Thats what I now have. A 6 monitor machine, with 3 Matrox G450 cards, 1 which is AGP. It was so nice to see digital photographs fill a wall like that :-) Pixmap operations work on all of them. The monitors are all 19". Most of them are monosync, so I had a hell of a time adjusting modelines. I get the impression it is quite unusual with such a large xinerama. Text also seem to work mostly, but not the background of text. Anyway, I have some problems, which seem to be due to the driver, which is the "mga" driver from XFree86. I use KDE, under SuSE 7.3, but installed XFree 4.2.0 from scratch over this. As mentioned, pixmap operations work fine on all screens. However, there are some pointerproblems, where the pointer leaves trails of small white squares, on 2 screens, when moved too fast. Menus, windowborders, and X11perf all look horrible, cut to shreads, chaotically striped. So, there is obviously something wrong somewhere, and thats why I write to you good people. First card, G450 AGP Both screens work perfectly. Second card, G450 PCI Stuff get shredded, as described above, on both screens. Third card, G450 PCI Same as above, but pointer also leaves trails, on both screens. I have tried changing bits per pixel, with no effect on the bugs at all. I enclose my XF86Config file below.
