Bug ID: 437913
Summary: Frequent crashes when Connected to External Monitor
Product: plasma-systemmonitor
Version: 5.21.4
Platform: Kubuntu Packages
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: general
Assignee: ksysguard-b...@kde.org
Reporter: pang...@outlook.com
CC: ahiems...@heimr.nl, plasma-b...@kde.org
Target Milestone: ---
SUMMARY
The laptop repeatedly crashes when connected to the external monitor. Did not
do so in the previous version of Kubuntu.
STEPS TO REPRODUCE
1. Go to 'System Settings' → Applications style → change Global theme.
2. Alternately, Put the laptop to 'Sleep' when connected to the external
monitor. It said once the lock screen is broken. Now I don't see the message,
it just freezes and a forced shutdown is needed.
3. The only way to resolve the freeze crash is a reboot.
OBSERVED RESULT
Crash.
EXPECTED RESULT
To work like the previous version.
