This provides the boilerplate for using mir_kiosk_x11 for a confined desktop session.
It is intended for use as a stage-snap and provides the essentials to create a confined desktop session with a single fullscreen application. The resulting snap needs registering with the desktop manager by running:
/snap/NAME_OF_SNAP/current/desktop/setup
And also connecting the login-session-control and 'hardware-observe' interfaces:
snap connect NAME_OF_SNAP:login-session-control
snap connect NAME_OF_SNAP:hardware-observe
There are certain elements that needed to be included in the final snap:
parts:
mir-kiosk-desktop:
plugin: nil
stage-snaps: [mir-kiosk-desktop]
