The foundation for many embedded graphical display implementations. ubuntu-frame is a simple fullscreen shell (based on Wayland) used for kiosks, industrial displays, digital signage, smart mirrors, etc.

The application you choose (or provide) gets a fullscreen window (or windows) and input from touch, keyboard and mouse without needing to deal with the specific hardware.
Configuration

There are three snap configuration options:

    daemon=[true|false] enables the daemon (defaults to false on classic systems)
    config=<options for the shell>
    display=<options for display layout>
