This looks like an issue with the dock station hotplugging a PCI device and it not being detected by X properly. IIRC, one of the on-dock DP ports on the ThinkPad docks is the same as the mini DP port on the laptop; that output should always work. So if you only need a single output, that's a potential work-around. Beyond that, I think this might be a missing feature in the version of the xserver-xorg-video-intel driver that you have in Debian vs whatever version you had installed in Ubuntu. I'd compare the two versions, and possibly upgrade your jessie install of xserver-xorg-video-intel to the one in backports, which is 2:2.99.917-2~bpo8+1, and significantly newer than 2:2.21.15-2+b2. -- Don Armstrong http://www.donarmstrong.com Nothing is as inevitable as a mistake whose time has come. -- Tussman's Law
