I just installed KCacheGrind onto my WSL2 Ubuntu for profiling the performance of a program, but I can't stand the blinding light.
I've noticed that every time I run it through the terminal, there is the message Icon theme "breeze" not found. (but the program works just fine). Then I learned about KDE themes, but I don't want to install the whole KDE ecosystem. I just want to install a dark theme so that I can use KCacheGrind comfortably.
I found many KDE themes online available as GitHub repos. So I downloaded gnome-breeze which has the folder "Breeze-dark-gtk" consisting of a dark theme. In my understanding, all that is left to do is for me to figure out where exactly to put the files so that they are recognized as a theme. I've learned that they are to be stored in ~/.themes (or /usr/share/themes), but couldn't find more info on the exact directory structure. I have tried a bunch of guesses (such as mv gnome-breeze/Breeze-dark-gtk ~/.themes/breeze), but the theme is still not recognized.
I don't need to be able to switch between multiple themes. If I can trick KCacheGrind into thinking that a custom dark theme is the default theme and apply it to its GUI, that's all I want.
