Bug ID: 416005
Summary: Crash while adjusting monitor layout and refresh rate
in kscreen
Product: KScreen
Version: 5.17.4
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: kcm
Assignee: kscreen-bugs-n...@kde.org
Reporter: arca...@ivanov.biz
Target Milestone: ---
Application: kcmshell5 (5.17.4)
Qt Version: 5.12.5
Frameworks Version: 5.64.0
Operating System: Linux 5.4.8-200.fc31.x86_64 x86_64
Distribution: "Fedora release 31 (Thirty One)"
-- Information about the crash:
- What I was doing when the application crashed:
Trying to enable and arrange external TB3 monitors. The monitors would list,
but would not enable. While selecting refresh rate, the dialog crashed.
- Unusual behavior I noticed:
KScreen on occasion fails to enable the monitors, i.e. apply doesn't do
anything, even though the monitor configuration/status does not get reset after
failure to apply.
-- Backtrace:
Application: System Settings Module (kcmshell5), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
