Hmm...just for the record, I think you can forget the last one. I've
mostly worked with Nvidia, where the permissions problem arises from the
fact that if person A logs into X, then logs out, he or she usually
leaves a few processes behind (gconfd and/or kdeinit), so that the next
person who logs in won't get ownership of /dev/nvidia*. This does not
happen with proper DRI drivers such as the XFree ATI ones, since X
manages the permssions of /dev/dri/* based on Section "DRI" in XF86Config.
Anyway, just thought I'd mention that. Another possibility would of
course be that another user was simultaneously logged into X, using
another server.
