Nitrux uses greetd as the login daemon and QMLGreet as the graphical greeter.
What is greetd?
greetd is a minimal, agnostic login daemon. It handles user authentication and session startup without being tied to a specific display server or desktop environment.
What is QMLGreet?
QMLGreet is a modern, lightweight greeter (login screen) designed for greetd and built with MauiKit to deliver a polished, consistent user interface.
QMLGreet runs natively on Wayland compositors (such as Hyprland or Sway) using the Layer Shell protocol.
Session support
Nitrux only supports Wayland sessions (Hyprland). X11 sessions are not available, even though greetd technically supports them.
Configuration
The greetd configuration file is located at /etc/qtgreet/config.ini.
The QMLGreet configuration file is located at /etc/qmlgreet/qmlgreet.conf.
