NixOS Emacs

Henrov's Literate System Configuration

Introduction

Screenshot

This literate document describes and generates the configuration for the systems in this repository. It contains source blocks that are exported into individual files using Emacs Org modes tangling mechanism. The exported files are then evaluated as a NixOS flake to produce an immutable system configuration.

This repository currently includes configuration for:

traveldroid — main workstation/laptop

To generate the Nix files, open this file in Emacs and run M-x org-babel-tangle.

Alternatively, run the following from the command line:

emacs README.org --batch -f org-babel-tangle

Once the Nix files are generated, deploy using:

nixos-rebuild switch --flake .#<machine>

Other files in this repo include:

flake.lock for pinning input versions.

assets/* for non-Nix-managed artifacts such as images and wallpapers.

#- secrets/secrets.yaml for encrypted secrets edited using sops.

Generated outputs should not be edited directly. A CI workflow can tangle and commit generated outputs when they differ.

Emacs + Org + Tangle

[https://www.gnu.org/software/emacs/ is used as the editor and execution environment for this literate configuration.

[https://orgmode.org/ provides the document structure and the source block execution model used here.

Tangling exports source blocks from this Org document into the corresponding configuration files.

  • References of the form <<code-id>> are noweb placeholders that are expanded from other blocks during tangling.

Nix & NixOS

[https://nix.dev/ is used to define packages, environments, and configuration as pure expressions.

[https://nixos.org/ evaluates Nix expressions into a complete system configuration that can be applied by rebuild operations.

Repository layout and folder conventions

This repository contains system modules, user modules, and configuration fragments. The following directories are treated as separate layers: ./configuration (NixOS modules), ./home (Home Manager modules), and ./assets/conf (configuration fragments referenced or deployed by the modules).

To keep navigation consistent, the same internal substructure is used in all three locations. Each layer keeps its role; only the internal grouping is standardized.

Shared domain folders

  • core/ base settings and common infrastructure
  • desktop/ graphical session, compositor, UI components, and integration
  • apps/ application enablement and application-level configuration
  • services/ background services and daemons
  • security/ secrets handling and security-related configuration
  • dev/ developer tooling and editor configuration

I use nix flakes which means that the entry point for the nix evaluation is a file called flake.nix which has two parts (among other things)

  {
    inputs: # describes the function input, consisting mainly of package sources
    outputs: # what the function outputs, a nixos configuration in our case
  }

Nix flakes is still behind an experimental flag, but it is de facto the standard by most of the community. Flakes allow us to pin the input package versions using a flake.lock file. This prevents unwanted and surprise updates when rebuilding without changing the configuration.

Configuration Variables

I have a bunch of constant strings that I would rather put in a file. Thats what user.nix is. The values are imported at the beginning and are available to almost all the functions being called to configure the system.

  {
    system = "x86_64-linux";
    username = "henrov";
    stateVersion = "25.11";
    locale = "sv_SE.UTF-8";
  }

Flake Inputs

The inputs for my system's configuration are very simple

  1. nixpkgs - the main nix repository of packages. Its huge and growing. Pinned to the unstable release channel. Sometimes pinned to a specific commit because unstable broke something and the fix hasn't made it into the release yet.
  2. home-manager - a nix module that helps keep track of user specific dotfiles and configurations as part of my nix config.
  3. emacs-overlay - this has more configuration options and generally a newer emacs available provided by the community.
  1. catppuccin - nix module that allows everything to be catppuccin themed.
  {
    description = "Henrov's nixos configuration";

    inputs = {
      nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable";

      home-manager = {
        url = "github:nix-community/home-manager";
        inputs.nixpkgs.follows = "nixpkgs";
      };

      emacs-overlay = {
        url = "github:nix-community/emacs-overlay";
        inputs.nixpkgs.follows = "nixpkgs";
      };

#      sops-nix = {
#        url = "github:Mic92/sops-nix";
#        inputs.nixpkgs.follows = "nixpkgs";
#      };
#
      catppuccin = {
        url = "github:catppuccin/nix";
        inputs.nixpkgs.follows = "nixpkgs";
      };
    };

    <<flake-outputs>>
  }

Flake Output

├── flake.nix ├── user.nix

Now that the inputs are ready, the outputs define what the system will actually look like. I also define the machines that this configuration specifies early on. Finally, I iterate over the machines list and pull files from /.machines/${name} subdirectory. This allows me to have configuration that has machine specific configuration limited to those files while also keeping a modular reusable base. We also add a devshell that makes editing this repository easier in emacs.

