nixos/tuigreet: Unrecognized option config

[adamzwakk]

Nixpkgs version

• Unstable (25.11)

Describe the bug

When trying to boot to tuigreet through greetd, it fails to start saying it doesnt have an option called 'config'. Using the normal greetd.tuigreet on stable 25.05 doesn't have this issue.

Steps to reproduce

Here is my config for services.greetd

services.greetd = {
    enable = true;
    package = pkgs.greetd.tuigreet;
    settings = {
      default_session = {
        command = "${pkgs.greetd.tuigreet}/bin/tuigreet --time --cmd hyprland";
        user = "greeter";
      };
    };
  };

Expected behaviour

tuigreet should start up

I seem to have fixed this with not specifying tuigreet as my package, even though I specified greetd.tuigreet before. /shrug

services.greetd = {
    enable = true;
    settings = {
      default_session = {
        command = "${pkgs.tuigreet}/bin/tuigreet --time --cmd hyprland";
        user = "greeter";
      };
    };
  };

gets me in now, sorry for the issue!

[acid-bong]

Yes, that was the problem. package options are to replace the main package itself, in this case — Greetd. Tuigreet isn't a replacement for Greetd, it's an auxiliary program.

services.greetd.package is supposed to only have modifications of Greetd or (by default) the original Greetd derivation, not auxiliary programs

[adamzwakk]

Yup, figured that was it. Def one of those times where I spent an hour or so banging my head on my desk wondering why I can't boot and it was something very simple. Thanks for the confirmation/explanation, I appreciate it!
