If all is well, the configuration
file needs to be installed in a common location where
<citerefentry vendor="xorg"><refentrytitle>Xorg
</refentrytitle><manvolnum>1
</manvolnum></citerefentry> can find it. This is typically
<filename>/etc/X11/xorg.conf
</filename> or
<filename>/usr/local/etc/X11/xorg.conf
</filename>.
