These instructions are for the open source ati driver, because fglrx still sucks (Dec 2007).
Nuke all the deprecated cruft from the xorg.conf file. So that's the HorizSync and VertRefresh from Monitor sections, and any manual Xinerama or dual head configs.
Add a Virtual line to the Display section:
Section "Screen"
Identifier "Default Screen"
Device "ATI 200M"
Monitor "Laptop Display"
DefaultDepth 24
SubSection "Display"
Modes "1280x768"
Virtual 1280 1536
EndSubSection
EndSection
Then use xrandr to wake up the other end of the DBUS cable:
xrandr --output VGA-0 --set load_detection 1
Clone the desktop:
xrandr --output VGA-0 --auto --mode 1280x768
Or extend the desktop:
xrandr --output VGA-0 --auto --mode 1280x768 --above LVDS
