Bug ID: 463122
Summary: Plasma Crashes When Switching KVM Switch
Classification: Plasma
Product: plasmashell
Version: 5.25.5
Platform: Kubuntu
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: mwate...@gmail.com
CC: k...@davidedmundson.co.uk
Target Milestone: 1.0
Application: plasmashell (5.25.5)
Qt Version: 5.15.6
Frameworks Version: 5.98.0
Operating System: Linux 5.19.0-26-generic x86_64
Windowing System: X11
Distribution: Ubuntu 22.10
DrKonqi: 5.25.5 [KCrashBackend]
-- Information about the crash:
Behavior is very repeatable.
KVM switch does not do EDID emulation, and is connected to a DP MST hub. When
switching back to machine running Kubuntu, monitors are often improperly
configured, so resetting orientation and positions with xrandr is required.
The crash can be reproduced every time.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