  outputs = {
    nixpkgs,
    home-manager,
    emacs-overlay,
   # sops-nix,
    catppuccin,
    ...
  }:
    let
      user = import ./user.nix;
      lib = nixpkgs.lib;
      machines = [
        "traveldroid"
      ];
      pkgs = import nixpkgs {
        inherit (user) system;
      };
    in
      {
        nixosConfigurations = builtins.listToAttrs (
          builtins.map (machine: {
            name = machine;
            value = lib.nixosSystem {
              modules = [
                <<flake-emacs-module>>
                <<flake-config-module>>
                <<flake-home-module>>
                #sops-nix.nixosModules.sops           # sops
                catppuccin.nixosModules.catppuccin   # theme
              ];
              specialArgs = {
                hostname = machine;
                inherit user;
              };
            };
          }) machines
        );
        devShells.${user.system}.default = pkgs.mkShell {
          buildInputs = with pkgs; [
            nil               # nix lsp server
            nixfmt-rfc-style  # nix formatter
            #sops              # used to edit secrets
          ];
        };
      };

Lets look at the individual modules

  1. Emacs The first is the emacs overlay so that it uses the nix-community emacs overlay from the inputs instead of the nixpkgs one. Overlays are a special nix way to override existing packages within a repository.

      ({ ... }: {
        nixpkgs.overlays = [ emacs-overlay.overlays.default ];
      })
  2. Then the machine specific configuration, in this case, just "traveldroid".

      ./machines/${machine}/configuration.nix
  3. And finally the home-manager module. This can be initialized and managed on its own but I'd rather use the nixos-rebuild command to build everything instead of managing userland dotfiles separately.

      home-manager.nixosModules.home-manager
      {
        home-manager.useGlobalPkgs = true;
        home-manager.useUserPackages = true;
        home-manager.extraSpecialArgs = {
          inherit user;
        };
        <<flake-home-backup>>
        <<flake-home-config>>
      }
    • Home-Manager will not overwrite existing configuration files and that is good in most cases, but when everything is declarative like it is here, I'd rather that home-manager create a .backup and replace the file.

        home-manager.backupFileExtension = "backup";
    • Finally I pull in the machine specific home configuration. Along with the overrides from catppuccin.

        home-manager.users.${user.username} = {
          imports =  [
            ./machines/${machine}/home.nix
            catppuccin.homeModules.catppuccin
          ];
        };

Envrc + Direnv

Editing this file will be much nicer if we have the dev environment configured. That is done in the devshells section. But to auto load this dev shell, we need a .envrc file. This tells direnv to load the devshell in the flake. #Finally, we also look for a .envrc-private file and try to load that. That contains devshell specific secrets.

  use flake

  watch_file .envrc.private
  if [[ -f .envrc.private ]]; then
    source_env .envrc.private

Machines

The individual machines subdirectory is configured as follows :-

  +--machine
  |  +--configuration.nix
  |  +--home.nix
  |  +--hardware-configuration.nix
  • configuration.nix has the system configuration.
  • home.nix has the user level configuration.
  • hardware-configuration.nix has the unique hardware configuration.

nixos-rebuild switch --flake .#traveldroid looks for the traveldroid configuration (in /machines/traveldroid) and returns the configuration that is specific to that computer.

  • Note about imports imports = [] in a nix file will pull in the function/object from the list of files provided. This imported object (or function result) is just trivially merged into a common object.

We can take a look at that the common hardware options I have for all my machines.

Other Utils

Updates

To update the computer, I just need to update the flake.lock file to have references to the latest repository. This is done with :-

  nix flake update
Editing secrets

The age key needs to exist. Then I can edit the secrets using :-

  #sops edit secrets/secrets.yaml

Hardware

I'll let the code comments explain the file here.

  { pkgs, lib, user, config, ...} :
  {
    nixpkgs.hostPlatform = lib.mkDefault user.system;            # x86_64-linux
    powerManagement.cpuFreqGovernor = lib.mkDefault "powersave"; # enable power saving on the cpu

    # update cpu microcode with firmware that allows redistribution
    hardware.cpu.intel.updateMicrocode = lib.mkDefault config.hardware.enableRedistributableFirmware;

    hardware = {
      # always enable bluetooth
      bluetooth.enable = true;

