      <para>
        If you are not using <application>gdm</application> to start your
        <application>GNOME</application> desktop, you will need to invoke
        <command>gnome-session</command> <emphasis>instead of</emphasis> invoking
        a window-manager directly.  All of the packages in the 'Desktop' section of
        this chapter need to be installed first, and some of the 'Applications' - 
        particularly <application>GNOME Terminal</application>
        (<application>xterm</application> does not  install a '.desktop' file and
        so not appear in the menus).
      </para>

      <para>
        When <command>gnome-session</command> is run, it invokes the necessary
        daemons and either <application>Metacity</application> or
        <application>gnome-shell</application>. A desktop manager such as
        <application>gdm</application> will invoke <application>ConsoleKit</application>
        before the window manager, but if you use <command>startx</command> the first
        invocation after booting may fail because the daemon is not already running,
        so we will invoke it first.
      </para>

      <para>
        To automatically start the <application>gnome-session</application>
        window manager when you issue the <command>startx</command> command,
        backup your current <filename>~/.xinitrc</filename> before proceeding.
        Note that you will be able to invoke <application>GNOME Terminal</application>
        from the menu, so there is no reason to invoke xterm here. Create a new
        <filename>.xinitrc</filename> using this command:
