[Cooker] ATI and a Samsung SyncMaster

[Phil Green]

I have just installed 8.0 on my new machine that has a ATI DDR Radeon card 
and a Samsung SyncMaster 770 TFT monitor.  When I try to do a startx or 
configure the X Server, my machine locks up and I have to power off.  There 
isn't anything in /var/log/syslog that tells me what the problem 
was/is.  Does anyone have any ideas on this??
