FreeVariable: did you install sysprof through environment.systemPackages? Looks like it might be required.

FreeVariable: for now, I have opened an issue https://gitlab.gnome.org/GNOME/sysprof/-/issues/112

Hello! I'm using NixOS with GNOME, and I use Nautilus as File Manager.

I set Tokyo Night Dark GTK theme (tokyo-night-gtk package) and it works well on GNOME windows like GNOME Tweaks and I tested it also on Mate and Cinnamon DEs and this GTK theme works.

I set this theme by:

  home-manager.users.${username} = { pkgs, ...}: {
    gtk = {
      enable = true;
      gtk3.extraConfig.gtk-decoration-layout = "menu:";
      theme = {
        name = "Tokyonight-Dark-B";
        package = pkgs.tokyo-night-gtk;
      };
      iconTheme = {
        name = "Tokyonight-Dark";
      };
      cursorTheme = {
        name = "Bibata-Modern-Ice";
        package = pkgs.bibata-cursors;
      };
    };

The problem is that this theme is not applied on Nautilus window that remains a light theme (I guess Adwaita).

How can I apply Nautilus GTK theme?
