Nomarchy/docs/OPTIONS.md

Nomarchy Options Reference

Every option Nomarchy exposes for downstream flakes. Paths under nomarchy.system.* are NixOS options (set in system.nix); paths under nomarchy.* (no system segment) are Home Manager options (set in home.nix). nomarchy.hardware.* is NixOS.

The installer-generated configuration writes a few of these for you (timezone, formFactor, hardware vendor flags, keymap, locale). Anything not listed there is opt-in — set it yourself.

To see the live default for any option:

nix eval .#nixosConfigurations.<host>.config.nomarchy.system.<path>
nix eval .#homeConfigurations.<user>.config.nomarchy.<path>

---

NixOS options (system.nix)

nomarchy.system.dns

DNS provider. One of "DHCP" (default), "Cloudflare", "Google", "Custom". With "Custom", set nomarchy.system.customDns to a list of nameservers. Anything other than "DHCP" also enables services.resolved with DNSSEC and DNS-over-TLS.

Defined in core/system/options.nix; wired in core/system/network.nix.

nomarchy.system.customDns

listOf str, default []. Nameservers used when dns = "Custom".

nomarchy.system.wifi.powersave

bool, default true. Sets networking.networkmanager.wifi.powersave. Turn off if you see drops on idle Wi-Fi.

nomarchy.system.timezone

str, default "UTC". The installer writes time.timeZone directly, so this option is informational unless you wire it into your own modules.

nomarchy.system.formFactor

enum [ "laptop" "desktop" ], default "laptop". Drives UI affordances and the laptop power preset. The installer auto-detects via /sys/class/power_supply/BAT*. The default is "laptop" because the battery widget renders empty when no battery is present — safe on a desktop, useful on a laptop.

Wired in features/desktop/waybar/default.nix (filters the battery widget out on desktop), features/scripts/battery-monitor.nix (skips the timer on desktop), and nomarchy.system.laptop.enable (defaults true when this is "laptop").

nomarchy.system.theme

str, default "summer-night". Theme name. Mirror of the home-side nomarchy.theme. Set both if you also want NixOS-side modules (e.g. SDDM theming) to follow.

nomarchy.system.features.fingerprint

bool, default false. Enables services.fprintd.enable.

nomarchy.system.features.fido2

bool, default false. Enables security.pam.u2f (sufficient, with cue).

nomarchy.system.features.hybridGPU

bool, default false. NVIDIA-hybrid laptop support. Wires:

• services.supergfxd.enable for runtime mode switching (Integrated / Hybrid / Vfio / AsusEgpu), driven by nomarchy-toggle-hybrid-gpu.
• The NVIDIA driver stack (services.xserver.videoDrivers = ["nvidia"], hardware.graphics.{enable,enable32Bit}, hardware.nvidia.{modesetting,powerManagement}.enable, boot.kernelParams = ["nvidia-drm.modeset=1"]).

All driver knobs use lib.mkDefault, so a downstream system.nix can pin a beta driver or flip to the open kernel module without forking the module.

You still have to add bus IDs — they're per-machine and can't be derived from any flag. Find them with lspci -D | grep -E 'VGA|3D', then in your /etc/nixos/system.nix:

hardware.nvidia.prime = {
  offload.enable = true;
  offload.enableOffloadCmd = true;
  intelBusId  = "PCI:0:2:0";   # or `amdgpuBusId` for AMD iGPU
  nvidiaBusId = "PCI:1:0:0";
};

Without prime config, supergfxd still switches modes but render-offload via nvidia-offload <cmd> is unavailable.

nomarchy.system.snapper.enable

bool, default false. BTRFS timeline snapshots of /. Auto-disables when / isn't BTRFS. Includes a nixos-rebuild-snap wrapper that takes a "Pre-rebuild" snapshot before each switch.

nomarchy.system.hibernation.enable

bool, default false. Suspend-then-hibernate on lid close, idle, and power button. Requires a disk swap device or swapfile sized to at least RAM — zRAM alone is not enough.

nomarchy.system.hibernation.idleMinutes

int, default 30. Idle minutes before suspend-then-hibernate fires.

nomarchy.system.laptop.enable

bool, default nomarchy.system.formFactor == "laptop". Laptop power preset: TLP (with sane AC/battery governors and ThinkPad-style 75/80 charge thresholds), services.upower, services.thermald (gated by laptop.thermald), and a brightnessctl udev rule so the existing nomarchy-brightness-{display,keyboard} scripts run without root. Force-disables services.power-profiles-daemon (mutually exclusive with TLP) — to use PPD instead, set laptop.enable = false and wire it yourself. Lid-close action defers to nomarchy.system.hibernation.enable: suspend-then-hibernate when on, suspend otherwise. Charge thresholds are only honored on supported hardware (ThinkPad, some ASUS); harmless warning elsewhere.

