Okay I'm guessing here from memory but i think it was from a terminal..

sudo init 1

This drops you into a prompt in recovery mode then run..

dpkg-reconfigure xserver-xorg

and then..

 init 2

 back into the desktop.

The reason or so i was told was that sometimes  hardware cannot be auto detected
 from within a running x session.

 After a brief search another way would be to hit escape on boot and then in grub chose the recovery console and run
dpkg-reconfigure xserver-xorg  from there.
