>+        <answer>
>+          <para>All X servers need to be run as root in order to get direct
>+            access to your video hardware.  Older versions of XFree86
>+            (&lt;= 3.3.6) installed all bundled servers to be automatically
>+            run as root (setuid to root).  This is obviously a security
>+            hazard because X servers are large, complicated programs.
>+            Newer versions of XFree86 do not install the servers setuid to
>+            root for just this reason.</para>
>+
>+          <para>Obviously, running an X server as the root user is not
>+            acceptable, nor a good idea security-wise.  There are two ways
>+            to be able to use X as a regular user.  The first is to use
>+            <ulink
>+            url="http://www.FreeBSD.org/cgi/man.cgi?manpath=xfree86&amp;query=xdm">
>+            <command>xdm</command></ulink> or another display manager
>+            (e.g., <command>kdm</command>); the second is to use the
>+            <command>Xwrapper</command>.</para>
>+
>+          <para><command>xdm</command> is a daemon that handles graphical
>+            logins.  It is usually started at boot time, and is responsible
>+            for authenticating users and starting their sessions; it is
>+            essentially the graphical counterpart of
>+            <command>getty</command> and <command>login</command>.  For
>+            more information on <command>xdm</command> see <ulink
>+            url="http://www.FreeBSD.org/cgi/man.cgi?manpath=xfree86&amp;query=xdm">
>+            its manual page</ulink>, <ulink
>+            url="http://www.xfree86.org/support.html">the XFree86
>+            documentation</ulink>, and the <link linkend="xdm-boot">the FAQ
>+            entry</link> on it.</para>
>+
>+          <para><command>Xwrapper</command> is the X server wrapper; it is
>+            a small utility to enable one to manually run an X server while
>+            maintaining reasonable safety.  It performs some sanity checks
>+            on the command line arguments given, and if they pass, runs the
>+            appropriate X server.  If you do not want to run a display
>+            manger for whatever reason, this is for you.  If you have
>+            installed the complete <ulink url="../ports/">ports
>+            collection</ulink>, you can find the port in
>+            <filename>/usr/ports/x11/wrapper</filename>.  If you have not,
>+            follow the previous link for information on how to obtain just
>+            this specific port.</para>
