GPU per monitor

Hey;

I’ve got two GPU’s and 2 monitors and wondered if it was possible to use one for each monitor? I’ve been playing around with /etc/X11/xorg.conf and can’t get my secondary gpu to display.

I read somewhere it might be due to the proprietary nvidia drivers…& Their own implementation of Xinerama. Does anyone know if that is the case…?

Second GPU is AMD, open source radeon driver.

xorg.conf…

I did notice RedHat also appears to have a nice GUI for this? I’m on Arch
Any help appreciated
