2 graphics cards (nvidia, intel), 3 monitors, and some questions

I'm trying to coax Xorg to ru three monitors, two plugged into an nvidia 970 with proprietary drivers, and one into an i5-3550 igpu. All dvi conenctions. Multigpu is enabeld in bios. Right now only the intel monitor is displaying. The only xorg config I am using points the devices to the proper bus. I did as much homework as I could, but all the documentation I can find discusses all the monitors plugged into one card or the other, not both.

Here is the pastebin to my log /

Can a single x session work or will I need to run separate sessions for each device?
Is bumblebee viable with this setup? It is currently running successfully.

Re: 2 graphics cards (nvidia, intel), 3 monitors, and some questions

I have a similar setup at home with an ATI 7850 + i7 CPU hooked up to three monitors, and I can state from experience that it is a massive pain to get working.

Bumblebee was not necessary, but I had to go with a classic Xinerama setup w/ xrandr disabled via a manual Xorg config. I'm not at home at the moment, so I don't have access to the X config, but it included two device definitions (ATI + Intel), three screens, three monitors, and one layout. Look around for the X config syntax online.

In case you've already done this, paste your X config and I can have a look.

Well, now I have the two nvidia monitors running, while tty is on the intel monitor.
