Bug ID: 436367
Summary: kwin_wayland crashes occasionally when enabling
monitor
Product: kwin
Version: 5.21.4
Platform: openSUSE RPMs
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: alo...@gmx-topmail.de
Target Milestone: ---
SUMMARY
I was running a Wayland session with an external monitor connected and the
laptop lid closed, so the external monitor was the only output. When I opened
the lid, kwin_wayland aborted.
STEPS TO REPRODUCE
1. Connect external screen
2. Close lid
3. Open lid
OBSERVED RESULT
kwin_wayland aborts and crashes.
EXPECTED RESULT
kwin_wayland continues running.
SOFTWARE/OS VERSIONS
Windows:
macOS:
Linux/KDE Plasma:
(available in About System)
KDE Plasma Version: 5.21.4
KDE Frameworks Version: 5.81.0
Qt Version: 5.15.2
ADDITIONAL INFORMATION
I got the same crash in a slightly different situation as well [1]. There, the
laptop monitor was black when I opened the lid, and the crash happened when I
tried to enable the internal monitor from system settings.
