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 Crash EXPECTED RESULT No Crash SOFTWARE/OS VERSIONS Linux/KDE Plasma: Kubuntu 20.04 64bit; Linux 5.5.2 (available in About System) KDE Plasma Version: 5.18.0 KDE Frameworks Version: 5.67.0 Qt Version: 5.12.5 ADDITIONAL INFORMATION Using staging kde frameworks, mesa drivers.

Sorry for the delayed response. We will need a backtrace of the crash to proceed, if the issue is still reproducible. Please see https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports Thanks!
*late response*. After a fresh install (and probably some updates, I can't reproduce it anymore) (It's probably not fixed, but there is no option for "Can reproduce anymore", so I'll mark it as fixed)
