Issue with Hyprland and Nix

[deephack1982]

Hello,

There is an issue with the flake.nix supplied where if you have installed hyprland from home manager the flake will then also make a system wide installation of hyprland from nixpkgs which in my case gives me 0.52.1 whereas I already have 0.53.1 installed from home manager. This causes a few different issues and stops hyprland from picking up my config and loading correctly. I simply forked the repo and removed hyprland from the flake and that made everything work again.

To get to my point I would suggest that baking the three different compositors into the flake seems like a bad idea as this kind of issue will occur. Surely we should leave it up to the user to install the compositor that they intend to use with the greeter? If you agree then I'm happy to make a PR with this change.

Hi mate, this is interesting I didn't think nix users installed via home manager mostly just programs.hyprland.enable = true, but error makes sense and definitely agree the flake should not be opinionated about compositor installation.

Happy for the PR if you want to make it.. are you thinking just removing environment.systemPackages with compositorPackage option that defaults to null for users who want the convenience can opt in?

You probably find that many people do go down the programs.x route. I'm using a bunch of home manager modules though to generate my hyprland config so need to do it this way.

I'll put something together shortly and link it here. Thanks for being open to it 👍

Yes I'll remove the systemPackages part and put in an option for the package if people want it.

I've done some work on my fork which I need to tidy up a bit before making a PR. However if you would like to try it out then you can do the following.

If you use a flake based config add this to your inputs.

sysc-greet = {
      url = "github:deephack1982/sysc-greet";
      inputs.nixpkgs.follows = "nixpkgs";
    };

Then pass sysc-greet as an output and add sysc-greet.nixosModules.default as a module for your NixOS config. Lastly inside your config use a stanza like this.

services.sysc-greet = {
    enable = true;
    compositor = "hyprland";
    settings = {
      theme = "tokyo-night";
    };
  };

To see what I mean in it's entirety you can check out my config here https://tangled.org/deephackontech.bsky.social/nixos-config

Yeah this works.
