Slow logout with Gnome, FC3

[Greg Trounson]

Gidday,

I have a clean FC3 install here on an Athlon64 with an ATi Radeon (using 
standard 'radeon' driver).  Most operations are nice and fast, except 
for logging out of Gnome.

When I select "log out" and confirm, I'm dropped back to the desktop 
which I can no longer interact with, and can only watch while the system 
takes two minutes before bringing me back to the login screen.  I can 
CTRL_ALT_BKSPACE to kill X, and I can CTRL_ALT_F1 to a terminal during 
this time.

To state the obvious, memory usage is well below full, no disk activity 
occurs, and CPU usage is below 10% so it's not actually waiting on any 
machine resources.

Has anyone else had this problem?

thanks,
Greg
