Additional configuration files are searched for in the following
directories when the server is started as a normal user:
/etc/X11/<cmdline>
/etc/X11/<cmdline>
/etc/X11/xorg.conf.d
/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>
/etc/X11/<cmdline>
/etc/X11/xorg.conf.d
/etc/X11/xorg.conf.d
where <cmdline> is the path specified with the -configdir command line
option (which may be absolute or relative).
