Application: plasmashell (5.6.1) Qt Version: 5.6.0 Frameworks Version: 5.20.0 Operating System: Linux 4.4.6-1-MANJARO x86_64 Distribution: "Manjaro Linux" => and 2 screen : one is the computer, the other my TV witch doesn't have the same resolution (less). -- Information about the crash: I was plugin the HDMI cable to have my desktop on my TV. Turn off, turn on, turn off turn on my tv and it crach. More generaly, I notice that the only way to have a desktop working on tv is to do this in the order : 1) let linux turn on 2) if I plug an HDMI cable the TV must be Off 3) when I am completly log in my computer, now put on the TV If you don't do that the desktop is in mess ot it crash (but less those 2 last month : a correction?) The crash can be reproduced every time. -- Backtrace: Application: Plasma (plasmashell), signal: Segmentation fault Using host libthread_db library "/usr/lib/libthread_db.so.1".

I have a laptop with a docking station and a monitor attached to it over DisplayPort. Quite often when I leave the desk and the screen automatically blanks the monitor will switch itself off and unplug itself from the system (supposedly a standard DisplayPort behaviour). Once I come back and wake everything up I see Plasma restart itself and this crash report pops up.
