marked this fix-released. I dont see the problem any more. It is possible it still affects 4.4 series, but bionic is fine for sure.

The system initially logged in and my screen layout was lost (instead ie, the monitor on the left was on the right). I changed that back, logged out and back in. Now, occasionally and seemingly randomly the larger display goes black for 1-2 seconds during usage. It often occurs when switching desktops via hotkeys, but sometimes at other random points. After playing a bit, I'm pretty sure the reason is that I'm getting the vesa driver instead of the intel one.
