[Wylug-help] Different Content to Different Displays Under X

[Don Magee]

I have had dual screen set up with two graphics cards using xinerama. 
You could drag windows from one screen to the other.

The configuration was done in xf86config. But it was some time ago and I 
can't remember the details. From a quick google, xinerama still seems to 
be around.
