Fedora Locks Up on Logout

[Steve Strong]

I've installed Fedora 2 on a system that has been running Redhat 9.0. 
When I log off, the system hangs, the monitor displays a message
complaining that the refresh rate is out of range.  

The X configuration has the correct monitor and video card with all of
the same configuration data for the RH 9.0 machine right next to it.

Any ideas?
