Lumen

Lumen

A Wayland desktop shell with the bar, notifications, OSD, wallpaper, and device controls built in. Written in Rust with GTK4 and Relm4.

Lumen is arranged as a single Rust workspace. The service crates live locally under crates/, so app and service changes can be developed from one checkout.

Configure it in config.toml, through the lumen-settings GUI, or with the lumen config CLI.

Lumen settings GUI

Documentation

Full guides, reference, and walkthroughs are at lumen.cybex.net.

Install

Lumen isn't packaged for any distro yet, so install it from source. Native packages (AUR and others) are planned.

First install the system dependencies for your distro:

Arch

Install Rust via rustup, then the system libraries:

sudo pacman -S --needed git gtk4 gtk4-layer-shell gtksourceview5 \
libpulse fftw libpipewire systemd-libs clang base-devel

Runtime daemons for the battery, bluetooth, network, power, and audio modules (skip any you don't need):

sudo pacman -S --needed bluez bluez-utils networkmanager upower \
power-profiles-daemon pipewire wireplumber pipewire-pulse
sudo systemctl enable --now bluetooth NetworkManager upower power-profiles-daemon
Debian / Ubuntu

Ubuntu 24.04 LTS does not package libgtk4-layer-shell-dev. Use Ubuntu 25.04+ or Debian 13 (trixie).

Install Rust via rustup, then the system libraries:

sudo apt install git pkg-config cmake libgtk-4-dev libgtk4-layer-shell-dev \
libgtksourceview-5-dev libpulse-dev libfftw3-dev libpipewire-0.3-dev \
libudev-dev clang build-essential

Runtime daemons:

sudo apt install dbus-user-session bluez network-manager \
upower power-profiles-daemon pipewire-pulse wireplumber
sudo systemctl enable --now bluetooth NetworkManager upower power-profiles-daemon
Fedora

Requires Fedora 42 or later.

Install Rust via rustup, then the system libraries:

sudo dnf install git cmake pkgconf-pkg-config gtk4-devel gtk4-layer-shell-devel \
gtksourceview5-devel pulseaudio-libs-devel fftw-devel pipewire-devel \
systemd-devel clang gcc

Fedora Workstation already ships the runtime daemons. Minimal and Server installs need:

sudo dnf install pipewire-pulseaudio wireplumber NetworkManager bluez upower \
power-profiles-daemon
sudo systemctl enable --now bluetooth NetworkManager upower power-profiles-daemon

Build and launch:

git clone https://github.com/DigitalPals/Lumen.git Lumen
cd Lumen
cargo install --path lumen
cargo install --path crates/lumen-settings
lumen icons setup
lumen panel start

On a different distro? See lumen.cybex.net/guide/getting-started for the library-version reference.

Configuration

The config file is at ~/.config/lumen/config.toml. Changes reload on save:

[bar]
location = "top"scale = 1.25
[[bar.layout]]
monitor = "*"left = ["dashboard"]
center = ["clock"]
right = ["volume", "network", "bluetooth", "battery"]
[modules.clock]
format = "%H:%M"

Every field is documented at lumen.cybex.net/config.

Requirements

A Wayland compositor that implements the wlr-layer-shell protocol. Compositor-specific modules currently target Hyprland, Niri and Mango; Sway support is planned.

Lumen
Lumen
A Wayland desktop shell with the bar, notifications, OSD, wallpaper, and device controls built in. Written in Rust with GTK4 and Relm4.
Lumen is arranged as a single Rust workspace. The service crates live locally under crates/, so app and service changes can be developed from one checkout.
Configure it in config.toml, through the lumen-settings GUI, or with the lumen config CLI.
Lumen desktop shell
Lumen settings GUI
Documentation
Full guides, reference, and walkthroughs are at lumen.cybex.net.
Install
Lumen isn't packaged for any distro yet, so install it from source. Native packages (AUR and others) are planned.
First install the system dependencies for your distro:
Arch
Install Rust via rustup, then the system libraries:
sudo pacman -S --needed git gtk4 gtk4-layer-shell gtksourceview5 \
libpulse fftw libpipewire systemd-libs clang base-devel
Runtime daemons for the battery, bluetooth, network, power, and audio modules (skip any you don't need):
sudo pacman -S --needed bluez bluez-utils networkmanager upower \
power-profiles-daemon pipewire wireplumber pipewire-pulse
sudo systemctl enable --now bluetooth NetworkManager upower power-profiles-daemon
Debian / Ubuntu
Ubuntu 24.04 LTS does not package libgtk4-layer-shell-dev. Use Ubuntu 25.04+ or Debian 13 (trixie).
Install Rust via rustup, then the system libraries:
sudo apt install git pkg-config cmake libgtk-4-dev libgtk4-layer-shell-dev \
libgtksourceview-5-dev libpulse-dev libfftw3-dev libpipewire-0.3-dev \
libudev-dev clang build-essential
Runtime daemons:
sudo apt install dbus-user-session bluez network-manager \
upower power-profiles-daemon pipewire-pulse wireplumber
sudo systemctl enable --now bluetooth NetworkManager upower power-profiles-daemon
Fedora
Requires Fedora 42 or later.
Install Rust via rustup, then the system libraries:
sudo dnf install git cmake pkgconf-pkg-config gtk4-devel gtk4-layer-shell-devel \
gtksourceview5-devel pulseaudio-libs-devel fftw-devel pipewire-devel \
systemd-devel clang gcc
Fedora Workstation already ships the runtime daemons. Minimal and Server installs need:
sudo dnf install pipewire-pulseaudio wireplumber NetworkManager bluez upower \
power-profiles-daemon
sudo systemctl enable --now bluetooth NetworkManager upower power-profiles-daemon
Build and launch:
git clone https://github.com/DigitalPals/Lumen.git Lumen
cd Lumen
cargo install --path lumen
cargo install --path crates/lumen-settings
lumen icons setup
lumen panel start
On a different distro? See lumen.cybex.net/guide/getting-started for the library-version reference.
Configuration
The config file is at ~/.config/lumen/config.toml. Changes reload on save:
[bar]
location = "top"scale = 1.25
[[bar.layout]]
monitor = "*"left = ["dashboard"]
center = ["clock"]
right = ["volume", "network", "bluetooth", "battery"]
[modules.clock]
format = "%H:%M"
