Bug ID: 362148
Summary: Plasma crashes with multi-monitor setup
Product: plasmashell
Version: 5.6.3
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: kde-b...@kristiankoch.com
CC: bhus...@gmail.com, plasma-b...@kde.org
Application: plasmashell (5.6.3)
Qt Version: 5.6.0
Frameworks Version: 5.21.0
Operating System: Linux 4.5.1-1-ARCH x86_64
Distribution (Platform): Archlinux Packages
-- Information about the crash:
- What I was doing when the application crashed:
1.) Boot laptop and log into KDE
2.) Plugin second monitor
3.) KDE switches to second monitor (configured as main screen)
4.) Mouse pointer and taskbar(s) apear, but background stays black (right click
on background not possible)
5.) Fire up nvidia settings, try to change main screen back to laptop, but
nothing happens
6.) Try to deactivate second screen, Plasma segfaults
- Unusual behavior I noticed:
See 4.) & 5.) above. In general, Plasma crashes more or less regularly in my
multi-monitor setup when I plugin my second screen or switch between them.
However,the behaviour isn't always the same.
The crash can be reproduced sometimes.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
