Subject: Re: multiple monitor config Red Hat 9

I used to have a dual monitor setup with RedHat 7.3. An AGP GeForce 3 with a 19" and a PCI S# Virge attached to a 15". I no longer use the 2nd monitor, but I still have the stuff in my XF86Config-4, just commented out.
I pasted the relevant sections below. The key parts are you just set up each monitor, card, and screen, and then in ServerLayout, you just have two (or more) 'Screen' lines. In my case, the line "Screen 1 "Screen1" Above "Screen0"" tells X to arrange the desktop so the 15" is above the 19".
The "Option "Xinerama"" will make the screens join together in one big screen, otherwise if you leave it out, the two screens are treated separate desktops. IIRC, in that case, your mouse can go back and forth between the screens, but windows cannot. Also, with it off, your screens can have different resolutions/color depths. If you have Xinerama on, they must have the same resolution and colordepths (I believe this may have changed in more recent releases though). If one screen has a smaller resolution, like mine were set up, the smaller screen will pan around. I forget what that's called - Virtual Desktop?
Anyway, hope this helps.
Justin
