Bug ID: 416455
Summary: Plasma on Wayland crashes when disconnecting external
display (DisplayPort via Thunderbolt)
Product: plasmashell
Version: 5.17.5
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Target Milestone: 1.0
Application: plasmashell (5.17.5)
Qt Version: 5.14.0
Frameworks Version: 5.66.0
Operating System: Linux 5.5.0-rc5-1 x86_64
Distribution: "Arch Linux"
-- Information about the crash:
- What I was doing when the application crashed:
Disconnected the USB-C hub that a display is connected to via DisplayPort. It's
an XPS 13 9370, which I think emulates an additional DisplayPort.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
