGetVideoSyncSGI, glXWaitVideoSyncSGI, and glXGetRefreshRateSGI to operate on the wrong screen when there are multiple X screens.
  • Fixed a bug that causes corruption or GPU errors when an application paints a redirected window whose background is set to ParentRelative on X.Org servers older than 1.5. This was typically triggered by running Kopete while using Compiz or Beryl.
  • Fixed a bug in VDPAU that could cause visible corruption when decoding H.264 clips with alternating frame/field coded reference pictures, and a video surface is concurrently removed from the DPB, and re-used as the decode target, in a single decode operation. This affected all GPUs supported by VDPAU.
  • Fixed a bug in VDPAU that could cause visible corruption near the bottom edge of the picture when decoding VC-1 advanced profile clips whose heights are not exact multiples of 16 pixels, on G98 and MCP7x (IGP) GPUs.
  • Enhanced VDPAU to better handle corrupt/invalid H.264 bitstreams on G84, G86, G92, G94, G96, or GT200 GPUs. This should prevent most cases of "display preemption" that are caused by bitstream errors.
  • Fixed an X server crash when using the VDPAU overlay-based presentation queue and VT-switching away from the X server.
  • Enhanced VDPAU's detection of the GPU's video decode capabilities.
  • Fixed a bug in VDPAU that could cause ghosting/flashing issues when decoding H.264 clips, in certain full DPB scenarios, on G98 and MCP7x.
  • Fixed VDPAU to detect an attempt to destroy the VdpDevice object when other device-owned objects still exist. VDPAU now triggers "display preemption", and returns an error, when this occurs.
  • Enhanced VDPAU's error handling and resource management in presentation queue creation and operation. This change correctly propagates all errors back to the client application, and avoids some resource leaks.

New in Nvidia Linux Display Driver 32-bit 185.18.29 (Jul 29, 2009)

  • Fixed the behavior of the NV_CTRL_FRAMELOCK_SYNC_DELAY NV-CONTROL attribute on Quadro G-Sync II.
  • Fixed a problem with Quadro SDI where transitioning from "clone mode" to "OpenGL mode" would fail.
  • Fixed VDPAU to eliminate some cases of corruption when decoding H.264 video containing field-coded reference frames on G84, G86, G92, G94, G96, or GT200 GPUs. Such streams are commonly found in DVB broadcasts.
  • Slightly improved the performance of the VDPAU noise reduction algorithm.
  • Enhanced VDPAU to validate whether overlay usage is supported by the current hardware configuration, and to automatically fall back to the blit-based presentation queue if required.
  • Fixed error checking in VdpVideoMixerRender, to reject calls that specify more layers than the VdpMixer was created with.
  • Modified VDPAU's VDPAU_DEBUG code to emit a complete backtrace on all platforms, not just on 32-bit Linux.
  • Improved interaction between VDPAU and PowerMizer; appropriate performance levels should now be chosen for video playback of all standard resolutions on all supported GPUs.
  • Fixed a bug in VDPAU that sometimes caused "display preemption" when the VdpDecoderCreate function failed.
  • Fixed a potential segfault in the VDPAU trace library, triggered by a multi-threaded application creating a new VdpDevice in one thread, at the same time that another thread detected "display preemption".

New in Nvidia Linux Display Driver 32-bit 180.60 (Jun 1, 2009)

  • Fixed stability problems with some GeForce 6200/7200/7300 GPUs on multi-core/SMP systems.
