swaylock is a screen locking utility for Wayland compositors. It is compatible
with any Wayland compositor which implements one of the following Wayland
protocols:

- ext-session-lock-v1, or
- wlr-layer-shell and wlr-input-inhibitor

See the man page, `swaylock(1)`, for instructions on using swaylock.

## Release Signatures

Releases are signed with [E88F5E48](https://keys.openpgp.org/search?q=34FF9526CFEF0E97A340E2E40FDE7BE0E88F5E48)
and published [on GitHub](https://github.com/swaywm/swaylock/releases). swaylock
releases are managed independently of sway releases.

## Installation

### From Packages

Swaylock is available in many distributions. Try installing the "swaylock"
package for yours.

### Compiling from Source

Install dependencies:

* meson \*
* wayland
* wayland-protocols \*
* libxkbcommon
* cairo
* gdk-pixbuf2 \*\*
* pam (optional)
* [scdoc](https://git.sr.ht/~sircmpwn/scdoc) (optional: man pages) \*
* git \*

_\* Compile-time dep_  
_\*\* Optional: required for background images other than PNG_

Run these commands:

meson build
    ninja -C build
    sudo ninja -C build install

On systems without PAM, you need to suid the swaylock binary:

sudo chmod a+s /usr/local/bin/swaylock

Swaylock will drop root permissions shortly after startup.

# NAME

swaylock - Screen locker for Wayland

# SYNOPSIS

_swaylock_ [options...]

Locks your Wayland session.

# OPTIONS

*-C, --config* <path>
	The config file to use. By default, the following paths are checked:
	_$HOME/.swaylock/config_, _$XDG\_CONFIG\_HOME/swaylock/config_, and
	_SYSCONFDIR/swaylock/config_. All flags aside from this one are valid
	options in the configuration file using the format _long-option=value_.
	For options such as _ignore-empty-password_, just supply the _long-option_.
	All leading dashes should be omitted and the equals sign is required for
	flags that take an argument.

*-d, --debug*
	Enable debugging output.

*-e, --ignore-empty-password*
	When an empty password is provided, do not validate it.

*-F, --show-failed-attempts*
	Show current count of failed authentication attempts.

*-f, --daemonize*
	Detach from the controlling terminal after locking.

Note: this is the default behavior of i3lock.

*-h, --help*
	Show help message and quit.

*-v, --version*
	Show the version number and quit.

# APPEARANCE

*-u, --no-unlock-indicator*
	Disable the unlock indicator.

*-i, --image* [[<output>]:]<path>
	Display the given image, optionally only on the given output. Use -c to set
	a background color. If the path potentially contains a ':', prefix it with another
	':' to prevent interpreting part of it as <output>.

*-k, --show-keyboard-layout*
	Display the current xkb layout while typing.

*-K, --hide-keyboard-layout*
	Force hiding the current xkb layout while typing, even if more than one layout
	is configured or the show-keyboard-layout option is set.

*-L, --disable-caps-lock-text*
	Disable the Caps Lock text.

*-l, --indicator-caps-lock*
	Show the current Caps Lock state also on the indicator.

*-s, --scaling*
	Image scaling mode: _stretch_, _fill_, _fit_, _center_, _tile_,
	_solid\_color_. Use _solid\_color_ to display only the background color, even
	if a background image is specified.

*-t, --tiling*
	Same as --scaling=tile.

*-c, --color* <rrggbb[aa]>
	Turn the screen into the given color instead of white. If -i is used, this
	sets the background of the image to the given color. Defaults to white
	(FFFFFF).

*--bs-hl-color* <rrggbb[aa]>
	Sets the color of backspace highlight segments.

*--caps-lock-bs-hl-color* <rrggbb[aa]>
	Sets the color of backspace highlight segments when Caps Lock is active.

*--caps-lock-key-hl-color* <rrggbb[aa]>
	Sets the color of the key press highlight segments when Caps Lock is active.

*--font* <font>
	Sets the font of the text.

*--font-size* <size>
	Sets a fixed font size for the indicator text.

*--indicator-idle-visible*
	Sets the indicator to show even if idle.

*--indicator-radius* <radius>
	Sets the indicator radius. The default value is 50.

*--indicator-thickness* <thickness>
	Sets the indicator thickness. The default value is 10.

*--indicator-x-position* <x>
	Sets the horizontal position of the indicator.

*--indicator-y-position* <y>
	Sets the vertical position of the indicator.

*--inside-color* <rrggbb[aa]>
	Sets the color of the inside of the indicator.

*--inside-clear-color* <rrggbb[aa]>
	Sets the color of the inside of the indicator when cleared.

*--inside-caps-lock-color* <rrggbb[aa]>
	Sets the color of the inside of the indicator when Caps Lock is active.

*--inside-ver-color* <rrggbb[aa]>
	Sets the color of the inside of the indicator when verifying.

