I have a linux system (CentOS 6.5) with a Quadro K2200 and a GeForce GTX Titan Z in it.
I’m trying to have a separate x-screen on each GPU.
Xscreen0 is setup on GPU0 (the Quadro), but xscreen 1 & 2 are both on GPU1 with no xscreens on GPU2. I don’t see any way to make xscreen 2 be supported on GPU2 (the 2nd GPU on the Titan). I’ve tried plugging a monitor for screen 2 into a dvi connector and the displayport on the Titan card itself that didn’t change anything.
Here’s my output of nvidia-xconfig --tree:
Using x configuration file: “/etc/X11/xorg.conf”.

Can’t each GPU on a dual GPU card have its output go to a xscreen?
Basically, I’ll want to just run my dual monitors for the desktop (xscreen 0) with the Quadro and
do some separate rendering on each GPU of the Titan Z. I want the images that each GPU of the Titan Z makes go to a
separate monitor.
Please help! Thanks a lot.
