[Intel-gfx] [ASK] How can I set the X to select the DRI driver i965

[熊]

Hi All, 
  
       I am working for video accelerating for intel card (945GM), but the driver can not run well. Please help me .
  
      1. vainfo 
            libva info: VA-API version 0.33.0
            libva info: va_getDriverName() returns 0
           libva info: Trying to open /usr/lib/dri/i915_drv_video.so
           libva info: va_openDriver() returns -1
           vaInitialize failed with error code -1 (unknown libva error),exit
  
            of course I know the reseon of this error, because there is no i915_drv_video.so in the path. but there is i965_drv_video.so in the path.
            I have read the code of libva, i know it get the driver name by getting the dri driver name, which is in the following.
        2.  xorg.0.log
             [    44.095] (==) Depth 24 pixmap format is 32 bpp
            [    44.096] (II) intel(0): [DRI2] Setup complete
            [    44.096] (II) intel(0): [DRI2]   DRI driver: i915
            [    44.096] (II) intel(0): Allocated new frame buffer 1408x768 stride 8192, tiled

             So, I hope X-server can load i965 as  DRI driver, and i965_dri.so is in the /usr/lib/dri.
  
  
      Please help me .
  
  
 Tks && Best Regards.
