Bug ID: 378358
Summary: Powering down 4k screen while locked crashed
Product: plasmashell
Version: 5.7.5
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: k...@kolivas.org
CC: bhus...@gmail.com, plasma-b...@kde.org
Target Milestone: 1.0
Application: plasmashell (5.7.5)
Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.10.0-ck1+ x86_64
Distribution: Ubuntu 16.10
-- Information about the crash:
- What I was doing when the application crashed:
I had locked the session (associated with a 4k monitor) with the screenlocker
and once it was locked I powered down the monitor. When powering on the monitor
and unlocking it, only one side powered up (4k screens are two virtual
monitors) and on putting the password in plasma had crashed.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
