New in version 346.16 Beta

November 13th, 2014
  • Added support for the following GPUs:
  • GeForce GTX 970M
  • GeForce GTX 980M
  • 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.
  • Added support for decoding VP8 video streams using the NVCUVID API on GPUs with VP8 hardware decode support.
  • Added support for the following EGL extensions:
  • 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.
  • 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.

New in version 343.13 Beta (August 6th, 2014)

  • Fixed a bug that caused disabled displays to be implicitly included in the target selection for some queries and assignments on the nvidia-settings command line interface, in the absence of any explicit target selection.
  • Added a new attribute to the NV-CONTROL API to query the current utilization of the video decode engine.
  • Fixed a bug where the Exchange Stereo Eyes setting in nvidia-settings didn't work in certain stereo configurations.
  • Worked around a Unigine Heaven 3.0 shader bug which could cause corruption when tessellation is enabled by implementing an application profile that uses the "GLIgnoreGLSLExtReqs" setting. See the documentation for the __GL_IGNORE_GLSL_EXT_REQS environment variable for more details.
  • Fixed a memory leak when destroying EGL surfaces.
  • Added support for multiple simultaneous EGL displays.
  • Removed support for G8x, G9x, and GT2xx GPUs, and motherboard chipsets based on them. Ongoing support for new Linux kernels and X servers, as well as fixes for critical bugs, will be included in 340.* legacy releases through the end of 2019.
  • Fixed a bug that could cause nvidia-installer to unsuccessfully attempt to delete the directory containing precompiled kernel module interfaces, on packages prepared with --add-this-kernel.
  • Updated nvidia-installer to log uninstallation to a separate file from the installation log, and to attempt uninstalling previous driver installations using the installer program from the previous installation, when available.

New in version 340.17 Beta (June 9th, 2014)

  • Made various improvements and corrections to the information reported to GL applications via the KHR_debug and ARB_debug_output extensions.
  • Fixed a bug that caused GLX applications which simultaneously create drawables on multiple X servers to crash when swapping buffers.
  • Updated nvidia-settings to report all valid names for each target when querying target types, e.g. `nvidia-settings -q gpus`.
  • Added support for controlling the availability of Fast Approximate Antialiasing (FXAA) on a per-application basis via the new __GL_ALLOW_FXAA_USAGE environment variable and the corresponding GLAllowFXAAUsage application profile key. See the README for details.
  • Fixed a bug where indirect rendering could become corrupted on system configurations that disallow writing to executable memory.
  • Updated the nvidia-settings Makefiles to allow nvidia-settings to be dynamically linked against the host system's libjansson. This option can be enabled by setting the NV_USE_BUNDLED_LIBJANSSON Makefile variable to 0. Please note that nvidia-settings requires libjansson version 2.2 or later.
  • Added initial support for G-SYNC monitors. Additional details and system requirements can be found at: http://www.geforce.com/hardware/technology/g-sync
  • Fixed an X driver bug that caused gamma ramp updates of the green channel at depth 15, on some recent GPUs, to be ignored.

New in version 337.19 Beta (May 6th, 2014)

  • Fixed a bug causing mode validation to fail for 4K resolutions over HDMI in certain situations.
  • Added nvidia-settings command line controls for over- and under-clocking attributes. Please see the nvidia-settings(1) manual page for more details.
  • Fixed several cosmetic issues in the clock control user interface of nvidia-settings.
  • Added support for the GLX_EXT_stereo_tree extension. For more details, see the extension specification:
  • http://www.opengl.org/registry/specs/EXT/glx_stereo_tree.txt
  • Enabled support for using Unified Back Buffer (UBB) and 3D Stereo with the composite extension on Quadro cards. Using stereo with a composite manager requires a stereo-aware composite manager. Otherwise, only the left eye of stereo applications will be displayed. See the GLX_EXT_stereo_tree extension specification for more details.

New in version 337.12 Beta (April 8th, 2014)

