* 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 * 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=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 * 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.­
