Screen Lock

To configure a user to be automatically logged into the Desktop at system startup, use the following Hiera keys:

gnome::lock_enabled: enable/disable screen lock (default true)
gnome::idle_delay: idle time in seconds until the screen switched off (default 5 minutes)
gnome::lock_delay: time in seconds between screen switched off and actually being locked (default 0)

Example:

gnome::lock_enabled: true
gnome::idle_delay: 900
gnome::lock_delay: 15

This is only implemented for Gnome desktop (default) and not yet for XFCE or any other desktop/window manager.
