There's two ways that this works:
Traditional Multidisplay - You have display 0 and display 1, you cannot
drag windows between them and you have to use DISPLAY or a parameter to
most programs to run it on the second display. Not many window managers
have *great* support for this.
Xinerama - a single display expands across the two monitors. This is new
in XFree86 4. It's somewhat inefficient and memory hoggy, but it's very
usable and cool anyway. Most of the more modern window managers support
I'll pop up my XFree86 config if anyone's interested. I would be interested
to see if I can improve it in any way too. Worthwhile?
