Operating System: Linux x86
Release Date: July 31, 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
- 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
- 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)
- 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.
