VDPAU_DRIVER Variable

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.

The Hardware_video_acceleration#Configuring_VDPAU section says:
"For the open source AMD/ATI driver set it to the proper driver version depending on your GPU (see below)."
So yes, you should have set the VDPAU_DRIVER variable instead of creating the symlink.

Yes, I probably should change it but I had that as a solution before finding that info in the wiki. I bring this up because it seemed to be indicated that that information may be unnecessary for open source AMD drivers. Maybe it isn't needed for newer AMD cards? The above example is from a laptop which is at least 11 years old this summer. Anyway, I still think that information is useful to keep in the wiki.

I've been thinking about swapping Configuring and Verifying for exactly this reason, but the problem is that I don't know when it is needed to set the the variable, it seems to very from system to system.
