Bug description

There is no way to start systemd service on NixOS, as it should be done through config.

For example keyd:

System info

- LACT version: 0.5.4
- GPU model: RX 580 8GB
- Kernel version: 6.6.28 
- Distribution: NixOS Unstable

You should report this to the nix package maintainer, it's not packaged here.

Yes, please open an issue in Nixpkgs instead. This one can be closed.

I've written myself a custom module: https://github.com/Atemu/nixos-config/blob/2aedffdf2ec295a60c7b0f27074333d2418ad11c/modules/lact/module.nix that you can use in the mean time. I've been wanting to upstream that now that I tested it a little for myself.

I sent an email to the package maintainer informing them of this thread, so maybe it'll be fixed.
In the meantime, I've added this to my config to get it working:

systemd.services.lactd = {
after = [ "multi-user.target" ];
description = "AMDGPU Control Daemon";
wantedBy = [ "multi-user.target" ];
serviceConfig = {
ExecStart = ''${pkgs.lact}/bin/lact daemon'';
Nice = "-10";
};
};

Please just create a feature request on the Nixpkgs issue tracker. As a package maintainer myself, I'd also prefer a public discussion rather than an email.

The MVP to get the lact daemon to run are these lines:
