Moonarch

Reproducible Arch Linux desktop environment — fully automated from bare metal to a configured Niri (scrollable tiling Wayland) system with Catppuccin Mocha theming.

Moonarch combines archinstall for the base system with post-install automation that handles packages, XDG defaults, system services, greeter, idle management, and a Walker launcher with native providers and dmenu-based helper scripts. The result is a complete development/productivity desktop that can be rebuilt from scratch in minutes.

Why These Choices

Component	Choice	Why
Compositor	Niri	Scrollable tiling — no fixed grid, infinite horizontal workspace. Purpose-built Wayland compositor, not an X11 port.
Greeter	greetd + moongreet	Minimal, Wayland-native login. moongreet provides GTK4 UI with fingerprint support, running inside its own Niri instance.
Lock Screen	moonlock	ext-session-lock-v1 protocol — compositor guarantees lock on crash. PAM + fprintd, GPU blur, multi-monitor.
Power Menu	moonset	GTK4 Layer Shell overlay above Waybar. Lock, logout, hibernate, reboot, shutdown with confirmation.
Idle Manager	stasis	Separate AC/battery power plans. Brightness dimming, DPMS, lock (via moonlock), and suspend on configurable timeouts.
Bar	Waybar	Wayland-native, highly customizable. Niri workspace/window modules via community plugins.
Launcher	Walker + Elephant	Wayland-native GTK4 launcher with built-in providers for apps, clipboard, bluetooth, audio, files, and calculator. Dmenu mode for custom scripts (VPN, CPU governor).
Terminal	Foot	Fast, minimal Wayland-native terminal. Server mode for instant window spawning.
Shell	Zsh	Programmable completion, FZF integration, syntax highlighting.
Audio	PipeWire	Drop-in replacement for PulseAudio/JACK with lower latency. RNNoise input denoising configured out of the box.
Display Management	kanshi + wdisplays-persistent	kanshi auto-switches output profiles on hotplug. wdisplays-persistent saves changes directly to kanshi config.
Notifications	swaync	GTK4 notification daemon with DND toggle, grouping, MPRIS support. Fractional scaling via native GTK4.
Clipboard	cliphist + Walker	Clipboard history stored in runtime dir, wiped on session start. Walker provides the picker UI.
GTK Theme	Colloid-Grey-Dark-Catppuccin	Catppuccin Mocha palette, grey accent, explicit dark variant.
Icons	Colloid-Grey-Catppuccin-Dark	Catppuccin-colored icon set matching the GTK theme.
Cursor	Sweet-cursors	Visible on dark backgrounds without clashing.
Font	UbuntuSans Nerd Font	Clean sans-serif with full Nerd Font glyph coverage for bar/terminal icons.
Wallpaper	waypaper + awww	waypaper provides GUI selection, awww handles animated transitions (60 FPS, 2s crossfade).
Night Light	wlsunset	Wayland-native blue light filter via wlr-gamma-control. Toggleable from Waybar brightness group.
Firewall	UFW	Simple deny-incoming/allow-outgoing default. Sane baseline without iptables complexity.
AUR Helper	paru	Rust-based, pacman-compatible. Supports custom PKGBUILD repos for moongreet/moonlock/moonset.

Quick Start

Fresh Install (Bare Metal)

1. Boot the Arch ISO and download the config:

   curl -O https://gitea.moonarch.de/nevaforget/moonarch/raw/branch/main/config/user_configuration.json
   archinstall --config user_configuration.json
   

2. Choose disk and kernel interactively — everything else comes from the config.
3. Reboot, log in, then:

   /opt/moonarch/scripts/post-install.sh
   

4. Reboot again — done.

The archinstall config clones this repo to /opt/moonarch via custom-commands. post-install.sh handles the remaining ~95 packages, all configs, themes, services, and user setup.

Transform (Existing Arch+Wayland System)

Already running Arch with a Wayland compositor (Sway, Hyprland, GNOME Wayland, etc.)? Transform converts your system to Moonarch without reinstalling.

Prerequisites: Active Wayland session, git installed.

# Clone the repo
sudo git clone https://gitea.moonarch.de/nevaforget/moonarch.git /opt/moonarch

# Preview what will happen (no changes made)
/opt/moonarch/scripts/transform.sh --dry-run

# Run the transform
/opt/moonarch/scripts/transform.sh

# Reboot (do NOT log out — your previous DM is already disabled)
sudo reboot

The script will:

1. Show a pre-flight summary (package diff, config changes, detected conflicts)
2. Back up your ~/.config/, ~/.zshrc, and /etc/xdg/ to timestamped tar archives
3. Disable conflicting display managers (SDDM, GDM, LightDM, etc.)
4. Remove conflicting packages (e.g. PulseAudio → PipeWire)
5. Install all Moonarch packages and configs (hard overwrite of most user configs; kanshi display profiles are preserved)
6. Enable greetd, firewall, and system services

Update

moonarch-update

Interactive updater that upgrades system and AUR packages, reconciles package lists against what's installed, and cleans orphaned packages. Config deployment happens automatically via the moonarch-git package on paru -Syu.

Customization

All system configs live in /etc/xdg/ and can be overridden per-user in ~/.config/:

Component	System Default	User Override
Niri	/etc/xdg/niri/config.kdl	~/.config/niri/config.kdl
Waybar	/etc/xdg/waybar/	~/.config/waybar/
Walker	/etc/xdg/walker/	~/.config/walker/
Foot	/etc/xdg/foot/foot.ini	~/.config/foot/foot.ini
swaync	/etc/xdg/swaync/	~/.config/swaync/
kanshi	/etc/xdg/kanshi/config	~/.config/kanshi/config
PipeWire	/etc/xdg/pipewire/	~/.config/pipewire/
Zsh	/etc/zsh/zshrc.moonarch	~/.zshrc + ~/.zshrc.d/

Helper scripts in /usr/bin/moonarch-* are not meant to be overridden — they are part of the system and updated via paru -Syu.

System Services

Service	Purpose
greetd	Login greeter (runs moongreet inside Niri)
NetworkManager	Network management (WiFi, VPN, Ethernet)
bluetooth	Bluetooth stack (bluez)
systemd-timesyncd	NTP time synchronization
ufw	Firewall (deny incoming, allow outgoing)
auto-cpufreq	CPU frequency scaling (AC: performance, battery: powersave)

User Services (systemd --user)

Service	Purpose
cliphist	Clipboard history (wipes on session start, stores in runtime dir)
kanshi	Dynamic display configuration (auto-switch output profiles on hotplug)
nautilus	File manager preload (faster first launch)
stasis	Idle manager (dimming, DPMS, lock, suspend on AC/battery plans)
walker	Walker application launcher (GTK4 service mode for instant startup)

Moonarch Ecosystem

Moonarch is the deployment and configuration layer. Three companion projects provide the Wayland session UI — all built with Rust + gtk4-rs and sharing Catppuccin Mocha theming:

Project	Role	Installed via
moongreet	greetd greeter (GTK4 Layer Shell, fingerprint, i18n)	paru -S moongreet-git
moonlock	Wayland lock screen (ext-session-lock-v1, PAM, fprintd)	paru -S moonlock-git
moonset	Power menu overlay (GTK4 Layer Shell)	paru -S moonset-git

These are built from a custom paru package repository added during post-install.