  • Added support for the following GPUs:
  • GeForce 830M
  • GeForce 840M
  • GeForce 845M
  • GeForce GTX 850M
  • GeForce GTX 860M
  • GeForce GTX 870M
  • GeForce GTX 880M
  • GeForce GT 705
  • GeForce GT 720
  • Fixed a bug that could cause OpenGL programs to freeze under some low memory conditions.
  • Updated the display configuration page in nvidia-settings to uniquely identify DisplayPort 1.2 monitors by displaying the monitor GUIDs.
  • Fixed a bug that could cause ECC settings to be displayed incorrectly in nvidia-settings when changing ECC settings on a multi-GPU system.
  • Removed the "OnDemandVBlankInterrupts" X configuration option: this option has been enabled by default since version 177.68 of the NVIDIA Unix driver, and the documentation had not been updated to reflect the new default value.
  • Fixed a bug that caused GPU errors when hotplugging daisy-chained DisplayPort 1.2 displays.
  • Updated the color correction settings page in the nvidia-settings control panel to reflect gamma changes made by other RandR clients while the control panel was already running.
  • Fixed a bug that prevented the use of multiple simultaneous X servers on UEFI systems.
  • Updated the nvidia-settings source package to build libXNVCtrl when building nvidia-settings, instead of relying on a pre-built library.
  • Added the ability to over- and under-clock certain GeForce GPUs in the GeForce GTX 400 series and later. For GPUs that allow it, an offset can be applied to clock values in some clock domains of some 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.
  • Updated the minimum required version of GTK+ from 2.2 to 2.4 for nvidia-settings.
  • Renamed the RandR output property _GUID to GUID now that it is an official property documented in randrproto.txt:
  • http://cgit.freedesktop.org/xorg/proto/randrproto/commit/?id=19fc4c5a72eb9919d720ad66734029d9f8e313b1
  • Reduced CPU utilization and GPU memory utilization of the NVIDIA EGL driver.
  • Added support for the following EGL extensions:
  • - EGL_EXT_buffer_age;
  • - EGL_EXT_client_extensions;
  • - EGL_EXT_platform_base;
  • - EGL_EXT_platform_x11.
  • Renamed the "Clone" setting of the "MetaModeOrientation" X configuration option to "SamePositionAs", to make clear that this setting applies to the position only, and not to the resolution of modes in the MetaMode.
  • Added NV-CONTROL attribute NV_CTRL_VIDEO_ENCODER_UTILIZATION to query utilization percentage of the video encoder engine.
  • Added support for the GLX_NV_delay_before_swap extension. For more details, see the extension specification:
  • http://www.opengl.org/registry/specs/NV/glx_delay_before_swap.txt
  • Report correct buffer sizes for RGB GLX visuals, GLXFBConfigs, and EGLConfigs. Previously, RGB10 and RGB8 formats were reported as having 32 bits, and RGB5 formats were reported as having 16 bits. Now they are correctly reported as 30, 24, and 15 bit formats respectively as required by the GLX and EGL specifications.

New in version 334.16 Beta (February 7th, 2014)

  • Fixed a bug that could cause nvidia-settings to compute incorrect gamma ramps when adjusting the color correction sliders.
  • Updated the nvidia-settings control panel to allow the selection of display devices using RandR and target ID names when making queries targeted towards specific display devices.
  • Fixed a bug that prevented some dropdown menus in the nvidia-settings control panel from working correctly on older versions of GTK+ (e.g. 2.10.x).
  • Updated the nvidia-settings control panel to provide help text for application profile keys and suggestions for valid key names when configuring application profiles.
  • Updated the nvidia-settings control panel to populate the dropdown menu of stereo modes with only those modes which are available.
  • Fixed a bug that could cause applications using the OpenGL extension ARB_query_buffer_object to crash under Xinerama.
  • Fixed a bug that caused high pixelclock HDMI modes (e.g. as used with 4K resolutions) to be erroneously reported as dual-link in the nvidia-settings control panel.
  • Fixed a bug that prevented some DisplayPort 1.2 displays from being properly restored after a VT switch.
  • Renamed per GPU proc directories in /proc/driver/nvidia/gpus/ with GPU's bus location represented in "domain:bus:device.function" format.
  • Added 64-bit EGL and OpenGL ES libraries to 64-bit driver prackages.
  • Changed format of "Bus Location" field reported in the /proc/driver/nvidia/gpus/0..N/information files from "domain:bus.device.function" to "domain:bus:device.function" to match the lspci format.
  • Fixed a bug in the GLX_EXT_buffer_age extension where incorrect ages would be returned unless triple buffering was enabled.
  • Changed the driver's default behavior to stop deleting RandR 1.2 outputs corresponding to unused DisplayPort 1.2 devices. Deleting these outputs can confuse some applications. Added a new option, DeleteUnusedDP12Displays, which can be used to turn this behavior back on. This option can be enabled by running sudo nvidia-xconfig --delete-unused-dp12-displays
  • Improved support for the __GL_SYNC_DISPLAY_DEVICE and VDPAU_NVIDIA_SYNC_DISPLAY_DEVICE environment variables in certain configurations. Both environment variables will now recognize all supported display device names. See "Appendix C. Display Device Names" and "Appendix G. VDPAU Support" in the README for more details.
  • Improved performance of the X driver when handling large numbers of surface allocations.
  • Fixed a bug that caused PBO downloads of cube map faces to retrieve incorrect data.
  • Added experimental support for ARGB GLX visuals when Xinerama and Composite are enabled at the same time on X.Org xserver 1.15.

New in version 331.17 Beta (October 25th, 2013)

  • Fixed a bug that prevented configuration files containing application profiles from being loaded when directories were present in the application profile configuration search path.
  • Deferred initialization of libselinux in the NVIDIA OpenGL driver, in order to avoid a problem where libselinux might not be ready when the NVIDIA libGL shared library is first loaded.
  • Fixed a bug that could lead to memory exhaustion in OpenGL applications running on 32-bit systems.
  • Added nvidia-uvm.ko, the NVIDIA Unified Memory kernel module, to the NVIDIA Linux driver package. This kernel module provides support for the new Unified Memory feature in an upcoming CUDA release.

