I am trying to get an external lcd projector working on a Dell D531 with ubuntu gutsy (32bit). I noted on several forums to try:

aticonfig --enable-monitor=lvds,crt

But I get:
Using /etc/X11/xorg.conf
Saved back-up to /etc/X11/xorg.conf.fglrx-1

Actually, I don't see this documented when I just go aticonfig. What is the correct way to enable an lcd projector on a laptop?
