NixOS Flake Home-Manager: there is no $XDG_RUNTIME_DIR/hypr directory

[Ziqi-Yang]

Recently I switched my configuration to use flake based hyprland configuration (before this I uesd hyprland on NixOS with home-manager, without Flake). However, after the switching, I cannot run hyprctl version and it says:

❯ hyprctl version
Couldn't connect to /run/user/1000/hypr/v0.39.1_1715424281/.socket.sock. (3)

Additional information:

❯ echo $XDG_RUNTIME_DIR/hypr
/run/user/1000/hypr
❯ ls /run/user/1000/hypr
ls: cannot access '/run/user/1000/hypr': No such file or directory
❯ ls /tmp/hypr

My configuration
Before:
in nixos module:

programs.hyprland.enable = true;

in home-manager module:

  wayland.windowManager.hyprland.enable = true;
  # and other configurations 

After:
in nixos module: (https://git.sr.ht/~meow_king/nixos-config/tree/0b99a556468159a23ac7406129bd6790346f29ef/item/hosts/meowos/default.nix#L144-147)

  programs = {
    hyprland = {
      enable = true;
      package = inputs.hyprland.packages.${pkgs.system}.hyprland;
    };
  };

in flake outupt (https://git.sr.ht/~meow_king/nixos-config/tree/0b99a556468159a23ac7406129bd6790346f29ef/item/hosts/default.nix#L27-54)

  nixosConfigurations = {
    meowos = lib.nixosSystem {
      system = "x86_64-linux";
      specialArgs = {inherit inputs outputs gVars mylib secrets;};
      modules = [
        ./meowos

        home-manager.nixosModules.home-manager {
          home-manager = {
            useGlobalPkgs = true;
            useUserPackages = true;
            users.${gVars.username} = import ../home/linux/desktop-develop.nix;
            extraSpecialArgs = { inherit inputs gVars mylib secrets; };
            sharedModules = [
              hyprland.homeManagerModules.default
            ];
          };
        }
      ];
    };
  };

the configuration inside home-manager module doesn't change: (https://git.sr.ht/~meow_king/nixos-config/tree/0b99a556468159a23ac7406129bd6790346f29ef/item/home/linux/desktop/hyprland.nix#L37)

Thank you very much for your help!

0.39.1 is the version in Nixpkgs. The flake has 0.40.0, which is the only version (currently) that includes the $XDG_RUNTIME_DIR change. Are you positive your hyprland input is up to date? Try running a nix flake update.

Sorry for the late reply. Just now I just rechecked my configuration, and I find in my configuration, my login manager actually uses pkgs.hyprland as its input, which causes the problem. Thank you very much!
