Can I change a certain application's GTK theme that would differ from the system set one?
I'd like to change Spotify's theme to be Qogir-black, but keep everything else on Qogir-light (two different theme folders) I want spotify window to have a black header.
Now it looks like this with a white header:
When I change the system theme (in GNOME Tweaks) to dark, the Spotify header changes. So the problem is not in the theme.
I tried changing the
/usr/share/applications/spotify.desktop file to this:
[Desktop Entry] Type=Application Name=Spotify GenericName=Music Player Icon=spotify-client #TryExec=spotify Exec=env GTK_THEME=Qogir-dark spotify %U Terminal=false MimeType=x-scheme-handler/spotify; Categories=Audio;Music;Player;AudioVideo; StartupWMClass=spotify
I followed this tutorial here but it didn't do the thing.
