Description David Block 2019-08-07 23:57:25 UTC

Application: systemsettings5 (5.12.8)

Qt Version: 5.9.5
Frameworks Version: 5.44.0
Operating System: Linux 4.15.0-55-generic x86_64
Distribution: Ubuntu 18.04.3 LTS

-- Information about the crash:
- What I was doing when the application crashed:
From terminal: sudo systemsettings5

- Custom settings of the application:
sudo

I previously tried to change the printer from color to grayscale, it wants a root user to confirm, and I have no idea what the root password is because I use sudo.

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".

Don't run GUI apps as root.

Comment 2 Kai Uwe Broulik 2019-08-08 07:55:25 UTC

However, it does print something to console, can you check what it printed before dying?

Thanks Kai,

I finally resolved the printer issue but the systemsettings5 bug still
persists (even when run without sudo).

Here's the result of launching systemsettings5 from the terminal as my
normal user:

Comment 4 Christoph Feck 2019-08-08 20:24:39 UTC

It looks like you updated NVIDIA driver or kernel without rebooting.
