KDE Desktop - Setting Up a Dark Theme GLOBALLY

One more question:

How an everyman user can change a Dark Theme (ex Breeze Dark) GLOBALLY. I mean for every visual aspect of the system.

I have already make some obscure changes but some windows appear in OpesSuse default theme (ie Ya… istaller, etc).

Thanks in advance as usual.

for gtk apps make sure you have breezy-gtk (for default plasma) or breeze-gtk (plasma 5.6 or higher).
Then set this to be used for gtk apps.

Some apps - like chrome - would need to have a specific theme installed.

Yast installer runs as root - so you’d need to specify a dark theme for root as well - but even then, I’m not sure that yast follows any user set theme - it may be a fixed theme.

Thanks. I got it.
I have been wondering what was the purpose of those two GKT options.

How one can make a theme applied to root, as you mention?
