here's an xorg.conf file for 4 joined screens - 3 across and one above the
center screen. The stacked screens are very wide screen Dells. The two side
screen are rotated to match height. This is using an Nvidia (duh!) Quadro
NVS 420 (4 output screen using funky splitters).
cat /etc/X11/xorg.conf

*Every time you stop a school, you will have to build a jail. What you gain
at one end you lose at the other. It's like feeding a dog on his own tail.
It won't fatten the dog.