      # always enable graphics drivers and enable a bunch of layers for it (including vulkan validation)
      graphics = {
        enable = true;
        extraPackages = with pkgs; [
          vulkan-validation-layers # helps catch and debug vulkan crashes
        ];
      };
    };

    hardware.enableAllFirmware = true; # enable all firmware regardless of license

Configuration

This section describes the main system configuration for the computers that I have. Nix will look for a default.nix file if you give it a path to a folder to import. And default.nix looks as follows :-

  { pkgs, user, ... } :
  {
    imports = [
      ./boot.nix
      ./login.nix
      ./cli.nix
      ./files.nix
      ./locale.nix
      ./nix-settings.nix
      ./networking.nix
      ./hyprland.nix
      ./services.nix
      ./audio.nix
      #./steam.nix
      #./sops.nix
      ./packages.nix
      ./flatpak.nix
    ];

    <<config-system-packages>>

    <<config-user>>

    <<config-programs>>

    <<config-fonts>>

    # enable the catppuccin theme for everything with mocha + blue accents
    catppuccin.enable = true;
    catppuccin.flavor = "mocha";
    catppuccin.accent = "blue";

    system.stateVersion = user.stateVersion;
  }

Whoa. Thats a lot of imports. Lets go through them one by one.

Nix Settings

These are global nix settings that configure the settings for the actual tool.

Boot

This file has most of the settings the control how the computer boots up.

  { pkgs, ... } :
  {
    boot = {
      initrd = {
        verbose = false;     # its a lot of logs. dont need it, unless we do.
        kernelModules = [ ]; # no kernel modules on boot
      };

      extraModulePackages = [ ];                   # no extra packages on boot either
      kernelPackages = pkgs.linuxPackages_latest;  # latest greatest linux kernel
      kernelParams = [ "silent" ];                 # quiet those logs

      consoleLogLevel = 0;                         # quiten more logs
      plymouth.enable = true;                      # graphical boot animation instead

      supportedFilesystems = [ "ntfs" ];           # should see the ntfs (windows)

        timeout = 5;                               # grub timeout to make a selection
      };
    };
  }

Login

Here we control what the login screen would look like. I'm using greetd's tuigreet for the ui. Doesn't match the rest of the aesthetic of the system (with hyprland), but I like its simplicity.

  { pkgs, user, ... } :
  {
    environment.systemPackages = with pkgs; [
      tuigreet
    ];

    services.greetd = {
      enable = true;
      settings = {
        default_session = {
          command = pkgs.lib.mkForce "${pkgs.tuigreet}/bin/tuigreet --remember --time --time-format '%I:%M %p | %a • %h | %F'";
        };
      };
    };
  }

CLI

This is the initial system level configuration for the terminal that I use on this machine. Its just zsh.

  { pkgs, user, ... }:
  {
    console.useXkbConfig = true;
    users.users.${user.username}.shell = pkgs.zsh;

    environment.shells = with pkgs; [ zsh ];
    programs.zsh.enable = true;
    environment.pathsToLink = [ "/share/zsh" ];
  }

Files

I use Thunar as the file explorer. Also setup a few plugins for Thunar in this config. Along with that, a few other utilities like zip and enabling services to automount usb drives.

  { pkgs, user, config, ... } :
  {
    environment.systemPackages = with pkgs; [
      zip
      unzip
      p7zip
      usbutils
      udiskie
    ];

    programs.thunar = {
      enable = true;
      plugins = with pkgs.xfce; [
        thunar-archive-plugin
        thunar-media-tags-plugin
        thunar-volman
      ];
    };

    programs.file-roller.enable = true; # thunar zip support
    programs.xfconf.enable = true; # to save thunar settings

    services = {
      gvfs.enable = true;    # Mount, trash, and other functionalities
      tumbler.enable = true; # Thumbnail support for images
      udisks2.enable = true; # Auto mount usb drives
    };
  }

Locale

I live in Netherlands and would like all my locale and timezone settings to match. Except my default locale.

  { user, ... } :
  let
    locale = user.locale;
    defaultLocale = "nl_NL.UTF-8";
  in
  {
    # Set your time zone.
    time.timeZone = "Europe/Amsterdam";

    # Select internationalisation properties.
    i18n.defaultLocale = defaultLocale;

    i18n.extraLocaleSettings = {
      LC_ADDRESS = locale;
      LC_IDENTIFICATION = locale;
      LC_MEASUREMENT = locale;
      LC_MONETARY = locale;
      LC_NAME = locale;
      LC_NUMERIC = locale;
      LC_PAPER = locale;
      LC_TELEPHONE = locale;
      LC_TIME = defaultLocale;
    };
  }

Networking

Not much to see here. I want networking to be enabled. I want firewall as well.

