Various icons, from nm-applet and qBittorrent when set to autostart, to icons inside some GTK apps, fallback to a warning image, even if gtk.iconTheme has been set, and/or the icon theme has been installed via home.packages. Like this:
My Home Manager configuration:
# ...
gtk = {
enable = true;
cursorTheme = {
package = pkgs.vanilla-dmz;
name = "Vanilla-DMZ";
size = 24;
};
font = {
package = pkgs.dejavu_fonts;
name = "Dejavu Serif";
size = 12;
};
iconTheme = {
package = pkgs.libsForQt5.breeze-icons;
name = "Breeze";
};
theme = {
package = pkgs.libsForQt5.breeze-gtk;
name = "Breeze";
};
};
qt = {
enable = true;
platformTheme = "qtct";
# style = {
# package = pkgs.libsForQt5.breeze-qt5;
# name = "breeze";
# };
};
# ...
home.packages = with pkgs; [
brightnessctl

# ...
Currently the themes are set to Breeze. Neither did Adwaita work properly, though.
