Legacy displaymanagers are heavily relying on the design of the xserver, such as detecting if a window manager grabs the root window. Since wayland is getting more and more attention on modern distributions, its time for something which is, platform independent, toolkit independent and lightweight.

Spawny is a software that aims for this. It has a minimal API for a reliable way of logging a user into a system. Core design decisions are: - Always giving a user the possibility to login, even after sessions are crashing - Support every single application that can be started from a tty, as a session in a greeter UI

The presentation will give a overview of a few design decisions, core features, how it works, and how to work with it.
