       --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.

       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.
