Description Simone Gaiarin 2016-11-30 11:54:26 UTC
Since few days (probably from when I updated to Plasma 5.8.4) when I undock/dock the notebook the screen configuration is not changed at all. kscreen.log is not filled. It seems that KScreen is doing nothing. 

Example:
Undock notebook:
- In KCM I can still see 3 screens
- Panel not moved
- Mouse can exit the notebook screen

Redock notebook
- External screens not activated

I need to reboot every time I dock/undock. Sometimes docking causes the crash of X, showing the login window afterwards.


How can I debug this and provide more information? The kscreen.log is not populated after I undock, so I don't think is so useful.

Apparently was a problem with the specific kernel. Works with kernel: 4.8.14
