Re: cannot see 7300 LE DVI output in Debian, ok in Fedora
According to your bug report, you're not using the F7 BIOS, but rather F2.
When X is hung, are you able to ssh to the system and generate a bug report?
However, the fact that this works in FC, and not Mandriva or Debian suggests that this is a kernel or Xorg bug. Can you isolate whether the problem persists (or appears) with a recent kernel.org kernel in FC & Debian?
