I just barely changed my theme in Manjaro linux. When I hit apply it kicked me out of settings. When I tried launch system settings again it just shows the loading circle and thats it. I have restarted my system multiple times and it still wont work. I tried the command systemsettings5 and that didn’t work either. All other apps launch perfectly.
Welcome to the forum!
It could be an incompatible theme. You either way haven’t told us what desktop environment you’re using, and what theme. Without that information, nobody’s going to be able to help you.
In kde “~/.config/kdeglobals” file “[KDE]” section change “widgetStyle=breeze” or delete kdeglobals file.
In Qt with qt5ct “~/.config/qt5ct/qt5ct.conf” file in “[Appearance]” chage “style=breeze” or delete file.
In Qt without qt5ct remove “~/.config/qt5ct/Trolltech.conf” file
In gtk2 remove “~/.gtkrc-2.0” file.
In gtk3 remove “~/.config/gtk3” folder.
Hello, I am using KDE Plasma 20.1.2. I don’t know what theme I used, I think it was called ‘Gently’. I would check which one i’m using but I can’t get into settings.
Try in konsole "cat ~/.config/kdeglobals |grep -i ‘widgetstyle=’ " command.
Hello, I tried that command and I don’t exactly understand what it did. I still can’t access my system settings though.( I’m still new to linux and I don’t know a lot about it yet.)
Here is what it popped up when I tried that command. I don’t know if I did it right. I tried to do the command without putting sudo first and nothing happened.
I did this exactly this sudo "cat ~/.config/kdeglobals |grep -i ‘widgetstyle=’ "
It popped this out.

[-u user] file …
I don’t know what it means. I wish you could upload screenshots, it would make things easier.
You don’t need sudo, only type :
cat ~/.config/kdeglobals |grep -i ‘widgetstyle=’
and press ENTER.
I did that command and it gave me this.
Run this, then be careful about applying compatible themes in the future
[note - this will select and apply the ‘global theme’ - so desktop and color themes etc will change]
lookandfeeltool -a org.kde.breeze.desktop
(breeze is just the plasma default … so its virtually guaranteed to be ‘working/good’)
Thank you, that seemed to work. I’ll be careful which themes I use from now on.
