Bug ID: 458197
Summary: Plasma Crashes after login
Product: plasmashell
Version: 5.25.4
Platform: Neon Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: kalaban...@gmail.com
CC: k...@davidedmundson.co.uk
Target Milestone: 1.0
Application: plasmashell (5.25.4)
Qt Version: 5.15.5
Frameworks Version: 5.96.0
Operating System: Linux 5.15.0-46-generic x86_64
Windowing System: X11
Distribution: KDE neon User - 5.25
DrKonqi: 5.25.4 [KCrashBackend]
-- Information about the crash:
Plasma crashes immediately after I login. I am presented with a black screen.
Plasma crashes again everytime I restart it with "kstart plasmashell". The
crash is reproduced every time I login and every time I restart plasmashell.
The first crash happened when I tried to use the present windows effect; the
desktop froze, I rebooted the laptop and plasma now crashes every time.
I can open applications with KRunner and desktop effects such as present
windows still work. I have no panels and no wallpaper.
Plamsa style: Breeze Dark
Application style: Breeze
The crash can be reproduced every time.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
