I'm running Fedora 16 on a Lenovo Thinkpad X61. Gnome 3 has been working just fine for months, but crashed out on me all of a sudden just a little while ago. Rebooted in fallback mode.
This happened before with this computer while running Ubuntu.
I recently installed GIMP and a bunch of dependencies, which is the only think I can think of that would have caused this. Sadly, I can't remember what would have caused the crash the last time around.
Relevant line of lspci output:
00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (primary) (rev 0c)
Any help is greatly appreciated.
