I’m unable to successfully install a default, minimal xmonad system using nixos 24.11.
Expected behavior: xmonad works out of the box as per XMonad - NixOS Wiki
Actual behavior: system boots to xmonad, but configuration file fails to compile
My system definition is a flake.nix:
{
description = "A simple NixOS flake";
inputs = {
nixpkgs.url = "github:NixOS/nixpkgs/nixos-24.11";
kmonad = {
url = "git+https://github.com/kmonad/kmonad?submodules=1&dir=nix";
inputs.nixpkgs.follows = "nixpkgs";
};
};
outputs = { self, nixpkgs, kmonad, ... }@inputs: {
nixosConfigurations.myhost = nixpkgs.lib.nixosSystem {
system = "x86_64-linux";
modules = [
./configuration.nix
kmonad.nixosModules.default
];
};
};
}
that invokes a configuration.nix (whose xmonad definition is taken from the wiki) (I commented out everything irrelevant):
{ config, lib, pkgs, ... }:
{
#enable flakes
#hardware config import
#boot loader/lvm stuff
services.xserver = {
enable = true;
windowManager.xmonad = {
enable = true;
enableConfiguredRecompile = true;
config = builtins.readFile ./xmonad.hs;
enableContribAndExtras = true;
};
};
#libinput stuff
#network/timezone/locale stuff
#kmonad service
#syncthing stuff
#sound stuff
#emacs stuff
#user definition
#system packages (no ghc, xmonad, or haskell-related packages)
programs.direnv.enable = true;
#system state version suff
}
with an xmonad.hs:
import XMonad
import XMonad.Config.Desktop
main = xmonad desktopConfig
{ terminal = "ghostty"
}
The system boots to a display manager and then xmonad, but journalctl -t xmonad shows errors:
