Hi Christopher, I'll check if I'm able to update, it's a business notebook where I have limited access. I have to check what's possible there.
What I tried is the latest stable mainline kernel 4.6.3 which improves the situation significantly. At least the NB doesn't crash any more putting it back to the docking station. The mainline kernel doesn't support Docker (AUFS missing) which makes it problematic for me. I keep you posted Haug Am 03.07.2016 um 00:59 schrieb Christopher M.

I experience black screens for about a second. Usually one of the external monitors only. One external display turns black and comes back after 1 or 2 seconds. This happens >10 times a day and is really annoying. My colleague experiencing the same issue, also using Ubuntu 16.04. Same hardware. At home I have a similar issue, also with Intel motherboard graphics. Different hardware.
