       --session-bus

       switch-to-user USERNAME [SESSION]

	      sion, otherwise a new session is started.	 If authentication is required a greeter will start to collect this.
	      If the session option is provided then this session type will be used, otherwise the default for this user  is
	      used.

       switch-to-guest [SESSION]
	      Switch  to  a  guest  session.  If the guest session is already active the display manager will switch to that
	      session, otherwise the guest session is started.	If the session option is provided  then	 this  session	type
	      will be used, otherwise the default for the guest user is used.

       lock   Lock  the	 current seat.	This will switch to a greeter with a hint that the screen is locked.  You can return

	      a	 display-manager  use its list-seats command to show active sessions and set the session to connect to with:
	      export XDG_SEAT_PATH=/org/freedesktop/DisplayManager/SeatX where SeatX is one of the listed sessions.
