Failed to open VDPAU backend libvdpau_i965.so

Some packages have been giving me these and similar messages, irking me for a while now.

Failed to open VDPAU backend libvdpau_i965.so: cannot open shared object file: No such file or directory

I think I found a solution, which is not really a solution as I don't understand why vdpau should be called for i965.

Install the following packages:

libva-intel-driver
libvdpau-va-gl

Set the following environment variable:

VDPAU_DRIVER=va_gl

Alternatively, you could create a symlink instead of the environment variable.

# cd /usr/lib/vdpau/
# ln -s libvdpau_va_gl.so.1 libvdpau_i965.so.1

But this litters the system. I would rather set the environment variables for all users, if so required.
