+
+        <para>Starting with version 4.2.6, VirtualBox comes with an own greeter
+        module named vbox-greeter which can be used with LightDM 1.0.1 or later.
+        LightDM is the default display manager since Ubuntu 10.11 and therefore
+        also can be used for automated guest logons.</para>
+
+        <para>vbox-greeter does not need the pam_vbox module described above
+        in order to function -- it comes with its own authentication mechanism
+        provided by LightDM. However, to provide maximum of flexibility both
+        modules can be used together on the same guest.</para>
+
+        <para>As for the pam_vbox module, vbox-greeter is shipped as part of
+        the Guest Additions but it is not installed and/or activated on the
+        guest OS by default. In order to install it, the
+        <computeroutput>vbox-greeter.desktop</computeroutput>
+        file has to be copied from
+        <computeroutput>/opt/VBoxGuestAdditions-&lt;version&gt;</computeroutput>
+        to the <computeroutput>xgreeters</computeroutput> directory, usually
+        <computeroutput>/usr/share/xgreeters/</computeroutput>.
+        Please refer to your guest OS documentation for the correct LightDM
+        greeter directory.</para>
+
+        <para>The vbox-greeter module itself already was installed by the
+        VirtualBox Guest Additions installer and resides in
+        <computeroutput>/usr/sbin/</computeroutput>. To enable vbox-greeter as
+        the standard greeter module, the file
+        <computeroutput>/etc/lightdm/lightdm.conf</computeroutput> needs to be
+        edited:</para>

+
+        <note><para>The LightDM server needs to be fully restarted in order to
+        get vbox-greeter used as the default greeter. As root, do a
+        <computeroutput>service lightdm --full-restart</computeroutput> on
+        Ubuntu, or simply restart the guest.</para></note>
+
+        <note><para>vbox-greeter is independent of the graphical session chosen
+        by the user (like Gnome, KDE, Unity etc). However it requires FLTK 1.3
+        for representing its user interface.</para></note>

+        <para>In addition to the guest property values of the
