[SOLVED] Xinerama = all black screens on login

Calebjonmarcus · 03-03-2019, 09:19 PM

So I am running on Bodhi 4.5, I have run into a odd issue. I have 6 identical monitors set up on a GTX 750 ti and a GTX 1050 while I can have both screens up on 2 xscreens. Works great other than when I enable Xinerama and restart lightdm everything comes up on black screens.

Does anyone have any ideas?

My xorg.conf

Code:

After lots of digging and googling after I found the Nvidia logs. They need to be the same GPU and it cant be two different ones. I have ordered another one and will report back with my findings.
