Bug ID: 416991
Summary: Editing monitor layout, followed by tab switch
Product: systemsettings
Version: 5.17.5
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: jeremy.lin...@arm.com
Target Milestone: ---
Application: systemsettings5 (5.17.5)
Qt Version: 5.13.2
Frameworks Version: 5.66.0
Operating System: Linux 5.4.14-200.fc31.x86_64 x86_64
Distribution: Fedora 31 (Workstation Edition)
-- Information about the crash:
- What I was doing when the application crashed:
While docking my laptop (T450s) a good percentage of the time the screen's
aren't returned to their previous positions. In this case one was not showing
any video. System Settings->Display and Monitor->Display Config, and the
screens were randomly placed. When this happens I usually disable the two
screens, click outside the tab then back in (because frequently disabling the
screens results in it completely disappearing), and then re-enable and
re-position them. In this case it crashed when I clicked "input devices" IIRC.
It could be a dupe of one of the other tab switching ones, but I couldn't
compare the backtrace with this app easily.
-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
