What happens? Nothing. Default themes.
Below are the options that I was able to find to set the GTK and Qt themes. For Qt, I want to use Kvantum because Materia looks perfectly consistent with GTK when I do.
The name strings are correct, I looked inside the packages.
I was told that home.sessionVariables is often not respected. Do I need to inject them into my shell, and have that managed with HM? If the issue is with GDM, how do I force it to use my environment? Do I have to make my window manager run a shell script on startup?
At the very least I would expect Thunar to be themed properly with the gtk attribute. But it is still white.
What about Qt icons? I see no option to set those, and I don’t know of an environment variable for it.
Excerpt of profile.nix:
home.packages = with pkgs; [
materia-kde-theme
libsForQt5.qtstyleplugin-kvantum
];
gtk.iconTheme.package = pkgs.papirus-icon-theme;
gtk.iconTheme.name = "Papirus-Dark";
gtk.theme.package = pkgs.materia-theme;
gtk.theme.name = "Materia-dark-compact";
xdg.configFile."Kvantum/kvantum.kvconfig".text = ''
[General]
theme=MateriaDark
'';
home.sessionVariables = {
QT_STYLE_OVERRIDE = "kvantum";
GTK_USE_PORTAL = 1;
};
