"Hyprland was started without start-hyprland..." error on startup when using NixOs and withUWSM

[rickyelopez]

Hello!

I've started getting this error on startup since updating the hyprland flake to rev 0467be86b18cfc324fab04afbd40fe9ef80f7fa9. Not sure that that's the rev that introduced it, as I don't update to every rev.

I think this makes sense since uwsm in nixos is configured to run the Hyprland binary directly, but is this intentional? I've tried locally patching my nix config to run start-hyprland from UWSM instead (with programs.uwsm.waylandCompositors.hyprland.binPath = lib.mkForce "${hyprlandPackage}/bin/start-hyprland";), but then I get a warning about XDG_CURRENT_DESKTOP being managed externally. I haven't noticed any issues despite this warning (yet, at least). Is this the correct solution? Or should UWSM continue to run Hyprland directly, and then maybe a Hyprland gets a patch to suppress this error in this case?

I notice the same 👍🏾

Have the same, I have :
programs.uwsm.waylandCompositors.hyprland.binPath = lib.mkForce "/run/current-system/sw/bin/start-hyprland";

and in greetd i have: command = "${lib.getExe config.programs.uwsm.package} start -e -D Hyprland hyprland-uwsm.desktop";

Got same error, had to revert to Hyprland 0.52.0 built from branch unknown at commit f11cf6f1de708b6b3811788e8ff7984ff05a9546

A search for "start-hyprland" site:hypr.land only returns one result right now: https://wiki.hypr.land/Getting-Started/Master-Tutorial/#launching-hyprland. I also have started seeing this, but without any adverse affects yet as far as I can tell.

I am also on NixOS running hyprland via flake from the development branch, I have the following nix config relating to hyprland:

{
  inputs, config, lib, pkgs,
  ...
}: {
  inherit (pkgs.stdenv.hostPlatform) system;

  imports = [ inputs.hyprland.nixosModules.default ];

  nix.settings = {
    substituters = ["https://hyprland.cachix.org"];
    trusted-substituters = ["https://hyprland.cachix.org"];
    trusted-public-keys = ["hyprland.cachix.org-1:a7pgxzMz7+chwVL3/pzj6jIBMioiJM7ypFP8PwtkuGc="];
  };

  programs = {
    hyprland = let
      hyprpkgs = inputs.hyprland.packages."${system}"
    in {
      enable = true;
      withUWSM = true;
      package = hyprpkgs.hyprland;
      portalPackage = hyprpkgs.xdg-desktop-portal-hyprland;
      settings = { ... };
    };
  };
}

I am getting the same error.

I'm currently working on this issue. The simplest way to get it to work is to set withUWSM = false, not set programs.uwsm.enable = true, but instead set

  environment.systemPackages = [ pkgs.uwsm ];
  systemd.packages = [ pkgs.uwsm ];
  environment.pathsToLink = [ "/share/uwsm" ];

Also don't forget to use dbus-broker if you aren't doing it explicitly already.

To use the hyprland-provided hyprland-uwsm.desktop, the derivation's cmakeFlags have to be modified to

-        "NO_UWSM" = true;
+        "NO_UWSM" = !withSystemd;

If you use greetd, the above is not needed, you only have to use uwsm start -eD Hyprland hyprland.desktop.

Alternatively, @Gako358's solution should work.

a warning about XDG_CURRENT_DESKTOP being managed externally

Why is such warning even needed? What if someone makes a session using Hyprland with their own desktop names, either including Hyprland or not?
