FGLRX dualhead

28 May 2006 I brought up my old 19 inch screen from the basement and hooked it up to my laptop. I remember how I had my svideo working in Windows on my old laptop and I wanted to see how easy it was in Linux.

As it happens, it is extremely easy.
Debian has a package called fglrx-control which is a nice GUI-tool to set dualhead and whatnot.
Of course, you need the fglrx driver loaded for that.

This post on the Gentoo forums can be of some help.
Debian doesn't give us an fglrxconfig tool, but has renamed it to aticonfig.
running it like this:

aticonfig --initial=dual-head

will get you a basic dualhead config. restarting X then lets the magic happen! :)
