Bug ID: 411575
Summary: Desktop when black then back
Product: plasmashell
Version: 5.16.4
Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: sunxuanmail...@163.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
Application: plasmashell (5.16.4)
Qt Version: 5.12.2
Frameworks Version: 5.61.0
Operating System: Linux 5.0.0-27-generic x86_64
Distribution: Ubuntu 19.04
-- Information about the crash:
- What I was doing when the application crashed:
Everytime after startup, the desktop background and task manager bar go black
and back. Then a crash notice pops up says plasma-workspace has crashed.
- Unusual behavior I noticed:
It seems to happen when changing wallpaper automatically. I am using win10 and
kubuntu dual boot and store wallpaers in ntfs partitions. This happens almost
everytime after a short period after startup using a single monitor, but
somehow when I use dual monitors it crashes less often. This starts to happen
back to 19.04, and when I tried to report, the crash handler complained no
debug symbols even when I already installed plasma-workspack-dbgsym. Last time
I checked, the debug symbol package is still broken.
The crash can be reproduced every time.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
