Couple of older desktop machines having Wolfdale (Core2Duo)  and Intel
G33 chipsets still show the following -

─[$] vainfo

libva info: VA-API version 0.39.4
libva info: va_getDriverName() returns 0
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/i915_drv_video.so
libva info: va_openDriver() returns -1
vaInitialize failed with error code -1 (unknown libva error),exit

Double-checked for any nvidia bits but didn't find any. Maybe I should
file a separate bug report for the desktop machines ? Please let me
know what I should do ?
