       When the Xorg server is started by the “root” user, the config file
       search locations are as follows:

           <cmdline>
           /etc/X11/<cmdline>
           /usr/local/etc/X11/<cmdline>
           $XORGCONFIG
           /etc/X11/$XORGCONFIG
           /usr/local/etc/X11/$XORGCONFIG
           /etc/X11/xorg.conf
           /etc/xorg.conf
           /usr/local/etc/X11/xorg.conf.<hostname>
           /usr/local/etc/X11/xorg.conf
           /usr/local/lib/X11/xorg.conf.<hostname>
           /usr/local/lib/X11/xorg.conf

       where <cmdline> is the path specified with the -config command line
       option (which may be absolute or relative), $XORGCONFIG is the path
       specified by that environment variable (absolute or relative), $HOME is
       the path specified by that environment variable (usually the home
       directory), and <hostname> is the machine's hostname as reported by
       gethostname(3).

       Additional configuration files are searched for in the following
       directories when the server is started as a normal user:

           /etc/X11/<cmdline>
           /usr/local/etc/X11/<cmdline>
           /etc/X11/xorg.conf.d
           /usr/local/etc/X11/xorg.conf.d

       where <cmdline> is a relative path (with no “..” components) specified
       with the -configdir command line option.

       When the Xorg server is started by the “root” user, the config
       directory search locations are as follows:

           <cmdline>
           /etc/X11/<cmdline>
           /usr/local/etc/X11/<cmdline>
           /etc/X11/xorg.conf.d
           /usr/local/etc/X11/xorg.conf.d

       where <cmdline> is the path specified with the -configdir command line
       option (which may be absolute or relative).

       Finally, configuration files will also be searched for in a directory
       reserved for system use.  This is to separate configuration files from
       the vendor or 3rd party packages from those of local administration.
       These files are found in the following directory:

           /usr/local/share/X11/xorg.conf.d

       When the Xorg server is started by the “root” user, the config file
       search locations are as follows:

           <cmdline>
           /etc/X11/<cmdline>
           /usr/local/etc/X11/<cmdline>
           $XORGCONFIG
           /etc/X11/$XORGCONFIG
           /usr/local/etc/X11/$XORGCONFIG
           /etc/X11/xorg.conf
           /etc/xorg.conf
           /usr/local/etc/X11/xorg.conf.<hostname>
           /usr/local/etc/X11/xorg.conf
           /usr/local/lib/X11/xorg.conf.<hostname>
           /usr/local/lib/X11/xorg.conf

       where <cmdline> is the path specified with the -config command line
       option (which may be absolute or relative), $XORGCONFIG is the path
       specified by that environment variable (absolute or relative), $HOME is
       the path specified by that environment variable (usually the home
       directory), and <hostname> is the machine's hostname as reported by
