Introducing µlock
Read OriginalThis article presents µlock (ulock), a minimal Wayland screen-locker for Linux that operates without relying on setuid binaries by using the tcb password shadowing scheme. It is built with Hare and Wayland, shows system uptime on locked displays, and provides visual feedback during password entry. The author shares their experience using it daily, fixing bugs, and the unexpected appreciation of seeing uptime. The project is hosted on sourcehut, compiles to a single binary, and requires only libxkbcommon. This is a technical hobby project focused on Linux system programming and Wayland development.
