Matrox G550, TNT Riva, Multi-head X THREE monitors
 
This was a raging beast to set up, and I'm still twinking around the config some, but I finally got a tri-head working with the G550 Dual Head Matrox card and an old Nvidia driver TNT RIVA. XFree86 4.3.0, and the Matrox 2.1 driver set (for X 4.2.1, just copied them in :) )

For academic value, and maybe so someone doesn't get a headache for 3 days like I did, here's the whole of the XF86Config file... the last one anyway, of about 12.

Code:

That's a bit of a beast. I had to merge the Matrox displays otherwise I kept getting annoying artifacting and an unusable display out of the 2nd head on the Matrox card.

Cheers,
