configuration files

Configuration

Labwc uses openbox-3.6 specification for configuration and theming, but does not support all options. The following files form the basis of the labwc configuration: rc.xml, menu.xml, autostart and environment.

No configuration files are needed to start and run labwc.

In accordance with XDG Base Directory Specification, configuration files are searched for in the following order:

  • ${XDG_CONFIG_HOME:-$HOME/.config}/labwc
  • ${XDG_CONFIG_DIRS:-/etc/xdg}/labwc

All configuration and theme files except autostart are re-loaded on receiving signal SIGHUP.

The autostart file is executed as a shell script. This is the place for executing clients for handling background images, panels and similar.

The environment file is parsed as variable=value and sets environment variables accordingly. It is recommended to specify keyboard layout settings and cursor size/theme here; see environment variable section below for details. Note that the environment file is treated differently by openbox where it is simply sourced prior to running openbox.

The menu.xml file defines the context/root-menus and is described in labwc-menu(5)

There is a small <theme> section in rc.xml, for example to set rouned corners, but the remainder of the theme specification and associated files are described in labwc-theme(5).

rc.xml is the main configuration file and all its options are described in detail below. Configuration must be wrapped in a <labwc_config> root-element, like this:

  <?xml version="1.0"?>
  <labwc_config>

<!-- settings -->


</labwc_config>

The rest of this man page describes configuration options.

Core

<core><decoration> [server|client]

Specify server or client side decorations for xdg-shell views. Note that it is not always possible to turn off client side decorations. Default is server.

<core><gap>

Enable adaptive sync. Default is no.

<core><cycleViewPreview> [yes|no]

Preview the contents of the selected window when cycling between windows. Default is no.

<core><cycleViewOutlines> [yes|no]

Draw an outline around the selected window when cycling between windows. Default is yes.

Resistance

<resistance><screenEdgeStrength>

Screen Edge Strength is how far past the screen's edge your cursor must move before the window will move with it. Resistance is counted in pixels. Default is 20 pixels.

Focus

Maximize window if Move operation ends on the top edge. Default is yes.

Workspaces

<desktops><names><name>

Define workspaces. A workspace covers all outputs. The OSD only shows windows on the current workspace. Workspaces can be switched to with GoToDesktop and windows can be moved with SendToDesktop. See labwc-actions(5) for more information about their arguments.

<desktops><popupTime>

Define the timeout after which to hide the workspace OSD. A setting of 0 disables the OSD. Default is 1000 ms.

<keyboard><keybind key=""><action name="">

Keybind action. See labwc-action(5)

<keyboard><default />

Load the default keybinds listed below. This is an addition to the openbox specification and provides a way to keep config files simpler whilst allowing your specific keybinds. Note that if no rc.xml is found, or if no <keyboard><keybind> entries exist, the same default keybinds will be loaded even if the <default /> element is not provided.

    A-Tab - next window
    W-Return - alacritty
    A-F3 - run bemenu
    A-F4 - close window
    W-a - toggle maximize
    A-<arrow> - move window to edge
    W-<arrow> - resize window to fill half the output

Audio and MonBrightness keys are also bound to amixer and brightnessctl respectively

<keyboard><repeatRate>

<mouse><context name=""><mousebind button="" direction=""><action>

Multiple <mousebind> can exist within one <context>; and multiple <action> can exist within one <mousebind>

Define a mouse binding. Supported context-names include:

  • TitleBar: The decoration on top of the window, where the window buttons and the window title are shown.

  • Bottom: The bottom edge of the window's border.
  • Left: The left edge of the window's border.
  • Right: The right edge of the window's border.
  • TRCorner: The top-right corner of the window's border.
  • TLCorner: The top-left corner of the window's border.
  • BLCorner: The bottom-left corner of the window's border.
  • BRCorner: The bottom-right edge of the window's border.

Scroll actions must have a direction specified instead of button.

<mouse><default />

Load default mousebinds. This is an addition to the openbox specification and provides a way to keep config files simpler whilst allowing user specific binds.  Note that if no rc.xml is found, or if no <mouse><mousebind> entries exist, the same default mousebinds will be loaded even if the <default /> element is not provided.

Libinput

<libinput><device category="">

Define a category of devices to use the configuration values that follow. The category can be set to touch (devices that define a width and height), non-touch, default, or the name of a device. You can obtain your devices name by running libinput list-devices (you may need to be root or a part of the input group to perform this.) Any members of this category that are not set use the default for the device. With the exception of tap-to-click, which is enabled by default.

<libinput><device category=""><naturalScroll> [yes|no]

Use natural scrolling for this category if available.

<libinput><device category=""><leftHanded> [yes|no]

Use your devices left-handed mode if available.

<libinput><device category=""><pointerSpeed> [-1.0 to 1.0]

Set the pointer speed for this category. The speed is a number between -1.0 and 1.0, with 0.0 being the default in most cases, and 1.0 being the fastest.

<libinput><device category=""><accelProfile> [flat|adaptive]

Set the pointer's acceleration profile for this category. Flat applies no acceleration (the pointers velocity is constant), while adaptive changes the pointers speed based the actual speed of your mouse or finger on your touchpad.

<libinput><device category=""><tap> [yes|no]

Enable or disable tap-to-click for this category. This is enabled by default for all categories.

<libinput><device category=""><tapButtonMap> [lrm|lmr]

Set the buttons mapped to one-, two-, and three-finger taps to the left button, right button, and middle button, respectively (lrm) (the default), or to left button, middle button, and right button (lmr).

<libinput><device category=""><middleEmulation> [yes|no]

Enable or disable middle button emulation for this category. Middle emulation processes a simultaneous left and right click as a press of the middle mouse button (scroll wheel).

<libinput>device category=""><disableWhileTyping> [yes|no]

Enable or disable disable while typing for this category. DWT ignores any motion events while a keyboard is typing, and for a short while after as well.

Environment Variables

XCURSOR_THEME and XCURSOR_SIZE are supported to set cursor theme and size respectively. The default size is 24. System cursor themes can typically be found with a command such as:

  find /usr/share/icons/ -type d -name "cursors"

The following keyboard-configuration variables are supported: XKB_DEFAULT_RULES, XKB_DEFAULT_MODEL, XKB_DEFAULT_LAYOUT, XKB_DEFAULT_VARIANT and XKB_DEFAULT_OPTIONS.

See xkeyboard-config(7) for details.
