Maybe this helps:

Hi Andreas,

tried and got 2 separated X windows session (so, was not able to move windows across - which I already had once. See attached conf and log files).

Right now, I have no xorg.conf - but still 2 monitors are treated as 1 screen - so full screen is displayed in the middle...

Thanks anyway.

With best regards.

Regarding script:

$ locate display-setup-script

$ pkg search -r display-setup-script [nothing]

Where to find it?

I meant /etc/lightdm/lightdm.conf setting 'display-setup-script'.


So,

you are able to play full screen video on one monitor only?

Which graphic card you use (I mean, if nvidia, did you used
nvidia-settings)?

Yes, if second monitor (TV) is unavailable, Mate uses just primary
monitor. In both cases I can play full-screen video with vlc. I
haven't used nvidia-settings tool, can look share xorg.conf or
Xorg.0.log in the evening.


I've found out that my desktop doesn't have xorg.conf and I see the
following in Xorg.0.log (see attachment).

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.
