Bug ID: 461439
Summary: Application Appearance - KDE apps - systemsettings5
crash
Classification: Applications
Product: systemsettings
Version: 5.18.7
Platform: unspecified
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
Application: systemsettings5 (5.18.7)
Qt Version: 5.12.8
Frameworks Version: 5.68.0
Operating System: Linux 5.15.0-52-generic x86_64
Windowing system: X11
Distribution: Zorin OS 16.2
-- Information about the crash:
- What I was doing when the application crashed:
Attempting to find a way to theme the KDE apps which refuse to use Breeze Dark.
Unable to solve the theming for Settings application and (I think) all other
native KDE apps - I'm not even able to be sure if the Application Appearance of
Settings is what's preventing this - I am 100% new to KDE and I really only
have ~<1yr linux experience. Please educate me if I need it.
Per this post: , I have attempted to properly install and use qt5ct through
Synaptic and set appropriate environment variables:
`$ export QT_QPA_PLATFORMTHEME=qt5ct`
`$ export QT_STYLE_OVERRIDE=qt5ct`
or,
`$ QT_QPA_PLATFORMTHEME=qt5ct`
`$ QT_STYLE_OVERRIDE=qt5ct`
or,
`QT_STYLE_OVERRIDE=qt5ct && QT_QPA_PLATFORMTHEME=qt5ct`
Things like `unset QT_THEME_OVERRIDE` do not work either.
Each time I check the work by running:
`$ env`
The changes had never been made it seems. This persists through reboot,
specifically after running `QT_STYLE_OVERRIDE=qt5ct &&
QT_QPA_PLATFORMTHEME=qt5ct`
---
Editing /etc/environment as `sudo` does successfully acheive my desired results
when opening qt5ct and Settings as sudo in terminal...
qt5ct recognizes the environment variable I managed to set and does not request
that I remove the QT_STYLE_OVERRIDE any longer.
I was also able to set the QT_QPA_PLATFORMTHEME=qt5ct variable as instructed
because qt5ct longer asked me to add the variable.
Now, when opening `sudo systemsettings5`, the entire problem disappears -
theming it to the Breeze Dark as set under `sudo qt5ct`.
I want to have this ability to theme the KDE apps without requiring sudo login
- like when a user opens the Meta menu and clicks on the 'System Settings'
application entry that appears.
`$ grep -r 'QT_STYLE_OVERRIDE' returns no likely places to look for another
non-root profile/theme location.`
Please help.
The crash can be reproduced every time.
