Boot into single user mode (at the grub prompt, add "single" to the boot
parameters).  When you get a prompt, go to /etc/X11 and, if xorg.conf
exists, move it to xorg.conf-.  Then exit.  The X server should default
to a proper configuration.  You can then check the xorg.conf- file to
see what got mucked up.

If there is no xorg.conf file, I don't know what Ubuntu changed to set
up the dual head (multiple monitors).  If you have an nvidia chip then
there *might* be some other config file out there, though nvidia also
uses the xorg.conf file.  All other chips are supported with the
xorg.conf file.
