Been happily be using FC12 for roughly 6 months.
I installed 2 image browser apps to view all my Photos.
After I rebooted the GDM login screen hung, unable to login to X.
So I changed runtime level 3.
The ATi driver that came with FC12 worked fine and the driver from AMD do not support my kernel. I don't do system updates.
Anyway to restore the original driver that was provided with the FC12 disc? Possibly corrupt.
