I'm driving a pair of 18" 1280x1024 lcd's (NEC Multisync LCD 1850x)
via their DVI connectors w/ a Matrox MGA-G550 AGP card w/ the funky
single high-density connector.

Dual-headed DVI functionality requires you to use the binary mga_hal
blob, and the port doesn't work with the Xorg 6.9.

I had to fart around a bit to make it work, but did eventually put
together a recipe, which is posted at

I've also hooked up the same monitors to a Matrox P-650 but didn't
explore it very much.  It might be interesting because it has a higher
maximum pixel count.

I spent a couple of hours wrestling w/ an nvidia based card on Fedora
core 4 last weekend and eventually got Xinerama working with the
binary nvidia driver, but never made it work w/ nv driver.