New in version 331.13 Beta (October 4th, 2013)

  • Fixed a bug that caused the X server to fail to initialize when DisplayPort 1.2 monitors were assigned to separate X screens on the same GPU.
  • Fixed a bug that could cause a deadlock when forking from OpenGL programs which use some malloc implementations, such as TCMalloc.
  • Fixed a bug that prevented Warp & Blend settings from being retained across display configuration changes.
  • Fixed a bug that prevented some settings changes made via the nvidia-settings command line interface from being reflected in the nvidia-settings graphical user interface.
  • Changed the clipping behavior of the NVIDIA X driver on Trapezoids and Triangles for some RENDER operations to match the behavior in newer versions of Pixman:
  • http://lists.freedesktop.org/archives/pixman/2013-April/002755.html
  • Fixed a bug in MetaMode tracking that could cause spurious error messages to be printed when attempting to add or delete Metamodes via NV-CONTROL.
  • Fixed a bug that caused the NVIDIA X driver to attempt to load the X11 "shadow" module unconditionally, even in situations where the driver had no need to use the module. This could result in the printing of spurious error messages, on X servers where the module was not present.
  • Fixed a bug that prevented display configuration changes made with xvidtune(1) from working correctly.
  • Fixed a bug that occasionally caused display corruption in GLX applications while changing the display configuration.
  • Fixed a bug that prevented glReadPixels from working correctly when reading from Pixel Buffer Objects over indirect rendering, when the image width is not a multiple of 4.
  • Added a new NV-CONTROL attribute, NV_CTRL_BACKLIGHT_BRIGHTNESS, for controlling backlight brightness.
  • Fixed a bug that prevented nvidia-settings from creating display device configuration pages for newly connected DisplayPort 1.2 Multi Stream Transport downstream devices.
  • Added GPU utilization reporting to the nvidia-settings control panel.
  • Fixed a bug in the nvidia-settings control panel that prevented users from configuring stereo, when stereo was not already configured.
  • Added support for reporting the tachometer-measured fan speed on capable graphics boards via nvidia-settings and the NV-CONTROL API. The preexisting mechanism for reporting fan speed reports the speed of the fan as programmed by the driver. 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/

New in version 325.15 Beta (August 6th, 2013)

  • Added support for the following GPUs:
  • GRID K340
  • GRID K350
  • NVS 315
  • Quadro K500M
  • Fixed a bug in the nvidia-settings control panel that could cause spurious messages about layout inconsistencies to be printed when changing the display layout while SLI is enabled.
  • Fixed a bug that could cause display flickering after setting some scaling configurations.
  • Fixed a bug that prevented the status bar on the "PowerMizer" and "X Server XVideo Settings" pages in the nvidia-settings control panel from being updated when settings were changed by another NV-CONTROL client.
  • Fixed a bug that could cause some UI elements to be duplicated in the nvidia-settings control panel following a VT switch on X server configurations with multiple NVIDIA X screens.
  • Changed the default PCIe interrupt delivery method from virtual-wire to MSI. Note that if the NVIDIA Linux driver fails to initialize with an error indicating that it is not receiving interrupts, MSI can be disabled by setting the module parameter "NVreg_EnableMSI=0" when loading the NVIDIA kernel module.
  • Removed support for Linux 2.4 kernels. The NVIDIA Linux driver now requires Linux 2.6.9 or later.
  • Fixed a bug that prevented the creation of a mode via RandR with the same name as a previously created mode, even after the previous mode had been deleted.
  • Fixed a bug in nvidia-settings that caused GTK+ theme colors to be ignored for some UI elements.
  • Fixed a bug that caused nvidia-settings to write hostname-based color correction settings to the .nvidia-settings-rc configuration file, even when the "Include X Display Names in the Config File" option was unset. This could lead to a long delay when starting nvidia-settings, if a hostname saved to the configuration file failed to resolve.
  • Fixed a bug that exposed edge overlap controls on the SLI Mosai page of nvidia-settings on edges where overlap was impossible.
  • Fixed a bug that caused some settings in the nvidia-settings control panel to be reset when reprobing displays.
  • Fixed a bug that could cause OpenGL applications that use Frame Buffer Objects (FBOs) to crash following a mode switch (e.g. changing the resolution of a display or transforming it).
  • Fixed a memory leak that could be triggered by unloading libGL before destroying all GLX contexts.
  • Fixed a bug that could cause color correction settings to be applied to the wrong display when multiple displays are unplugged and then plugged back in again.
  • Fixed a bug that could cause a spurious error message about a missing NV-GLX extension when performing indirect rendering from a GLX client with the NVIDIA client-side OpenGL libraries to a non-NVIDIA GLX server.
  • Fixed an OpenGL bug that prevented conditional rendering from the NV_conditional_render extension from correctly affecting CopyPixels.
  • Improved the rendering performance of complex gradients.
  • Added support for configuring SLI Mosaic and Base Mosaic in the "X Server Display Configuration" page of nvidia-settings.
  • Updated nvidia-installer to look for the following files:
  • /usr/lib/nvidia/alternate-install-available
  • /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 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.
