I've not worked this out on a dual video-card system, but:

1) I believe you can't use both the Intel card and the nVidia card at the same time in these types of installations. You can use "bumblebee" to switch back and forth if you need that functionality.
2) If xrandr reports one only monitor, nothing you can do will turn the second one on.

I'm surprised to see xrandr reporting six Display ports. I might help if you provide more info: connection types, monitor types, Dell model, etc.

I was using a Dell docking station with a VGA and DVI monitor. I tried going back and forth between proprietary and open-source drivers to see what was the issue. This caused my system to be hosed. So I reinstalled Kubuntu, kept the open-source drivers and got rid of the DVI and docking station. Everything is awesome! I have the VGA as my primary and laptop as secondary. I got rid of the docking station b/c it causing wierd issues. USB ports were not responding well and overall system slowness. When I go rid of it everything was back to normal!. The only thing is I see that Kubuntu is not using the nouveau but the intell driver for rendering. Any way I can change this? See below

Code:

You'll need to figure out bumblebee. I haven't had to mess with it so I can't help. It only works with the nvidia driver I think, but once installed, you can select nvidia or intel video.

Seems to me the problem was that docking station. Weird because I've used Dells with docks for years and never had a bad dock.
