RE: Triple headed Linux beast of doom (Score 2, Informative)

I also have a triple headed machine at home with a Geforce2 and older matrox cards. I agree with your advice about keeping the cards separate.

If you want a 3 head machine for cheap, I'd reccommend getting Matrox Millenium II PCI cards ($20 on ebay). You can stick up to 4 of them in one machine. I have an AGP Geforce2 as my center display, and use that for games. The Mellenium IIs are plenty enough for stuff like xterms and web browser windows, and the geforce card runs games well. It was all surprisingly easy to get working.

I dual boot linux and XP, both OSses support the display set up fine. XP acts kind of bizarre when you start a game on the center display and it changes resolutions though.

If anyone wants my XF86Config file I'd be happy to post it.

To confirm your belief about running separate X servers on each display: yes that is possible, I've done it before. Its a good way to get everything debugged as you're getting it all configured. The problem with separate X servers is that they would be conflicting for your input devices. A better way would be to use 1 X server, but configure it for multiple displays. Each display will be separate and will have its own minor display number (:0.0, :0.1, :0.2) and can be at separate resolutions/refresh rates. The mouse can be moved across displays and keyboard input will follow mouse focus. However with separate displays, you can't do things like drag windows across monitors. Its better to use Xinerama, which makes them all into one big display. Enlightenment works well with multi heads.
