      <para>
        If you use <application>Linux PAM</application> you need to
        configure <application>Linux PAM</application> to activate
        <application>ConsoleKit</application> upon user login.
        This can be achieved by editing the 
        <filename>/etc/pam.d/system-session</filename> file as the 
        <systemitem class="username">root</systemitem> user:
      </para>

session   optional    pam_ck_connector.so nox11

# End ConsoleKit addition

      <para>
        You will also need a helper script that creates a file in
        <filename class="directory">/var/run/console</filename>
        named as the currently logged in user and that contains the
        <application>D-Bus</application> address of the session. You
        can create the script by running the following commands as
        the <systemitem class="username">root</systemitem> user:

<screen role="root"><userinput>cat &gt; /usr/lib/ConsoleKit/run-session.d/pam-foreground-compat.ck &lt;&lt; "EOF"
