You should make sure that you give it the maximum screen resolution you
want to use in the form of a "virtual" statement in the xorg.conf config
file, e.g.

Section "Screen"
        Identifier      "Internal Screen"
        Device          "Intel 965"
        Monitor         "IBM ThinkPad LCD"
        DefaultDepth    24
        SubSection "Display"
                Depth           24
                Modes           "1024x768" "1280x1024"
                Virtual         1280 1024

This works for me, but maybe it is also superfluous with the newer
servers which do more and more auto-configuration.

Hope this helps
