Hi Michael,

it depends on how you would like to use the external card. Please
specify your scenario. 
Anyway, try to look in /etc/gdm, /etc/init.d/xdm, /etc/X11 (there can
be specified which server start in file xdm/Xservers)

I have DL adapter connected to my docking station and a simple script
to activate the second xserver on docking and deactivate that when
undocking. I simply run here second desktop using x2x. I just use that
primary for web browser, so I dont need xinerama.

You can also use DL with your primary card and xinerama. But it needs
specific xorg.conf and needs to be connected when xserver starting. So
nothing suitable for notebook and hotplug.

Robert.
