Matrox G400 dual head mode not working... (but it used to in 11.1)

Hi I had been unable to set a matrox g400 into dual head/xinerama mode in
opensuse 11.2 (32 bit).
Copying the old xorg.conf that used to work until the update ends up being
kicked to console mode. (i will have to check if there is a log file with
errors).

I also tried sax2, set the 2 monitors, xinerama, but this does not work
either. When going into the test mode, one of the monitors has a virtual
screen larger than the physical screen, but no video sent to the other
monitor.

Would anybody who made this work, please kindly post their xorg.conf?

Many thanks

Apparently this is a bug in the current mga driver… but on top, even if
the driver worked OK, kde does not yet support multiple monitors in xinerama
the way that the mga driver controls them (is this as multiple X devices?,
unlike most multiple screen setups). I was told that kde4.4 would, though.
So I have to double hope now!! :slight_smile:

I also own a Matrox G400 DH, but only have 1 monitor hocked to it (so single display).

I suggest to upgrade to openSUSE 11.3, then install the latest Mesa package from the Factory repository (hardware acceleration is back !)
I did a fresh new install for 11.3. The way X is working is different, xorg.conf is no more used (well until you have or add one), almost everything is automatically detected and configured. I currently have no problem with the mga driver.
