--- Comment #5 from prettyvanilla@posteo.at --- I am running a current mainline kernel until dpm stabilises, so I am on 3.11rc6 currently, which has the patch mentioned already applied. Sadly, no change in behaviour. I updated the dmesg output attachment and added xrandr and X.org log output. Anything in particular I should look for to get to the root of the problem?
