Talk:Hardware video acceleration
This variable may need to be set when using older AMD cards even with open source drivers. I fixed this by adding a simlink in
/usr/lib/dri/r300_drv_video.so --> vdapu_video.so but this may have been able to be fixed with this environmental variable. It seems to work alright and doesn't break anything with my old backup laptop but this is probably not a preferred solution.
