I've struggled with this issue for the past 8 hours, finally resolved it, and
wanted to share.

I just upgraded to Suse 11.1 from 11.0 on a Dell Vostro 200 with a Intel G33
video card. 11.0 has always worked great for me with no problems.

After a clean install, booting into Suse 11.1 generated a blank screen after
user login and shutdown my monitor, but the box was still running. I needed to
power-down and power-up the box to get back in.

On KDE(3.5), I was only able to run 11.1 in Failsafe mode. I could run 11.1 on
ICEWm or TWM, but not my choice of session types.

I was finally able to resolve the problem by changing my driver designation in
my xorg.conf file from 'intel' to 'vesa' as below:


Section "Device"
BoardName "G33"
BusID "0:2:0"
Driver "vesa" <---CHANGED
Identifier "Device[0]"
Screen 0
VendorName "Intel"
EndSection

I can't take credit for this as the solution was offered on a forum(possibly
this one, but I've only visited a dozen forums in the last 8 hours and can't
remember which one had the suggestion).

Hope this helps.
