Bug ID: 468952
Summary: plasmashell crashes after logging in and reconnecting
display
Classification: Plasma
Product: plasmashell
Version: 5.27.4
Platform: Manjaro
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: waqar....@gmail.com
CC: k...@davidedmundson.co.uk
Target Milestone: 1.0
SUMMARY
My PC is basically a laptop with an external display. I left the screen locked
for about an hour or so and then returned to my PC. Moved the mouse, screen
turns on and I tried to type my password in the lockscreen which had no effect.
Disconnected the external display => then typed in the password which worked =>
immediately reconnected the display cable => plasmashell crashed. I wasn't able
to find a bug with a similar backtrace so opened this one.
Core was generated by `/usr/bin/plasmashell --no-respawn'.
Program terminated with signal SIGSEGV, Segmentation fault.