*--inside-wrong-color* <rrggbb[aa]>
	Sets the color of the inside of the indicator when invalid.

*--key-hl-color* <rrggbb[aa]>
	Sets the color of the key press highlight segments.

*--layout-bg-color* <rrggbb[aa]>
	Sets the background color of the box containing the layout text.

*--layout-border-color* <rrggbb[aa]>
	Sets the color of the border of the box containing the layout text.

*--layout-text-color* <rrggbb[aa]>
	Sets the color of the layout text.

*--line-color* <rrggbb[aa]>
	Sets the color of the line between the inside and ring.

*--line-clear-color* <rrggbb[aa]>
	Sets the color of the line between the inside and ring when cleared.

*--line-caps-lock-color* <rrggbb[aa]>
	Sets the color of the line between the inside and ring when Caps Lock is
	active.

    <description summary="create surfaces that are layers of the desktop">
      Clients can use this interface to assign the surface_layer role to
      wl_surfaces. Such surfaces are assigned to a "layer" of the output and
      rendered with a defined z-depth respective to each other. They may also be
      anchored to the edges and corners of a screen and specify input handling
      semantics. This interface should be suitable for the implementation of
      many desktop shell components, and a broad number of other applications
      that interact with the desktop.

      <description summary="create a layer_surface from a surface">
        Create a layer surface for an existing surface. This assigns the role of
        layer_surface, or raises a protocol error if another role is already
        assigned.

Creating a layer surface from a wl_surface which has a buffer attached
        or committed is a client error, and any attempts by a client to attach
        or manipulate a buffer prior to the first layer_surface.configure call
        must also be treated as errors.

You may pass NULL for output to allow the compositor to decide which
        output to use. Generally this will be the one that the user most
        recently interacted with.

Clients can specify a namespace that defines the purpose of the layer
        surface.

        Sets the size of the surface in surface-local coordinates. The

        anchors.

If you pass 0 for either value, the compositor will assign it and
        inform you of the assignment in the configure event. You must set your
        anchor to opposite edges in the dimensions you omit; not doing so is a
        protocol error. Both values are 0 by default.

Size is double-buffered, see wl_surface.commit.

<request name="set_anchor">
      <description summary="configures the anchor point of the surface">
        Requests that the compositor anchor the surface to the specified edges
        and corners. If two orthoginal edges are specified (e.g. 'top' and
        'left'), then the anchor point will be the intersection of the edges
        (e.g. the top left corner of the output); otherwise the anchor point
        will be centered on that edge, or in the center if none is specified.

Anchor is double-buffered, see wl_surface.commit.

<request name="set_exclusive_zone">
      <description summary="configures the exclusive geometry of this surface">
        Requests that the compositor avoids occluding an area of the surface
        with other surfaces. The compositor's use of this information is
        implementation-dependent - do not assume that this region will not
        actually be occluded.

A positive value is only meaningful if the surface is anchored to an
        edge, rather than a corner. The zone is the number of surface-local
        coordinates from the edge that are considered exclusive.

Surfaces that do not wish to have an exclusive zone may instead specify
        how they should interact with surfaces that do. If set to zero, the
        surface indicates that it would like to be moved to avoid occluding
        surfaces with a positive excluzive zone. If set to -1, the surface
        indicates that it would not like to be moved to accommodate for other
        surfaces, and the compositor should extend it all the way to the edges
        it is anchored to.

For example, a panel might set its exclusive zone to 10, so that
        maximized shell surfaces are not shown on top of it. A notification
        might set its exclusive zone to 0, so that it is moved to avoid
        occluding the panel, but shell surfaces are shown underneath it. A
        wallpaper or lock screen might set their exclusive zone to -1, so that
        they stretch below or over the panel.

The default value is 0.

Exclusive zone is double-buffered, see wl_surface.commit.

The exclusive zone includes the margin.

Margin is double-buffered, see wl_surface.commit.

        seat will always give exclusive keyboard focus to the top-most layer
        which has keyboard interactivity set to true.

Layer surfaces receive pointer, touch, and tablet events normally. If
        you do not want to receive them, set the input region on your surface

If the client receives multiple configure events before it
        can respond to one, it only has to ack the last configure event.

A client is not required to commit immediately after sending
        an ack_configure request - it may even ack_configure several times
        before its next surface commit.

A client may send multiple ack_configure requests before committing, but
        only the last request sent before a commit indicates which configure

Clients should arrange their surface for the new states, and then send

The client is free to dismiss all but the last configure event it
        received.

The width and height arguments specify the size of the window in
        surface-local coordinates.

The size is a hint, in the sense that the client is free to ignore it if
        it doesn't resize, pick a smaller size (to satisfy aspect ratio or
        resize in steps of NxM pixels). If the client picks a smaller size and
        is anchored to two opposite anchors (e.g. 'top' and 'bottom'), the
        surface will be centered on this axis.

If the width or height arguments are zero, it means the client should
