Hi Dariusz, I think I have this part: Manufacturer Part# : XX6F0 | Dell Part# : 331-6307 I am not sure if that is a DP hub, it is beyond my knowledge. I used your kernel and the xserver-xorg-video intel driver from URI was: http://ppa.launchpad.net/pool/main/x/xserver-xorg-video-intel/xserver-xorg-video-intel_2.99.916+git20141016.6b98f162-0ubuntu0sarvatt~trusty_amd64.changelog How does the xorg-edgers repo provide a driver? I don't see it, while the repo is enabled. When I had a fully working situation the last time, I did not see any xserver-xorg-video-intel driver installed. Is it another driver or package you are referring to?
