Bug ID: 511445
Summary: plasmashell crash when multiple displays are attached
at startup
Classification: Plasma
Product: plasmashell
Version First 6.5.1
Reported In:
Platform: openSUSE
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: generic-crash
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: 1.0
Created attachment 186372

Backtrace of crash event, suggests SEGV as cause of crash
SUMMARY:
After upgrading from Plasma 6.5.0 to 6.5.1, when starting session while laptop
(Thinkpad T470) is docked, all displays, including the internal screen stay
blank. Only after detaching from dock, the crash handler shows up, telling me,
the user, that plasmashell has crashed. After looking at the crash-log, it says
that plasmashell is terminated due to a segmentation fault (SIGSEGV).
STEPS TO REPRODUCE
1. Run openSUSE Tumbleweed with Plasma 6.5.1, have laptop docked on startup
2. Launch Wayland session at log-in
OBSERVED RESULT
Black screen on all displays, no change until laptop is detached from dock.
Only after detachment, plasmashell restarts.
EXPECTED RESULT
Usual launch of plasmashell + KWin, like on 6.5.0.
(After rollback to 6.5.0, the problem no longer persists.)
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: openSUSE Tumbleweed, KDE Plasma 6.5.1
Kernel: 6.17.5-1-default (64-bit)
KDE Plasma Version: 6.5.1
KDE Frameworks Version: 6.19.0
Qt Version: 6.10.0
Graphics platform: Wayland
ADDITIONAL INFORMATION
Attached is the coredump obtained from "coredumpctl debug plasmashell -A "-ex
bt -ex quit" |& tee backtrace.txt".
I noticed similarities with Bug 511428, even though I do not use i3 as WM, but
KWin as intended.
