Do all of these machines have nVidia graphics cards? Just a thought, but there's a known issue with the new Xorg 1.9 ABI that breaks the older nVidia drivers, and I'm guessing the 6800 would be one of them, hence the reason that Ubuntu *thinks* it is running ok. That might also explain the fact that there is no X fallback coming up.
Kernel modesetting commands anyone? I remember seeing something about a machine with SiS graphics...I had trouble with them too :( -- Roy Jamison (xteejx) Ubuntu Bug Squad Ubuntu Bug Control www.ubuntu.com -- [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.com/UKTeam/
