edit the xorg.conf file adding the resolutions your system supports.

sudo gedit /etc/X11/xorg.conf
Look for "Modes"

Mine looks like this:

Modes      "1280x1024" "1280x960" "1152x864" "1024x768" "832x624"
"800x600" "720x400" "640x480"

I had to add all but "1280x1024", which was added during the install.

If this doesn't work right off, you will likely have to create some
"Modelines" which is more complicated. Google is your friend here, since
someone likely has already done this on a system similar to yours.

You may also want to change your DefaultDepth to 24 if it isn't already.
