Try this:

xrandr -s  800x600

Adjust resolution itself as necessary. This works if you've got a running X11.

If the GUI won't start at all, you may want to try removing xorg.conf; as far as I remember it should be automatically regenerated. But just in case, let's just move it aside instead of deleting it.

sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.backup

the second command has to be executed as root, I suggest adding sudo in front of it.. – 0x89 Sep 7 '09 at 13:38
