[Grüninger, Andreas (LGL Extern)]

Maybe this helps:
nvidia-xconfig --enable-all-gpus --separate-x-screens

Hi AlP, all...

I just wanna share my frustration (as well as xorg.conf and Xorg.log.0 files). I have also tried configuration w/o xorg.conf - nothing has worked as expected.

I just gave up. So, to summarize:

a) under gnome (before mate) I was able to use xinerama and to have 2 different x screens on NVIDIA Corporation G92 [GeForce 9800 GT] card
b) changed to MATE and 2 screens suddenly were "glued" into single space, so I have tried following (in order to get separate screens working):
   1) removed /etc/X11/xorg.conf - no luck
   2) called nvidia-settings (and tried also nvidia-xconfig) which have created xorg.conf file, but no luck in splitting screens (and being able to move applications between them - two completely separated/isolated x session is possible - that is not goal)
   3) performed modifications as it was suggested by Ken Mays (in separate e-mail thread) and as it is suggested in http://http.download.nvidia.com/solaris/340.102/README/configtwinview.html
and http://www.firstalt.co.uk/help/nvidia.html - but still there is no change (I always get "(WW) NVIDIA(0): Option "TwinView" is not used")
   4) looks like System -> Preferences -> Hardware -> Monitors detects both monitors properly, their position, resolution, etc... but it is not of use in this case.

So, I have been stuck with one huge desktop, combining two monitors of different resolution and full screen playing on both (centered between
them) - very ugly for watching.

Many thanks for help. There is nothing to document unfortunately.

With best regards.
