Swaylock [1] is a screen locking utility for Wayland compositors, use mainly by Sway [2]. It was part of dev-libs/sway and now is a standalone project (see bug #675978). It is compatible with any Wayland compositor which implements the required Wayland protocols. I'm going to open a PR on Github with the ebuild I've written for Swaylock. I'll also add myself as proxy maintainer. [1] https://github.com/swaywm/swaylock [2] https://swaywm.org/ https://github.com/swaywm/sway
