Additional information
  • Added GLX protocol support (i.e., for GLX indirect rendering) for the following OpenGL extensions:
      • GL_ARB_draw_buffers
      GL_EXT_Cg_shader
      GL_EXT_gpu_program_parameters
      GL_NV_fragment_program
      GL_NV_gpu_program4
      GL_NV_register_combiners
      GL_NV_vertex_program1_1
      GL_NV_vertex_program2
  • Added unofficial GLX protocol support (i.e., for GLX indirect rendering) for the following OpenGL extensions:
      • GL_ARB_geometry_shader4
      GL_ARB_shader_objects
      GL_ARB_texture_buffer_object
      GL_ARB_vertex_buffer_object
      GL_ARB_vertex_shader
      GL_EXT_bindable_uniform
      GL_EXT_compiled_vertex_array
      GL_EXT_geometry_shader4
      GL_EXT_gpu_shader4
      GL_EXT_texture_buffer_object
      GL_NV_geometry_program4
      GL_NV_vertex_program
      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 a bug that caused glXGetVideoSyncSGI, glXWaitVideoSyncSGI, and glXGetRefreshRateSGI to operate on the wrong screen when there are multiple X screens.
  • 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.
  • 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.
  • Added support for configuring the GPU PowerMizer Mode on GeForce 8 or later GPUs with multiple performance levels via nvidia-settings and NV-CONTROL.
  • 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 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.
