LabWC is a stacking Wayland compositor. Although it wasn't intended like that, it can serve as a drop-in replacement for the Openbox window manager (the same way Sway is for I3wm).

This wiki was written starting from a fresh install using the "Alpine 3.16 x86 extended .iso". The steps begin from the first reboot after running setup-alpine and performing a sys install to disk.

Many steps below were taken from the wiki entry for installing Sway, as both are wlroots-based Wayland compositors. Another interesting page, because of the same reasons, is the River compositor's.

Prerequisites

Note: These steps posted as both Sway and LabWC prerequisites could be applied to almost all wlroots-based Wayland compositors.

First, install & configure eudev:

# apk add eudev
# setup-udev

Then install graphics drivers appropriate to your system:

# apk add mesa-dri-gallium  # gallium
# apk add mesa-dri-classic  # or classic
# apk add mesa-dri-nouveau  # for nvidia users

The following links contain guides for setting up the video stack.

Add yourself to the input and video groups:

# adduser $USER input
# adduser $USER video

You have to log out and back in for this to take effect.

Install some TTF fonts:

# apk add ttf-dejavu

Since wlroots 0.14, you need to set up libseat backend if you wish to run labwc directly (without nesting it in another wayland compositor). To do that, enable the community repository and choose one of the following methods:

Option 1: seatd daemon (recommended)
# apk add seatd
# rc-update add seatd
# rc-service seatd start
# adduser $USER seat

If you are already logged in as a $USER, you will need to relogin.

Option 2: seatd-launch
# apk add seatd-launch

When starting labwc, you will need to prefix invocation with seatd-launch. Note: seatd-launch is a suid binary, so it might be wise to use one of the other methods from a security perspective.

Option 3: elogind daemon
# apk add elogind polkit-elogind
# rc-update add elogind
# rc-service elogind start

Using elogind will automatically set the necessary permissions, so you can skip adding groups like seat and video

Installation

We can now install labwc:

# apk add labwc labwc-doc
# apk add                \ # Install optional dependencies:
    xwayland             \ # recommended for compatibility reasons
    foot                 \ # default terminal emulator
    rofi                 \ # default application launcher (dmenu could be used instead)
    swaylock             \ # lockscreen tool
    swayidle               # idle management (DPMS) daemon

Note that almost all optional dependencies are the same than Sway's. Another interesting packages are specified into the project's README, as it can be waybar (included into the Alpine's repository) as navigation bar.

Running LabWC

To run labwc, first set XDG_RUNTIME_DIR to a suitable location (e.g. create a .run folder in your home directory and set it to ~/.run). Then run labwc from the Linux console (dbus-launch is used because pipewire needs it, it is included in dbus-x11 and you may omit it):

$ XDG_RUNTIME_DIR=~/.run dbus-launch labwc

(if you run labwc with seatd-launch, you will need to use $ XDG_RUNTIME_DIR=~/.run dbus-launch seatd-launch labwc)

You can also create a simple alias in your shell rc file (e.g. .zshrc), like:

alias labwcinit="XDG_RUNTIME_DIR=~/.run dbus-launch seatd-launch labwc"

See the Wayland page for a permanent configuration (recommended).

Note:

swaylock needs to be able to read your /etc/shadow file to be able to validate your password

Configuration and Usage

LabWC aims to implement the [openbox.org/wiki/Help:Contents openbox 3.4] specification, so many things working in OpenBox should be compatible.

Moreover, the project provides examples for all the configuration files and some themes, explaining where it must be located each one of them.

For additional information, labwc manpages and wiki can be consulted.
