Hello. I released a new version of my theme changing app for Linux.
It adds the feature to (force) set the theme of gnome libadwaita apps without libadwaita patches, among other minor tweaks. Besides that, it can change GTK2/3/4, Kvantum, icon and cursor themes, GTK CSS and some appearance settings across GUI frameworks.
Hope this is useful.
Thanks for checking.
I just checked as well and on my system (arch, xfce) the file exists but it’s a symlink, created by a theme I tried but doesn’t exist on my system anymore (“qogir-gtk-theme-git”). After removing the symlinks it works.
I clicked apply in the app and a gtk.css and settings.ini files was created. The gtk.css file it’s empty. Is that the intended behavior?
If you selected the adwaita theme, yes, there will be no css written
