Hi, I have a problem with configuration two graphics cards, 4 monitors. I can run X.org on first or 2nd graphics card, but when I try run both graphics cards, all monitors are on, but X.org run only on one graphics. Interestingly that when I press ctrl+alt+f2, new terminal open in monitors 2nd graphics.
Xrandr sees only one graphics outs.

Are you intentionally using nouveau rather than the nvidia blob?
Please paste the xorg log.
