Kim, I am seeing similar problems on a redhat system, but mine are much worse. As far as I can tell, the G450 cards work okay as the primary video controller, but present garbage on the screen when used as a secondary controller.
All my cards are PCI. The 2 heads connected to the primary controller work fine, but the other heads look like they are displaying random memory. Any pixmaps that get written to the displays look great, but the pixmaps are surrounded by garbage. I am note an expert on XFree86, but my XFree86 log file looks like the i/o memory on the secondary cards is marked as "Inactive PCI" while on the primary card, the i/o memory is marked as "Active PCI". BTW: my XFree86 configuration file is very similar to yours. Gregg --------------------- 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.
