screen photo showing corruption

Initial post was at: http://forum.tuxx-home.at/viewtopic.php?f=1&t=595

Centos 5.1 (both 32 and 64 bit versions)
X Window System Version 7.1.1
xorg-x11-drv-mga-1.4.2-6.el5

It seems the memory is nor properly separated across the cards. I wonder if it is something simple that I can change on the config files.

I've attached the config, log and a couple of photos of the screens to clarify what happens to the video data. The vertical mismatch is due to the physical height differences between monitors. The important thing is that the primary monitor (connected to the 1st mga device seems to render things properly, but the rest don't). As time progresses even the main screen starts to miss blocks of pixels.

Does anybody have the G200 MMS in a working 3 or 4 monitor setup with xinerama? Any chance you could share the config files and info on what distro? I really don't mind using any modern supported distro as far as I can get this to work.

Thanks,

Alberto
