Description Heinrich Seebauer 2018-03-19 12:08:54 UTC 
Application: systemsettings5 (5.8.7)

Qt Version: 5.6.2
Frameworks Version: 5.32.0
Operating System: Linux 4.4.114-42-default x86_64
Distribution: "openSUSE Leap 42.3"

-- Information about the crash:
Opened System Settings (as normal user)
Clicked on "Display and Monitor"

Similar ways to crash (always starting with system settings dialogue)
- workspace Theme
- application style/window docorations
- desktop bevaviour/desktop effects
- desktop bevaviour/activities
- startup and shutdown/login screen
- display and monitor
- multimedia/audio volume

Checked all items displayed on "Systems Settings" entry dialogue.
Application sometimes displayed a bug message dialoge, but most times did not even do that.

Backtrace is generated from "Display and Monitor" selection crash.

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".

Comment 1 Christoph Feck 2018-03-30 19:50:36 UTC 
Are you using the nvidia binary drivers?

If yes, when updating nvidia drivers, you must reboot your system. This is because every driver version comes with its own kernel module. If the driver cannot find the matching kernel module, Qt is not able to create OpenGL contexts, despite the driver announcing that it supports OpenGL.

If not, please run systemsettings5 from Konsole, and check the abort message.
Comment 2 Heinrich Seebauer 2018-04-03 07:48:32 UTC 
Moved on to kernel 4.4.120, did several bootups meanwhile.
Thank you very much for helping me out - next time I will check for updates of the kernel AND the graphics driver first.

I consider this one as closed (==resolved/fixed?)
