SUMMARY
When I close my laptop lid and open it later on (but this only appears if I am
not connected to my Lenovo docking station any more). Plasma and everything
else crashes, I need to relogin. Sometimes I even need to reboot because the
session has many errors after a relogin.
STEPS TO REPRODUCE
1. Work normally (docked)
2. Go into standby (suspend to ram)
3. Undock the notebook (in this case a Lenovo W540)
4. Open the laptop lid again
OBSERVED RESULT
