It's a stupid issue with distcheck. It's trying to do a non-DESTDIR
install with --prefix=$tmpdir or something like that, but using the
directory from xorg-server.pc means the file won't be under $prefix.
So, the way to fix it is to set DISTCHECK_CONFIGURE_FLAGS =
--with-xorg-conf-dir='$${datadir}/X11/xorg.conf.d' in the top-level
Makefile.am.

It's kind of delicate. I think it should be done unconditionally, but
it might cause user configuration regressions. Since the settings in
xorg.conf.d will override the backend supplied options (fdi settings
in the case of hal), you could end up overloading some user's setup.
Ultimately, this is the way to go to be compatible with any server
backend, whether udev or hal or some other fictitious service, so I
think it's the right thing to do.

Stupid nitpick. Use `` backticks for maximum shell compatibility.
Also, the server patch to do this hasn't landed yet, but I think you
knew that. Also, $PKG_CONFIG rather than bare pkg-config since the
user might be overriding it for some reason.

Unfortunately, shell variables won't show up in the autoconf help, so
you might be better to say "default=auto" or "default=from server" or
something like that.

Beware that if the user passed --without-xorg-conf-dir (pretty valid),
you'll end up with XORG_CONF_DIR=no. That obviously would bomb at some
point. It might be better to do a check for server >= 1.8 instead. See
Peter's original evdev patch:

http://lists.x.org/archives/xorg-devel/2010-March/006602.html

I might do this whole section like this:

PKG_CHECK_EXISTS([XSERVER_18], [xorg-server >= 1.7.99],
    [have_server18=yes
    default_configdir=`$PKG_CONFIG --variable=sysconfigdir xorg-server`
    test "x$default_configdir" = x &&
default_configdir="$datadir/share/X11/xorg.conf.d"],
    [have_server18=no])
AC_ARG_WITH([xorg-conf-dir],
    [AC_HELP_STRING([--with-xorg-conf-dir=DIR],
        [Default xorg.conf.d directory [[default=from xorg-server
pkg-config]]])],
    [XORG_CONF_DIR="$withval"
    test "x$XORG_CONF_DIR" = x && XORG_CONF_DIR=no],
    [XORG_CONF_DIR="$default_configdir"])
AM_CONDITIONAL([INSTALL_CONF], [test $have_server18 = yes && test
"x$XORG_CONF_DIR" != xno])

And then use INSTALL_CONF as the conditional in the Makefile.am.

Mostly looks good with the exception of the couple nitpicks. They can
probably get ironed out once in the repo, too.
