Bug ID: 357578
Summary: Plasma crash after disconnecting external monitor
Product: plasmashell
Version: 5.5.2
Platform: openSUSE RPMs
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: s...@gmx.de
CC: bhus...@gmail.com, plasma-b...@kde.org
Application: plasmashell (5.5.2)
Qt Version: 5.5.1
Operating System: Linux 4.3.3-5.g008195a-default x86_64
Distribution: "openSUSE Tumbleweed (20160101) (x86_64)"
-- Information about the crash:
- What I was doing when the application crashed:
I have used an external projector to display Firefox content (Kahoot!).
Compositing is not enabled and the internal display was turned off. I'm using a
rather weak Asus eeePC 1015PED (Intel Atom N475) after all... After closing
Firefox and disconnecting the projector Plasma crashed.
The crash can be reproduced sometimes.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
