Bug ID: 448747
Summary: KDE Neon crashes screen when initializing and keeps
showing a buggy screen (not black screen)
Product: plasmashell
Version: 5.23.5
Platform: Neon Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: jhm...@protonmail.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
Application: plasmashell (5.23.5)
Qt Version: 5.15.3
Frameworks Version: 5.90.0
Operating System: Linux 5.13.0-27-generic x86_64
Windowing System: X11
Distribution: KDE neon User - Plasma 25th Anniversary Edition
DrKonqi: 5.23.5 [KCrashBackend]
-- Information about the crash:
- What I was doing when the application crashed:
I was using the Pc and I updated through Discover, and I kept using the PC
normally, when I finished some works, I left and I kept the PC on for 6 hours.
I used it normally when I came back for 4 hours and then I turned it off.
- Unusual behavior I noticed:
The screen started crashing looking like a broken tv screen when there's no
signal, once I turned it on again, 3 hours later.
The crash can be reproduced every time.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
