Hi all,

I have been trying to configure my three monitors with cinnamon, the problem is that when I maximize a window it maximize over all three monitors.
What I want is to maximize a window in each monitor.
I'm running an NVIDIA card:

Code:

 03:00.0 VGA compatible controller: NVIDIA Corporation GM107GL [Quadro K2200] (rev a2)


I tried by using xinerama but when I enable it, Cinnamon keeps crashing all the time. I have tried several configurations in the xorg file with no success.
Tried also compiz, but is very incompatible with cinnamon, the windows manager works fine but the desktop enviroment is not fully functional.

Does anybody know what can I do?


Regards.

It depends on

a) gpu driver => binary vs open source one
b) xorg configuration => see step a)
c) desctop environment

all these have some sort of interaction and prioritization on how they work

xrandr is an official configuration utility to the RandR X Window System extension. It can be used to set the size, orientation or reflection of the outputs for a screen. For configuring multiple monitors see the Multihead page.

depending on your desctop environment you may be able to write rules for some applications or create some shortcuts for such things. i3wm can do such things for example.

Basically only two choices:
- Xinerama
- 3 screens handle by the same card

You should not use xinerama (the xorg module) that the drivers themselves emulate/handle with TwinView, but use the xinerama useflag that will enable your Window manager to use Xinerama feature. got it? (xinerama in xorg off, xinerama useflag on).
