Hi everyone,

I have switched to use Breeze-dark theme, and generally it is working fine. But when I start synaptics, it displays in normal Breeze theme. The same happens if I start a program from konsole with sudo (e.g. partitionmanager). Any hints how to change this?

Operating System: KDE neon 5.19
KDE Plasma Version: 5.19.4
KDE Frameworks Version: 5.73.0
Qt Version: 5.14.2
Kernel Version: 5.4.0-42-generic
OS Type: 64-bit
Processors: 4 × Intel® Core™ i5-7200U CPU @ 2.50GHz
Memory: 7.6 GiB of RAM
Graphics Processor: GeForce 940MX/PCIe/SSE2

Mmmm... did you tweak the GNOME/GTK Application Style to explicitly choose the dark theme?

You could set root apps to use the dark theme in root settings:

sudo -i systemsettings5

I had problems with extra large fonts in some sudo apps (Partition Editor) and setting them to the same size as user fixed it.

+1 awesome!
and here I was logging in as root user to make these system changes
thank you for that tip!

Funny thing is, if I do sudo -i systemsettings5, then I cannot change gtk themes - the module just doesn't show up... Also, systemsettings appear in normal Breeze theme, although I have chosen Breeze-dark...

Yes, I did that, and it works with normal applications, but not with applications that use sudo mode (like synaptics)

Did you ever figure this out? Same issue, still light theme after choosing dark, the module for GTK settings doesn't exist when run as root..

Good news... some apps, like synaptic will eventually, with newer versions of plasma+frameworks, conform
Before that discovery however, I would tweak synaptic (at least) to use a custom font (in Settings > Prefs)

Paste in /etc/environment
XDG_CURRENT_DESKTOP="KDE"

Just

Code: Select all

sudo cp -R {~,/root}/.config/gtk-3.0

.

I tried everything what was suggested here and Krusader run in root mode still seems to use "Breeze" instead of "Breeze-Dark". I also made sure that ~/.kde/share/config/kdeglobals is the same as /root/.kde/share/config/kdeglobals. When I run "sudo -i systemsettings5" currently selected theme is "Breeze-Dark", but the window with system settings is bright. I tried to choose "Breeze" and then "Breeze-Dark" again, but after applying the settings I got this in the console:

Code: Select all

BTW: I managed to make Synaptic Package Manager run in privileged mode follow "Breeze-Dark", but Krusader (Qt) is still "Breeze". Any idea what else can be done?
