It would actually be 2 this is what I need them to do:

Change xorg.conf
Log out of ubuntu
Log back into xbmc

and then one to do the opposite. This is so I dont have to go through half a dozen steps to change the display setup. It would be great if I could have a .desktop file that would dock into unity.

Ive attached the 2 versions of xorg.conf that would have to be swapped.