nomarchy.system.laptop.thermald

bool, default true on x86_64. Enables services.thermald (Intel thermal daemon). Harmless no-op on AMD; gated off on aarch64.

nomarchy.system.desktop.enable

bool, default nomarchy.system.formFactor == "desktop". Desktop preset: pins powerManagement.cpuFreqGovernor to "performance" (via mkDefault) and enables services.zfs.autoScrub + services.zfs.trim so a future ZFS pool gets sensible maintenance without further config. The ZFS knobs are no-ops until you add boot.supportedFilesystems = [ "zfs" ] (plus networking.hostId) and a pool. Battery-widget filtering is handled by formFactor itself, so this preset doesn't repeat it.

nomarchy.system.accessibility.enable

bool, default false. Accessibility preset: enables services.gnome.at-spi2-core (AT-SPI2 framework), installs pkgs.orca (screen reader) into environment.systemPackages, and sets XCURSOR_SIZE to accessibility.cursorSize. Off by default — accessibility is a personal preference, not hardware-derived. The Hyprland-side bits (slower key-repeat, Orca launch keybinding, high-contrast palette) are a separate roadmap item.

nomarchy.system.accessibility.cursorSize

int, default 32. XCURSOR_SIZE when accessibility.enable = true. NixOS default is 24; 32 is a safer floor for low-vision users.

nomarchy.system.gaming.enable

bool, default false. Gaming preset: enables programs.steam (with remotePlay and localNetworkGameTransfers firewall holes opened by mkDefault), programs.gamemode (the launching user must be in the gamemode group), and services.flatpak. The flathub remote isn't added declaratively — after first boot, run flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo. Pair with the home-side companion nomarchy.gaming.enable for the Hyprland fullscreen-on-Steam-launch window rule.

nomarchy.system.containers.enable

bool, default false. Rootless Podman with Docker compatibility (docker → podman), plus podman-compose, podman-tui, and dive.

nomarchy.system.virtualization.libvirt.enable

bool, default false. libvirt daemon, virt-manager, and OVMF. Add your user to the libvirtd group.

nomarchy.system.virtualization.docker.enable

bool, default false. Docker daemon and docker-compose. Add your user to the docker group.

nomarchy.system.keyring.enable

bool, default true. Auto-unlock GNOME Keyring at login and route SSH keys through gcr-ssh-agent. On by default — near-universal QoL improvement.

nomarchy.system.inputMethod.enable

bool, default false. fcitx5 input method for CJK / IME. Wires NixOS's i18n.inputMethod and autostarts fcitx5-daemon.

nomarchy.system.voxtype.enable

bool, default false. voxtype voice-typing integration. voxtype isn't packaged in nixpkgs — when you enable this, install voxtype yourself (e.g. home.packages = [ (pkgs.callPackage … {}) ]). With this off the SUPER+CTRL+X keybinding and waybar widget are no-ops.

nomarchy.hardware.isXPS

bool, default false. Dell XPS fixes — haptic touchpad service and PCI/I²C power-control udev rules.

nomarchy.hardware.isT2Mac

bool, default false. Apple T2 MacBook fixes — IOMMU kernel params, apple-bce module, brcmfmac feature mask.

nomarchy.hardware.isFramework

bool, default false. Framework laptop QMK HID udev rule.

nomarchy.hardware.fwupd

bool, default false. Enables services.fwupd firmware update service.

nomarchy.hardware.hasIPU7Camera

bool, default false. Intel IPU7 camera support (kernel modules + firmware).

nomarchy.system.impermanence.enable

bool, default false. Erase Your Darlings root wipe on boot. Defined in core/system/impermanence.nix. The installer writes the flag based on the impermanence prompt.

nomarchy.system.impermanence.mainLuksName

str, default "crypted". Name of the /dev/mapper entry holding the BTRFS root. The disko layout uses "crypted" on single-disk installs and "crypted_main" once multiple drives are selected — the installer writes the matching value automatically.

nomarchy.system.impermanence.user

str, default "nomarchy". Primary user whose home subset (.ssh, .gnupg, .local/share/keyrings, Documents, Downloads, Pictures, Videos, Projects) survives the rootfs wipe. Must match the user created via users.users.<name> — otherwise the persistence block is silently inert and the user's home directory is wiped on every boot. The installer writes this for you.

