Is the second card clearly in graphics mode and simply misdisplaying due to being out of timing sync? When I ran multiple Matrox cards, XFree86 4.x mistakenly decided to only use EDID timings from the first monitor and supported modes from the first card to select timing modes across the whole set. In my case, I was using a G550 and a G450; the 550 could drive the monitor at *5Hz, the 450 only at 60Hz, but XFree was insisting on selecting an 85 Hz mode for driving the 450, even though it had correctly sensed the card did not support it. > Is there anyone out there that has managed to get two Matrox cards to work > using Xinerama? Yes, I drove three different cards (550, 450, 450) in one system, as well as mixing Matrox cards with cards from other manufacturers with Xinerama. Aside from the timing issue (and the hardware cursor being broken), it all just worked.
