Muliple Xorg Displays (Triple Head)

Most people will run a single video card with one monitor. What if you wanted to run three video cards to three monitors, but you did not want to run Xenorama?
We wanted a work station where each of the displays acted like a seperate desktop, but we also wanted to move the mouse between all three displays. This allows us to have many virtual desktops on each monitor. In essence, we can switch virtual desktops on one monitor and it will _not_ affect the others.
The following config will allow Xorg to setup three X servers. Put it in your /etc/X11/xorg.conf after you configure it for your hardware.
