i agree with Tom,
backup your conf file then do the dpkg-reconfigure xserver-xorg
that will get you rolling....which version of ubuntu are you using? I
noticed in 8.04 some things changed with reconfiguring...it seems like it
defaults to the 'simple' rather than letting you select it from a choice of
3....you can always just manually add in the resolutions you want...then
just CTRL+ALT+BKSPACE to kill the desktop and reload it...
