NV graphics card Linux Driver Upgrade version 185.18.31 -- Linux general technology-Linux technology and application information, the following is read details. NVIDIA recently updated drivers for Linux systems frequently. In July 29th day of last month, the driver for version 185.18.29 was released, and today it is updated again. The new driver version is 185.18.31, which mainly fixes some new bugs.
The new driver version fixes some new bugs based on the previous version. Among them, Items 13 to 16 are newly added. The updates are as follows:
1. Added some code to forcibly terminate the long-running CUDA kernel when pressing Ctrl-C.
2. Fixed a bug that was characterized by occasional memory crashes or segmentation errors when running OpenGL applications on Quadro GPU.
3. Fixed a deadlock in the OpenGL library. On Quadro GPU, this deadlock may be triggered in rare cases.
4. Fixed an issue of interaction between PowerMizer and CUDA applications. This problem can cause performance degradation when running the CUDA kernel.
5. The CUDA computing exclusive mode remains valid throughout the GPU reset period.
6. corrected the output sequence in the GPUScaling nvidia-settings attribute.
7. Fixed a bug. This bug is characterized by graphic crashes in some OpenGL applications when Unified Back Buffer and mobile application windows are enabled.
8. Fixed a bug in which glXGetVideoSyncSGI, glXWaitVideoSyncSGI, and glXGetRefreshRateSGI work on the wrong screen when multiple X screens exist.
9. Fixed a bug. The bug is characterized by the coloring of the redirection window by the application (the background of the window is earlier than version 1.5 X. is set to ParentRelative on the Org server), can cause a crash or GPU error. When Compiz or Beryl is used, running Kopete usually triggers this bug.
10. Fixed a bug in VDPAU. The feature of this bug is to use the reference image of alternate frame/field encoding for H. when 264 clips are decoded, and a video surface is deleted from DPB in a single decoding operation, and then used as the decoding target again, this can cause a visual crash. This bug affects all GPUs supported by VDPAU.
11. Fixed a bug in VDPAU that features Advanced Profile for VC-1 on G98 and MCP7x (IGP) GPUs that are not 16 pixel Integers) when decoding a clip, it may cause a visual crash in the area near the bottom of the image.
12. Enhanced VDPAU so that it can better handle corrupted/invalid H.264 bit streams on G84, G86, G92, G94, G96, or GT200 GPUs. This will prevent most Display Preemption situations caused by bit stream errors.
13. fixed the problem of X server crash when the presentation Queue Based on the VDPAU stack and VT-switching not close to the X server. Enhanced detection of GPU (graphics processor) video decoding capabilities by VDPAU.
14. Fixed a bug in VDPAU, which is characterized by G98 and MCP7x pair H. during Decoding of 264 fragments, duplicate shadows/flashes may occur in some fully DPB scenarios.
15. Fixed a problem. This problem is characterized by the threat that VDPAU detects whether the VdpDevice object is damaged when other device objects exist. In this case, VDPAU can now trigger "Display Preemption" and return an error value.
16. Enhanced Fault Handling and resource management capabilities of VDPAU during creation and operation of presentation queues. This improvement can correctly return all errors to the client application to avoid some resource loss.
