duel monitoirs wiyh two graphics cards

[JCFreak]

Hi can anyone help me. I'm wanting two set up to screens with using two graphics cards. I want to set them up like how you r able to set duel sreens in windows one sreen being a part of the desktop of the first sreen.
the linux I'm using is fedora core 3. and I'm new to it so I need to know how to do it step by step.

please understand that I'm only thinking aloud here.

You should be able to edit (as root/ su -) your /etc/X11/xorg.conf file (make a backup copy of it first). You'll find a chunk of code called the device section. You'll want to end up with two of these, one for each card. Then you'll need to end up with two monitor and two screen sections, to go along with the device section (one for each).

Then you should (note that word) have a working def for two monitors on two cards (you'll need to have restarted X (Ctrl Alt Backspace kills it, it should then autorestart at the login prompt.).

I decided to give you a little more help since I'm cool like that. Here's the /etc/X11/xorg.conf file i use for dual display. To use separate cards you will need to define them (including drivers) as necessary in the following file...

xorg.conf

Section "ServerLayout"
        Identifier     "Multihead layout"
        Screen      0  "Screen0" 0 0

        EndSubSection

EndSection

        SubSection "Display"
                Viewport 0 0
                Depth 24
                Modes "1024x768"
        EndSubSection
EndSection 

Section "DRI"
        Group  0

EndSection

Don't forget to backup your xorg.conf before editing it incase anything goes haywire.

# cp /etc/X11/xorg.conf  /etc/X11/xorg.conf.bak

You may need to adjust the HorizSync & VertRefresh according to your monitors otherwise the resolution will be off
