Bug ID: 395706
Summary: Dual monitor + wayland crash
Product: plasmashell
Version: 5.13.1
Platform: Neon Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: tom.mago...@gmail.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
Application: plasmashell (5.13.1)
Qt Version: 5.11.0
Frameworks Version: 5.47.0
Operating System: Linux 4.13.0-45-generic x86_64
Distribution: KDE neon User Edition 5.13
-- Information about the crash:
System: Dell XPS laptop with connected external monitor.
- What I was doing when the application crashed:
Log in to kde using plasma wayland session.
After a few seconds the laptop display freezes, but the external monitor loads
the kde desktop.
The System Compositor dialog is launched.
Crash report icon displayed in system tray (used to generate this bug report).
The system display dialog reports the laptop monitor as disabled, the external
monitor as enabled.
This crash also happens on another Dell XPS laptop of mine. I first noticed the
issue with the release of plasma 5.12 LTS, and it continues to be an issue in
5.13.1
The crash can be reproduced every time.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
