X Hangs on FC1 install

[Mark Heslep]

This appears to be  dual head radeon related problem:

Attempted a clean FC 1 install via NFS.  Using a dual head card w/ two 
LCD panels attached.   Install gets through the Anaconda probes for the 
video card (ATI Fire GL X1), monitor (LCD NEC 1860 ) and USB mouse  and 
then hangs when  the Graphical Installer starts X  (killing the sync to 
the monitor).  A retry with a 'linux text' install works just fine.  
Same thing then happens subsequently with a running system when starting 
X and using the stock config file.  SSH into the box shows the kernel 
still spinning and X, gdm-binary, greeter still running.  The XFree log 
shows no problems  (EEs).   Fix:  I had the 2nd NEC 1860 attached to the 
Fire GL during all this and the X log shows probing for it  though 
obviously there was no dual head configuration in the XF86Config file at 
the install point.  I unplugged the 2nd monitor from the Card and all is 
well;  X starts w/ out any trouble.
