I use a single /etc/X11/xorg.conf with a modifed Screen Section[1](add
a Virtual line).

then use 'xrandr --output VGA --auto --output LVDS --auto --right-of
VGA' to turn on dual head support.

[1]
Section "Screen"
        Identifier      "Default Screen"
        Device          "Intel Corporation Mobile GM965/GL960
Integrated Graphics Controller"
        Monitor         "Generic Monitor"
        DefaultDepth    24
        SubSection "Display"
                Virtual 2560 1024
                Modes           "1280x800"
        EndSubSection
EndSection
