Triple / quadruple head config

[Michael Schmitt]

Hi list,

Triple / quadruple head config with one nvidia 980XGL (sorry) and one
matrox G450... anyone? :) I know nvidia is closed, but as nouveau is not
ready yet, I need to stick with nvidia, for now :) I want to be able to
use OpenGL apps on the displays connected to the nvidia card, I want to
have _ONE_ big screen spanning all displays, but if I maximize an app,
it should just maximize to the borders of ONE screen... it is a mixture
between twinview and xinerama (I think). My config trials up to now
were... hum... more or less strange. The best I could get was this:

The two displays connected to the nvidia are "together", applications
are maximized across both displays, the one (later there will be a
second one) connected to the matrox has its own panel (I use gnome), I
can move the mouse between those three displays but I can not drag apps
from one nvidia display to a matrox display.
So anyone thoughts on this? The xorg.conf is attached. It is more or
less a rough config, no language settings or other stuff, just the
display / graphics stuff is of concern now.

As a side note, edid / ddc seems to be broken with the matrox or the
display connected to it, not that important either, I will check that
when all works as I want it to.

regards
Michael Schmitt
