Hello I have an issue configuring base mosaic on my system.
The final configuration I’m targeting is to run 6 screens on two GTX 970 (same environment)
The thing is that there are in a production environment and I don’t want to brick the installation with hazardous commands for now :-).
FYI I get the exact same output on both computer.
For now I’m just trying to get my two GTX550 to work.
Here is my xorg :

As described on your website I already tried to disable NvidiaXineramaInfo and Compositing
Any way to get more information and solve this issue ?
