Bug ID: 378416
Summary: Screen dark and plasma crash when laptop docked
Product: plasmashell
Version: 5.9.4
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: ddash.r...@gmail.com
CC: bhus...@gmail.com, plasma-b...@kde.org
Target Milestone: 1.0
Application: plasmashell (5.9.4)
Qt Version: 5.8.0
Frameworks Version: 5.32.0
Operating System: Linux 4.10.6-1-ARCH x86_64
Distribution (Platform): Archlinux Packages
-- Information about the crash:
- What I was doing when the application crashed:
I had put my laptop to sleep by closing the lid. Then I docked the laptop
without opening the lid. After docking, I opened the lid. The screen did not
come on. Most of the times that this happens, I have to force reboot.
Sometimes, when I undock, plasma crashes and the screen comes back on with the
login screen (all apps still running when I login).
The crash can be reproduced sometimes.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
