In the mean time, there is a file in /etc/X11 called xorg.conf which contains the screen configuration. There is probably also one or more backup files which contain previous configurations. You can try something like this:

cd /etc/X11
sudo cp xorg.conf xorg.conf.BAD
sudo cp name-of-backup-file xorg.conf

Then switch back to X using ALT+F7 or similar and pressing CTRL+ALT+Backspace to reload X.

Have you tried turning it off and on again?
