I'm not completely sure what you need, but it's likely one of those:

Command-line options:

       -l and -ln
            turns login mode on or off (for /var/run/utmp updating).
            This can also be defined through the "deflogin" .screenrc
            command.

       -d -m
            Start screen in "detached" mode. This creates a new
            session but doesn't attach to it. This is useful for
            system startup scripts.

       -D -m
            This also starts screen in "detached" mode, but doesn't
            fork a new process. The command exits if the session
            terminates.

Commands for .screenrc:

       deflogin on|off

       Same as the login command except that the default setting for
       new windows is changed. This is initialized with `on' as
       distributed (see config.h.in).

       login [on|off]

       Adds or removes the entry in the utmp database file for the
       current window.  This controls if the window is `logged in'.
       When no parameter is given, the login state of the window is
       toggled. Additionally to that toggle, it is convenient having a
       `log in' and a `log out' key. E.g. `bind I login on' and `bind
       O login off' will map these keys to be C-a I and C-a O. The
       default setting (in config.h.in) should be "on" for a screen
       that runs under suid-root. Use the "deflogin" command to change
       the default login state for new windows. Both commands are only
       present when screen has been compiled with utmp support.

                Kind regards, Axel
