I'm trying to get an external monitor to work with my Dell e7440 laptop via mini displayport.
All that happens is that the laptop display flickers a bit and I get this in dmesg:
The external monitor in questing is an iMac 27" in target display mode (it's the 2009 model that supports mini displayport).
Unfortunately I don't have any other mini displayport equipped machines that I can test with, and I don't have Windows on this machine to check if it is a Linux specific issue, so it's a little bit hard to troubleshoot.
Does anyone here have any experience with this combination of hardware?
