The screen will flicker when it's using the wrong the refresh rate. Use
a modeline generator and see if you can force it to use the correct
These might help:
I've also got this in my notes -
"To get desired /etc/X11/xorg.conf one can modify the /usr/bin/dexconf.
This script generates xorg.conf automatically in liveCD session
according to the booted machine."
Hope you get it fixed.