---

Home Manager options (home.nix)

nomarchy.theme

str, default "summer-night". Active theme name. Available themes are the directories under themes/palettes/.

nomarchy.panelPosition

enum ["top", "bottom"], default "top". Waybar panel position.

nomarchy.formFactor

enum [ "laptop" "desktop" ], default "laptop". Mirror of nomarchy.system.formFactor. Filters laptop-only widgets out of waybar (battery) when set to "desktop". The installer writes both system and home values together.

nomarchy.wallpaper

str, default "". Absolute path to a wallpaper override. Empty string means "use the active theme's default wallpaper".

nomarchy.toggles.suspend

bool, default true. Whether suspend appears in the system menu.

nomarchy.toggles.screensaver

bool, default true. Whether the screensaver is enabled.

nomarchy.toggles.idle

bool, default true. Whether the idle lock is enabled (hypridle).

nomarchy.toggles.nightlight

bool, default false. Enables hyprsunset.

nomarchy.toggles.waybar

bool, default true. Whether the top bar is deployed at all.

nomarchy.toggles.skipVsCodeTheme

bool, default false. Skip theme overrides in VSCode — useful if you manage VSCode themes yourself.

nomarchy.nightlightTemperature

int, default 4000. Nightlight color temperature (Kelvin).

nomarchy.hyprland.gaps_in

int, default 5. Inner gaps.

nomarchy.hyprland.gaps_out

int, default 10. Outer gaps.

nomarchy.hyprland.border_size

int, default 2. Window border width.

nomarchy.fonts.monospace

str, default "JetBrainsMono Nerd Font". Used by terminals, VSCode, etc.

nomarchy.iconsTheme

str, default "Yaru-blue". GTK/Qt icon theme name.

nomarchy.isLightMode

bool, default false. Whether the active theme is a light theme. Affects nightlight defaults and a few app theme decisions.

nomarchy.cursor.name

str, default "Bibata-Modern-Ice". Cursor theme name.

nomarchy.cursor.package

package, default pkgs.bibata-cursors. Package providing the cursor theme. Override both name and package together if you switch themes.

nomarchy.configOverrides

nullOr path, default null. Path to a directory containing config overrides. See "Overrides" below.

nomarchy.behavior.hyprland.bindings

bool, default true. Deploy the default Hyprland keybindings. Set to false if you want to write bindings.conf from scratch.

nomarchy.behavior.hyprland.input

bool, default true. Deploy default input settings (kb_layout, mouse accel, etc).

nomarchy.behavior.hyprland.windowRules

bool, default true. Deploy default window rules.

nomarchy.behavior.hyprland.autostart

bool, default true. Deploy the default autostart.conf (hypridle, mako, swayosd, nm-applet, etc).

nomarchy.apps.opencode.enable

bool, default false. opencode AI coding CLI integration. Deploys ~/.config/opencode/opencode.json. The opencode package itself is not installed by Nomarchy — add it to your home.packages.

nomarchy.gaming.enable

bool, default false. Home-side companion to nomarchy.system.gaming.enable. Adds a Hyprland windowrulev2 = fullscreen, class:^(steam_app_).*$ so games launched through Steam grab the whole screen instead of opening windowed. Set to the same value as the system option; the installer flips both when the Gaming profile is selected.

nomarchy.vscode.devExtensions

bool, default false. Install Nomarchy's curated VSCode extension pack (Nix, language servers, theme variants).

nomarchy.themeLoader.enable

bool, default true. Auto-load theme-specific app configs (btop, waybar, mako, kitty, alacritty) from the active theme. Disable if you want to provide your own.

nomarchy.themeLoader.apps.{btop,waybar,mako,kitty,alacritty}

bool, default true each. Per-app toggles for the theme loader — pick which apps follow the active theme.

nomarchy.overrides.enable

bool, default true. Enable file-based overrides loaded from ~/.config/nomarchy/overrides/. With this on, Nomarchy looks for matching files in that directory and substitutes them for the bundled defaults.

nomarchy.overrides.paths

attrsOf path, default {}. Override paths discovered at build time. Populated by the override system — you don't normally set this directly.

Examples

Minimal system.nix for a desktop with Cloudflare DNS, Snapper, and rootless Podman

{
  nomarchy.system = {
    dns = "Cloudflare";
    formFactor = "desktop";
    snapper.enable = true;
    containers.enable = true;
  };
}

Minimal home.nix for a Tokyo-night user with custom gaps and opencode

{
  nomarchy = {
    theme = "tokyo-night";
    hyprland.gaps_in = 8;
    hyprland.gaps_out = 16;
    apps.opencode.enable = true;
  };
}

Disable Nomarchy's default Hyprland keybindings to ship your own

{
  nomarchy.behavior.hyprland.bindings = false;
}

Then put your own bindings.conf at ~/.config/nomarchy/overrides/hypr/bindings.conf (with nomarchy.overrides.enable = true;, which is the default).
