Bug ID: 372751
Summary: Disconnecting from an HDMI port crashes plasma shell
Product: plasmashell
Version: 5.8.3
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected]
Target Milestone: 1.0
Application: plasmashell (5.8.3)
Qt Version: 5.7.0
Frameworks Version: 5.28.0
Operating System: Linux 4.8.9-1-MANJARO x86_64
Distribution: "Manjaro Linux"
-- Information about the crash:
- What I was doing when the application crashed:
Diconnected the laptop from a screen.
- Unusual behavior I noticed:
Every time the laptop is disconnected from a screen that's connected via HDMI,
either a crash occurs or the panel disappears until a reboot or the displays
are reconnected and then disabled.
The crash can be reproduced every time.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
