I had this problem also.  If I remember correctly it is a known error
with ppc udev and gnome.  Anyways to fix it this is what I did.

Add this line:

pmu:root:video:0660

to /etc/udev/permissions.d/udev.permissions

Then make sure your user is in the video group.  Hope this fixes your
problems.  Good luck.
