Bug ID: 385321
Summary: Screen locker 'unable to unlock, use loginctl instead'
randomly when system is locked
Product: plasmashell
Version: 5.10.5
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: kde...@mnetwork.co.kr
CC: plasma-b...@kde.org
Target Milestone: 1.0
Application: plasmashell (5.10.5)
Qt Version: 5.9.1
Frameworks Version: 5.38.0
Operating System: Linux 4.13.4-1-hardened x86_64
Distribution (Platform): Archlinux Packages
-- Information about the crash:
- What I was doing when the application crashed:
I pressed session lock shortcut key. Monitor turned off after screen timeout.
Waited for random time.
- Unusual behavior I noticed:
Even if screen locker does not crash until I resume to seat and login, I can
see compositor has been crashed and stopped updating (e.g., time display)
entries on desktop panels. Using XRender instead of OpenGL composition stops
compositor crash issue. (But still crashes screen locker)
- (Maybe) related kernel log
