Labwc stands for Lab Wayland Compositor[1]. According to the official website:

  Labwc is a wlroots-based window-stacking compositor for wayland, inspired by openbox.
  It is light-weight and independent with a focus on simply stacking windows well and rendering some window decorations. It relies on clients for panels, screenshots, wallpapers and so on to create a full desktop environment.
  Labwc tries to stay in keeping with wlroots and sway in terms of general approach and coding style.
  Labwc only understands wayland-protocols & wlr-protocols, and it cannot be controlled with dbus, sway/i3-IPC or other technology. The reason for this is that we believe that custom IPCs and protocols create a fragmentation that hinders general Wayland adoption.

## Installation

Labwc can be installed with the packages labwc or labwc-gitAUR.

The default terminal emulator is alacritty. Before starting labwc it is advisable to either install it or set a new terminal in the configuration.

## Starting

Like all wlroots-based compositors, for access to your seat, labwc requires Polkit to be installed when using systemd-logind(8), or seatd service to be enabled with your user added to the `seat` user group.

You can start labwc in the Linux console, use a Wayland-compatible Display manager, or also see Wayland#Autostart wayland compositor as systemd service.

By default, you can press `Super` (usually a key with a Window icon) with `Enter` to launch alacritty. See 6. Usage for the default keybindings.

## Configuration

This article or section needs language, wiki syntax or style improvements. See Help:Style for reference.

Reason: Multiple sections duplicate upstream documentation. (Discuss in Talk:Labwc)

Following files can be used for configuration:

- `~/.config/labwc/rc.xml` - for general configuration
- `~/.config/labwc/menu.xml` - for menu layout
- `~/.config/labwc/autostart` - script executed when launching labwc
- `~/.config/labwc/shutdown` - script executed when exiting labwc
- `~/.config/labwc/environment` - for environment variables in the session
- `~/.config/labwc/themerc-override` - for additional theme settings

Example files are provided in `/usr/share/doc/labwc/`. Especially, `/usr/share/doc/labwc/rc.xml.all` contains all the default configurations.

See labwc-config(5) for further details.

### Autostart

`~/.config/labwc/autostart` contains a shell script executed when launching labwc. For example:

    ~/.config/labwc/autostart

    kanshi >/dev/null 2>&1 &
    waybar >/dev/null 2>&1 &
    swaybg -i ~/Pictures/background.png >/dev/null 2>&1 &
    lxqt-policykit-agent >/dev/null 2>&1 &
    mako >/dev/null 2>&1 &
    gammastep -O 3500 -b 0.8 >/dev/null 2>&1 &

### Keymap

The keyboard layout can be configured by setting environment variables in `~/.config/labwc/environment`. For example:

    ~/.config/labwc/environment

    XKB_DEFAULT_LAYOUT=us
    XKB_DEFAULT_LAYOUT=us,de
    XKB_DEFAULT_OPTIONS=grp:alt_shift_toggle
    XKB_DEFAULT_OPTIONS=grp:shift_caps_toggle

See xkeyboard-config(7) for details.

### Statusbar

Use external tools like waybar and sfwbarAUR can be used to show status bars. For example:

    ~/.config/labwc/autostart

    waybar >/dev/null 2>&1 &

### Outputs

Use external tools like wlr-randr and kanshi can be used to manage outputs. For example:

    ~/.config/labwc/autostart

    wlr-randr --output HDMI-A-2 --preferred --pos 0,0 --output HDMI-A-1 --preferred --pos -1920,0

#### Wallpaper

Use external tools like swaybg, wpaperd and wbgAUR can be used to show backgrounds. For example:

    ~/.config/labwc/autostart

    swaybg -c '#113344' >/dev/null 2>&1 &

### Custom keybindings

Keybindings are configured by adding `<keyboard><keybind>` sections with `<action>`. For example:

    ~/.config/labwc/rc.xml

    <labwc_config>
      <keyboard>
        <keybind key="W-q"><action name="Close" /></keybind>
        <keybind key="A-Tab"><action name="NextWindow" /></keybind>
        <keybind key="W-Tab"><action name="ToggleMaximize" /></keybind>
        <keybind key="W-s"><action name="Execute" command="foot" /></keybind>
        <keybind key="W-a"><action name="Execute" command="fuzzel" /></keybind>
      </keyboard>
    </labwc_config>

#### Workspaces

Workspaces are configured in `<desktops>` section and switched with keybindings. For example:

    ~/.config/labwc/rc.xml

    <labwc_config>
      <desktops number="4" />
      <keyboard>
        <keybind key="W-1"><action name="GoToDesktop" to="1" /></keybind>
        <keybind key="W-2"><action name="GoToDesktop" to="2" /></keybind>
        <keybind key="W-3"><action name="GoToDesktop" to="3" /></keybind>
        <keybind key="W-4"><action name="GoToDesktop" to="4" /></keybind>
      </keyboard>
    </labwc_config>

### Menu

Labwc follows Openbox's syntax for menu configuration in `~/.config/labwc/menu.xml`. For example:

    ~/.config/labwc/menu.xml

    <?xml version="1.0" ?>
    <openbox_menu>
      <menu id="root-menu" label="">
        <item label="󰈹   Firefox">
          <action name="Execute" command="firefox" />
        </item>
        <item label="  Terminal">
          <action name="Execute" command="foot" />
        </item>
      </menu>
    </openbox_menu>

Also, you can use menu generators for Openbox like archlinux-xdg-menu and obmenu-generatorAUR.

See labwc-menu(5) for details.

### Themes

Labwc loosely follows Openbox 3 theme specification. You can install themes to the following directories:

- `~/.local/share/themes/<theme-name>/openbox-3/`
- `~/.themes/<theme-name>/openbox-3/`
- `/usr/share/themes/<theme-name>/openbox-3/`
- `/usr/local/share/themes/<theme-name>/openbox-3/`
- `/opt/share/themes/<theme-name>/openbox-3/`

These directories contain `themerc` which defines the theme colors and geometries, and button icon files like `close-active.svg` and `close-inactive.svg`. XBM, SVG and PNG formats are supported for icon files.

Additionally, you can override the theme entries with `~/.config/themerc-override`.

labwc-artwork provides some themes for labwc.

See labwc-theme(5) for details.

### Xwayland

xorg-xwayland starts automatically if Xwayland support is enabled at build time. To force disable it, set:

    ~/.config/labwc/environment

    WLR_XWAYLAND=

### wlroots renderer

To use another renderer such as vulkan, see Wayland#Use another renderer for wlroots based compositor.
