waylock
Waylock is a small screenlocker for Wayland compositors implementing
ext-session-lock-v1. The ext-session-lock-v1 protocol is significantly
more robust than previous client-side Wayland screen locking approaches.
Importantly, the screenlocker crashing does not cause the session to be
unlocked.
In addition, waylock has been entirely rewritten since version 0.3.5 for security and simplicity. It now benefits from everything I've learned about Wayland and programming in general over the past few years working on river.
Building
On cloning the repository, you must init and update the submodules as well with e.g.
git submodule update --init
To compile waylock first ensure that you have the following dependencies installed:
- zig 0.10
- wayland
- wayland-protocols
- xkbcommon
- pam
- pkg-config
- scdoc (optional, but required for man page generation)
Then run, for example:
zig build -Drelease-safe --prefix /usr install
Note that PAM will only use configuration files in the system directory,
likely /etc/pam.d by default. Therefore care must be taken if
installing to a prefix other than /usr to ensure the configuration file
pam.d/waylock is found by PAM.
If you are packaging waylock for distribution, see also PACKAGING.md.
Usage
See the waylock(1) man page or the output of waylock -h for an overview
of the command line options.
Run the waylock executable to lock the session. All monitors will be
blanked with the -init-color. Typing causes the color to change to the
-input-color, to clear what you've typed press Esc or Ctrl-U.
To unlock the session, type your password and press Enter. If the password
is correct, waylock will unlock the session and exit. Otherwise, the color
will change to the -fail-color and you may try again.
Licensing
Waylock is released under the ISC License.
