Linux Display Driver Version 195.36.15
- Fixed a bug that caused the X server to crash when renderingoccurred while the X server was not on the active VT.
- 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
- Added support for NVIDIA 3D Vision Stereo on Linux with Quadro GPUs. See the "Stereo" X configuration documentation in the README
- 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-184.108.40.206.
- 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=1This 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
- 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.
