Bug ID: 412883
Summary: kwin crashing when waking up from supend
Product: kwin
Version: 5.16.5
Platform: Neon Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: softw...@glockenstein.de
Target Milestone: ---
Application: kwin_x11 (5.16.5)
Qt Version: 5.13.1
Frameworks Version: 5.62.0
Operating System: Linux 4.15.0-65-generic x86_64
Distribution: KDE neon User Edition 5.16
-- Information about the crash:
this happens since some months, not every wake up but very often.
since two or three weeks I have also problems when suspending.
monitors will be suspended but cpu is still running.
after wakeup and re-suspening it works most of the time,
until it crashes again.
I did count yet, but I think every third suspend fails.
I did not changed hardware before the problems arised.
The crash can be reproduced sometimes.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
