Hello Matt,
Thanks for the compliment :)
- For a CRT monitor, it doesn't require X to be restarted. We can plug-unplug 
anytime, the display will be there.
- But for LCD projector, it does require to be plugged in before we login in 
Gnome. I believe it depends on the projector type. Also one annoying note, if 
I left the notebook long enough until the screensaver start and then the 
screen goes to sleep, the projector cannot be waken up until I logoff and 
logon into Gnome again (no need to restart X though).
- A little comparison to Suse's setting. The projector can always be waken up. 
But, sometimes Suse sets the resolution wrong (lower). Too bad I didn't save 
the Suse xorg.conf before I format my notebook. Also the projector has to 
be "On" and plugged in before we start the notebook (in Suse we can see that 
it tries to detect the hardware because both screens will be blinking longer 
than usual).
