Bug ID: 360641 Summary: Plasma randomly crashes after inactivity Product: plasmashell Version: 5.5.4 Platform: Ubuntu Packages OS: Linux Status: UNCONFIRMED Keywords: drkonqi Severity: crash Priority: NOR Component: general Assignee: k...@davidedmundson.co.uk Reporter: kde....@xapienz.ru CC: bhus...@gmail.com, plasma-b...@kde.org Application: plasmashell (5.5.4) Qt Version: 5.5.1 Operating System: Linux 4.4.0-10-generic x86_64 Distribution: Ubuntu Xenial Xerus (development branch) -- Information about the crash: After some period of inactivity (usually when I go to work or sleep) plasma crashes several times (3-5 times per 8 hours). Seems to be some problem with monitors. I have a laptop with HDMI monitor connected, laptop screen is disabled in KDE Settings. The stacktrace looks similar to bug #350994, but I don't have to do anything special to reproduce it. The crash can be reproduced sometimes. -- Backtrace: Application: Plasma (plasmashell), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
