The Display Port on my T420 is attached to the nvidia card, so there is no chance to access it via the intel card.

However I can output data on it tweaking bumblebee's xorg.conf changing the "ConnectedMonitor"-Option:

Driver "nvidia"
VendorName "NVIDIA Corporation"
Option "NoLogo" "true"
- Option "UseEDID" "false"
- Option "ConnectedMonitor" "DFP"
+ Option "ConnectedMonitor" "DP1"
EndSection

Additionally with a real Monitor "UseEDID" should be true of course.

The feature request is use something like optirun --monitor dp1 to automate that.
