This means that Ubuntu is running the VESA graphics driver instead of
the driver specific to your particular hardware.  If you have the file,
simply restoring /etc/X11/xorg.conf should solve the problem.  Otherwise
you can configure you X server settings by using
"System->Administration->Screens and Graphics"