  { pkgs, ... } : {
    networking = {
      # allow automatic ip assignment when connecting to a network
      useDHCP = pkgs.lib.mkDefault true;
      networkmanager.enable = true;
      firewall.enable = true;

      # let wifi info be NOT declarative, allowing user to configure wifi.
      wireless.userControlled.enable = true;
      wireless.iwd.enable = true;
      networkmanager.wifi.backend = "wpa_supplicant";
    };

    # tui to manage wifi networks
    environment.systemPackages = with pkgs; [ impala ];
  }

Hyprland

This is a big one because the DE needs so much configuration. This section mostly installs Hyprland. The configuration is done in the home manager section.

  { pkgs, ... }:
  {
    nix.settings = {
      # add the hyprland cache so that we dont build hyprland from source
      substituters = [ "https://hyprland.cachix.org" ];
      trusted-public-keys = [
        "hyprland.cachix.org-1:a7pgxzMz7+chwVL3/pzj6jIBMioiJM7ypFP8PwtkuGc="
      ];
    };

    # these extra portals allow for things like screen sharing
    xdg = {
      portal = {
        enable = true;
        extraPortals = [
          pkgs.xdg-desktop-portal-wlr
          pkgs.xdg-desktop-portal-gtk
        ];
      };
    };

    environment.systemPackages = with pkgs; [

      hyprland-qtutils    # needed by hyprland
      hyprpolkitagent     # polkit agent
      grimblast           # screenshot

    # we use uwsm to manage launching hyprland
    # uswm will add hyprland to the login sessions with tuigreet.
    programs = {
      uwsm.enable = true;
      uwsm.waylandCompositors = {
        hyprland = {
          prettyName = "Hyprland";
          comment = "Hyprland compositor managed by UWSM";
          binPath = "/run/current-system/sw/bin/Hyprland";
        };
      };

      hyprland = {
        withUWSM  = true;
        enable = true;
        xwayland.enable = true;
      };
    };

    # this is mainly for the lock screen
    # lock.png is provided elsewhere
    services.xserver = {
      enable = true;

      desktopManager = {
        xterm.enable = false;
      };


      displayManager = {
        lightdm.background = ./lock.png;
      };
    };

    # this is a lot of env vars.
    # and this requires some cleanup
    # but hyprland moves fast and some of these are probably outdated already
    environment.sessionVariables = {
      XDG_SESSION_TYPE="wayland";
      XDG_CURRENT_DESKTOP="Hyprland";
      XDG_SESSION_DESKTOP="Hyprland";
      NIXOS_OZONE_WL="1";
      XCURSOR_SIZE="24";
    };

    # allow hyprlock (lockscreen) to lock user session
    security.pam.services.hyprlock = { };
    security.polkit.enable = true;
    security.pam.services.gdm.enableGnomeKeyring = true;
  }

Services

These are some of the services that I enable at the system level. Explanation in the comments.

  { user, ...} :
  {
    services = {
      blueman.enable = true;                # bluetooth manager
      fwupd.enable = true;                  # firmware updating service
      fstrim.enable = true;                 # ssd maintenance service
      thermald.enable = true;               # thermal regulation service
      printing.enable = true;               # printing services, cups
      gnome.gnome-keyring.enable = true;    # keyring
      flatpak.enable = true;                # allow installing things from flatpaks
      #flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

      # printer discovery
      avahi = {
        enable = true;
        nssmdns4 = true;
        openFirewall = true;
      };
    };

    virtualisation.docker.enable = true;    # enable docker
    users.users.${user.username}.extraGroups = [ "docker" ]; # add self to docker user group
  }

Audio

This is still a work in progress, but it almost works. I enable all the audio related services, hoping everything is going to be okay.

  { pkgs, ...}:
  {
    environment.systemPackages = with pkgs; [ pamixer ];
    services.pipewire = {
      enable = true;
      alsa.enable = true;
      alsa.support32Bit = true;
      pulse.enable = true;
      jack.enable = true;
    };

    # pipewire needs realtime scheduling access
    security.rtkit.enable = true;
  }

Sops

#We use sops to manage secrets on this machine.

#  { user, ...} :
#  {
#    sops.defaultSopsFile = ../secrets/secrets.yaml;
#    sops.defaultSopsFormat = "yaml";
#    sops.age.keyFile = "/home/${user.username}/.config/sops/age/keys.txt";
#
#    sops.secrets.claude_key = { # anthropic claude api key, used in emacs
#      owner = "${user.username}";
#    };
#  }

#Sops requires a public .sops.yaml that dictates how the secrets are encrypted. #This contains the public key and path to the secrets file.

