Bug ID: 455869
Summary: KDE / Entire System Crashes Randomly, No Confirmable
Pattern
Product: plasmashell
Version: 5.18.8
Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: justinf7...@gmail.com
CC: k...@davidedmundson.co.uk
Target Milestone: 1.0
Application: plasmashell (5.18.8)
Qt Version: 5.12.8
Frameworks Version: 5.68.0
Operating System: Linux 5.4.0-121-generic x86_64
Windowing system: X11
Distribution: Ubuntu 20.04.4 LTS
-- Information about the crash:
- What I was doing when the application crashed:
Most frequently occurs when playing back video and/or audio, but not
necessarily. The Discord application may or may not be related, also with
multimedia, including images, but always most frequently with video/audio.
Beyond that, no discernable reason or pattern to the crashes since sometimes
they may even occur when the computer is idle and I'm away.
- Unusual behavior I noticed:
Beforehand nothing unusual is occurring, CPU, RAM, and disk well under the
maximum stresses. After the crash, usually the screen halts, then goes blank or
reverts to the computer manufacturer logo that appears during boot or simply
goes black.
Once, every running program (including background and seemingly some drivers)
crashed one by one or rather, the system could no longer "find them", but that
seems to be a unique instance.
This appears to have been the only time it recovered from the crash.
- Custom settings of the application:
Several icons on the desktop, including some files. 3 sticky note widgets. 1
combo system load widget. 1 RAM & swap widget. 1 CPU widget. 1 weather widget.
1 KDE connect widget, default wallpaper.
- External hardware
System is installed on an external hard drive connected via USB. Also connected
is a 4x USB hub, with a wireless mouse, an optical drive, and a floppy drive
all connected.
The crash can be reproduced every time.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
