Application: systemsettings5 (5.18.4) Qt Version: 5.12.8 Frameworks Version: 5.68.0 Operating System: Linux 5.4.0-54-generic x86_64 Windowing system: X11 Distribution: Ubuntu 20.04.1 LTS -- Information about the crash: - What I was doing when the application crashed: I had Firefox and Sublime Text 3 open and wanted to look something up. Since the newly opened window (Dragged a Tab away from main window) was sent to a different activity I tried to go into the settings in order to adjust the window rules. However when opening the settings program in any way (terminal, App Launcher with mouse or keyboard or search bar) it crashes instantly and I get a notification. As soon as I click the "restart" button on the notification it crashes again and a new notification pops up. I will try a reboot, but maybe there is a bug hidden somewhere that causes this (edge conditions, heisenbugs) or it's the all dreaded side-effects. Hopefully this is useful to someone. If not please disregard it. The crash can be reproduced every time. -- Backtrace: Application: System Settings (systemsettings5), signal: Aborted Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Gotta restart the machine as your graphics drivers have been updated. *** This bug has been marked as a duplicate of bug 375913 ***
(In reply to Nate Graham from comment #2) > Gotta restart the machine as your graphics drivers have been updated. > > *** This bug has been marked as a duplicate of bug 375913 *** This resolved my issue although I can not understand how this problem have been with me for weeks and now it solves itself. I shutdown the computer every night and it would be a rather unbelievable coincidence that my graphics drivers are updated during same session as I am entering the system settings. But to be honest maybe I haven't tried to enter the settings that often and the error message is more likely remember vs. successful opening of the program. Never the less Thank you for your input.
