Here's one thing to try: Run (as root) "lspci -v" and find what the
system thinks your video controller is.  Years ago I had a problem with
the system wrongly detecting the video chipset for my Radeon card.
(Though no one seemed to acknowledge the problem I repeatedly reported,
still I would have thought they would have it fixed by now.)  I was able
to fix it just by changing one line in some file I can't remember right
now and then doing radical surgery on my xorg.conf file.