#keys:
#  - &primary age1yq35g6mmlem0rhr47u6ewh8dctlwp9hj0s0ac60e4hrw9hjzlqms6crf7n
#creation_rules:
#  - path_regex: secrets/secrets.yaml$
#    key_groups:
#      - age:
#        - *primary

Miscellaneous Packages and Programs

  environment.systemPackages = with pkgs; [
    wget       # fetch utility
    curl       # more fetch utility
    binutils   # executable utilities, like ld
    dmidecode  # tool for dumping system info

      enable = true;
      enableSSHSupport = true;
    };
    firefox.enable = true;   # browser
    wireshark.enable = true; # vpn
  };

Fonts

Nothing much to see here. I love Aporetic, and I use it everywhere.

  fonts.packages = with pkgs; [
    aporetic
    nerd-fonts.iosevka
  ];

User Config

This creates the user profile that I login with. Initially created during install.

  users.users.${user.username} = {
    isNormalUser = true;
    description = "henrov";
    extraGroups = [
      "networkmanager" # allow editing network connections
      "wheel"          # can do sudo
      "scanner"        # access to the network scanner
      "lp"             # access to the printer
    ];
  };

Home

I use home-manager to manage my user level dotfiles and configurations. Most of the "theme" of the system is decided here. I also use it to install programs that are okay with being installed at the user level instead of the system.

  { pkgs, user, ... } :
  {
    imports = [
      ./waybar.nix
      ./wallpaper.nix
      ./lock.nix
      ./unity.nix
      ./hyprland.nix
      ./walker.nix
      ./theme.nix
      ./terminal.nix
      ./dev.nix
      ./emacs
    ];

    <<home-user>>

    <<home-packages>>

    programs.home-manager.enable =  true;
  }

Oof! Again with all the imports! We can go through them one at a time!

Wallpaper

./assets/background.png I use hyprpaper for setting the wallpaper. The image is copied into the home folder when applying this configuration and the tool picks it from there.

  { pkgs, ... }:
  {
    home.packages = with pkgs; [
      hyprpaper
    ];

    services.hyprpaper.enable = true;
    services.hyprpaper.settings = {
      ipc = "on";
      splash = false;
      splash_offset = 2.0;

      preload = [ "~/.background-image.png" ];
      wallpaper = [ ",~/.background-image.png" ];
    };

    home.file = {
      background = {
        source = ../assets/background.png;
        target = ".background-image.png";
      };
    };
  }

Lock Screen

The lock screen configured using hyprlock. I use hypridle to detect idle time and use wlogout to show a logout menu. They are configured below.

  { pkgs, ... } :
  {
    home.packages = with pkgs; [
      hyprlock
      hypridle
      wlogout
    ];


    home.file = {
      lock = {
        source = ../assets/lock.png;
        target = ".lock.png";
      };
    };

    services = {
      # hypridle to
      # 150 seconds - turn of monitor

        settings = {
          general = {
            lock_cmd = "pidof hyprlock || hyprlock";       # avoid starting multiple hyprlock instances.
            before_sleep_cmd = "loginctl lock-session";    # lock before suspend.
            after_sleep_cmd = "hyprctl dispatch dpms on";  # to avoid having to press a key twice to turn on the display.
          };

          listener = [
            {
              timeout = 150;                                # 2.5min.
              on-timeout = "brightnessctl -s set 10";         # set monitor backlight to minimum, avoid 0 on OLED monitor.
              on-resume = "brightnessctl -r";                 # monitor backlight restore.
            }
            {

            }
            {
              timeout = 1800;                                # 30min

Unity

I work with the Unity Game Engine and I have the unity hub installed globally, instead of in a project flake. Often I work with dotnet directly inside of unity and so we set that up too.

  { pkgs, ... }:

       (pkgs.unityhub.override {
         extraPkgs = pkgs: with pkgs; [

Walker

This is how I launch applications. It is bound to Win+Space in the hyprland config above.

  {
    services.walker.enable = true;
    services.walker.settings = {
      close = "ctrl g";
      next = "ctrl n";
      previous = "ctrl p";
      quick_activate = ["1" "2" "3" "4"];
    };
  }

Theme

I use the Catppuccin almost everywhere. The nix module integrates almost automatically everywhere (except gtk). You'll notice the color values in multiple places outside this as well.

