# swaylock

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

- wlr-layer-shell + wlr-input-inhibitor, or ext-session-lock-v1
- xdg-output
- xdg-shell

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