Backup the xorg.conf file. From a terminal:

sudo dpkg-reconfigure -phigh xserver-xorg

That will try to fix the X server (it's the same thing that selecting
option #4 in the recovery boot does) and set a generic xorg.conf. Note:
you can view the script for the xfix option here:

cat /usr/share/recovery-mode/options/xfix

Or, if you know what type of graphic card & monitor, you can try with a GUI:

gksu displayconfig-gtk