  { pkgs, ...}:
  {
    gtk = {
      enable = true;
      colorScheme = "dark";
      theme = {
        name = "Catppuccin-GTK-Grey-Dark-Compact";
        package = (pkgs.magnetic-catppuccin-gtk.override {
          accent = [ "grey" ];
          shade = "dark";
          tweaks = [ "black" ];
          size = "compact";
        });
      };

      iconTheme.name = "Papirus-Dark";
    };

    catppuccin.enable = true;
    catppuccin.flavor = "mocha";
    catppuccin.accent = "blue";
    catppuccin.gtk.icon.enable = true;
    catppuccin.cursors.enable = true;
  }

Terminal

Alacritty is my terminal program. The snippet below configures how it looks.

  {
    programs = {
     # <henrov: I need to setup kitty here>
      alacritty = {
        enable = true;
        settings = {
          font.normal.family = "Aporetic Sans Mono";
          font.size = 12;
          terminal.shell.program = "zsh";

          window = {
            padding.x = 4;
            padding.y = 4;
          };
        };
      };
    };

    catppuccin.alacritty.enable = true;
    catppuccin.alacritty.flavor = "mocha";
  }

Dev Tools

All the miscellaneous dev tools on this computer.

Emacs

I practically live inside emacs. The configuration for it is a mix between init.el and the nix configuration. Nix allows me to install emacs packages as part of the configuration which is most of the following file. I install the nix community provided emacs overlay that lets me have the latest emacs with pgtk ui (for wayland). Comments describe the emacs package and what it does.

Machines

Only a few more things left. Specifically the machine level extra settings.

Smallbox

The configuration for the laptop does not change much. Most changes are because the hardware is different.

System Level

Nothing specific for the laptop.

  { user, ... } : {
    imports =
      [
        ./hardware-configuration.nix
        ../../configuration
      ];

    <<traveldroid-secrets>>
  }

Hardware

This is the most different. Mostly taken from hardware-configuration.nix setup at first install.

  {
    hostname,
    pkgs,
    lib,
    modulesPath,
    user,
    config,
    ...
  }:
  {
    imports = [
      (modulesPath + "/installer/scan/not-detected.nix")
      ../../hardware/hardware.nix
    ];

  boot.initrd.availableKernelModules = [ "xhci_pci" "nvme" "usb_storage" "sd_mod" "rtsx_usb_sdmmc" ];
  boot.initrd.kernelModules = [ ];
  boot.kernelModules = [ "kvm-intel" ];
  boot.extraModulePackages = [ ];

  fileSystems."/" =
    { device = "/dev/disk/by-uuid/69433a14-fbaf-401b-af85-cd1bbf02b4e2";
      fsType = "ext4";
    };

  fileSystems."/boot" =
    { device = "/dev/disk/by-uuid/811D-0676";
      fsType = "vfat";
      options = [ "fmask=0077" "dmask=0077" ];
    };

  swapDevices =
    [ { device = "/dev/disk/by-uuid/b6c557c2-7682-460b-a5e7-8f6f2f429a3a"; }
    ];

  nixpkgs.hostPlatform = lib.mkDefault "x86_64-linux";
  hardware.cpu.intel.updateMicrocode = lib.mkDefault config.hardware.enableRedistributableFirmware;
  }

Home

This is mostly about configuring the monitor and key bindings. And laptop specific utilities.

  { pkgs, ... } : {
    imports = [
      ../../home
    ];

    home.packages = with pkgs; [
      brightnessctl
    ];

    wayland.windowManager.hyprland.settings = {
      bind = [
        "XF86MonBrightnessUp, exec, brightnessctl set 5%+"
        "XF86MonBrightnessDown, exec, brightnessctl set 5%-"
        "XF86AudioRaiseVolume, exec, wpctl set-volume @DEFAULT_AUDIO_SINK@ 5%+"
        "XF86AudioLowerVolume, exec, wpctl set-volume @DEFAULT_AUDIO_SINK@ 5%-"
        "XF86AudioMute, exec, wpctl set-mute @DEFAULT_AUDIO_SINK@ toggle"
        "XF86AudioMicMute, exec, wpctl set-mute @DEFAULT_AUDIO_SOURCE@ toggle"
      ];

      bindl = [
        '', switch:on:Lid Switch, exec, hyprctl keyword monitor "eDP-1, disable"''
        '', switch:off:Lid Switch, exec, hyprctl keyword monitor "eDP-1, preferred, 0x0, 1"''
      ];
    };
  }
