dpkg-reconfigure won't change it if you've modified it.  It compares the
current md5sum against a stored md5sum of the original config file.  If the
two are different, it will go through the whole configuration script and
then *silently fail* to update the file.  This is a longstanding bug-- see
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=223929 .

To make dpkg-reconfigure think that xorg.conf hasn't been modified, run

md5sum /etc/X11/xorg.conf >| /var/lib/x11/xorg.conf.md5sum

then rerun dpkg-reconfigure xserver-xorg.
