Yes, indeed, commenting out that line starts the display on an external monitor.
With a bit of experimenting I now have instead
Option "TwinView" "true"
Option "TwinViewOrientation" "clone"
in my xorg.conf. Now I can switch between the external monitor and my
LCD by pressing the "Fn-CRT/LCD" key. However, I need to issue the
command "xrandr -s 1024x768", since the external monitor doesn't
support my default of 1400x1050. Does anyone know how to make the
virtual screen size default to one supported by both monitors?
Also, when connecting the external monitor I need to restart X. Would
be nicer if that weren't necessary. Ideas?
