       --session-bus
              Attempt to connect to the display manager using the session bus.  This is useful if
              you are running a display manager in a test mode.  If this option  is  not  present
              dm-tool will connect using the system bus.

       The following commands are available:

       switch-to-greeter
              Switch to the greeter suitable for logging into a new session.

       switch-to-user USERNAME [SESSION]
              Switch  to  a  user  session.   If  this user is already logged in then the display
              manager will switch to that session,  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 to this session by authenticating in the greeter.

              List the active seats and sessions that are running.
