  • 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.

  • 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.

  • 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".

New in version 310.44 (April 2nd, 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 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.

  • 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.

  • 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 version 302.17 (June 16th, 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.

  • Implemented color depth 30 (10 bits per component) support for GeForce 8 series and higher GPUs.
  • Implemented support for constraining cursors to the visible regions of connected displays; see the "ConstrainCursor" X Option in the README for details.

New in version 290.10 (November 22nd, 2011)

  • Added support for the following GPU:
  • GeForce GTX 460 SE v2
  • Improved the performance of FBO bind operations when using Xinerama by ~30% in some cases.

  • 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. Added the __GL_SHADER_DISK_CACHE and __GL_SHADER_DISK_CACHE_PATH environment variables for further configuration. See the README for further details.
  • Added GLX protocol support (i.e., for GLX indirect rendering) for the following OpenGL extension:

  • Added support for hardware button based pairing to NVIDIA 3D Vision Pro. Single click button on the hub to enter into a pairing mode which pairs one pair of glasses at a time. Double click the same button on the hub to enter into a pairing mode which pairs multiple pairs of glasses at a time.
  • Added unofficial GLX protocol support (i.e., for GLX indirect rendering) for the following OpenGL extensions:
  • GL_NV_framebuffer_multisample_coverage
  • GL_NV_texture_barrier
  • Added GLX protocol support (i.e., for GLX indirect rendering) for the following OpenGL extension:

  • Fixed a bug that caused corruption on the menus in OpenOffice.org when the screen is rotated.
  • Fixed a bug that caused Java2D widgets to disappear when Java is configured to render using FBOs.
  • Added a new X configuration option "BaseMosaic" which can be used to extend a single X screen transparently across all of the available display outputs on each GPU. See "Appendix B. X Config Options" in the README for more information.

New in version 270.41.19 (May 22nd, 2011)

  • 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.
  • Added unofficial GLX protocol support (i.e., for GLX indirect rendering) for the following OpenGL extensions:
  • GL_ARB_shader_subroutine
  • GL_ARB_map_buffer_range
  • Added GLX protocol support (i.e., for GLX indirect rendering)for the following OpenGL extensions:
  • 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 version 260.19.44 (March 9th, 2011)

  • Updated the NVIDIA X driver to not update mode timings for G-Sync compatibility when NVIDIA 3D Vision or NVIDIA 3D VisionPro isenabled along with a G-Sync device.

New in version 260.19.36 (January 21st, 2011)

  • 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 version 256.35 (June 24th, 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

  • Enhanced VDPAU to add basic support for Xinerama. VDPAU will now operate on a single physical X screen under Xinerama. See theREADME 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 and CUDA. 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.
  • Compressed the nvidia-settings, nvidia-installer, and nvidia-xconfig tarballs with bzip2, rather than gzip.

New in version 195.36.31 (June 21st, 2010)

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

New in version 195.36.15 (March 19th, 2010)

  • Fixed a regression that caused the driver to fail to properly adjustthe GPU fan speed on some GPUs.
  • Fixed a bug that prevented performance level transitions on recentGPUs with SDDR3 and GDDR5 memory.
  • Added support for the following GPUs:
  • Quadro FX 880M
  • GeForce GTS 350M
  • GeForce GTS 360M
  • 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 an nvidia-settings bug that produced many "Bad argument" warning messages when running nvidia-settings --query all.
  • 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.

New in version 190.53 (December 17th, 2009)

  • 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.

New in version 185.18.36 (August 24th, 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 version 185.18.31 (August 13th, 2009)

  • Fixed a bug that could cause occasional memory corruption problems or segmentation faults when running OpenGL applications on Quadro GPUs.

  • 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 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.
  • Fixed an installer problem that prevented Linux ABI compatibility from working with newer versions of FreeBSD.

New in version 185.18.29 (July 29th, 2009)

  • Fixed a bug that could cause occasional memory corruption problems or segmentation faults when running OpenGL applications on Quadro GPUs.

  • Added support for new horizontal interlaced and checkerboard passive stereo modes.
  • Fixed a DisplayPort interaction problem with power management suspend/resume events.
  • Fixed occasional X driver memory management performance problems when a composite manager is running.

  • 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".
