Evidently the package named "xserver-xfree86-dbg" has a version of X with debugging information compiled in.
I hoped to use it on this report's bug and did $ ln -s /usr/X11R6/bin/XFree86-debug /etc/X11/X Unfortunately, 1.) $ dpkg-reconfigure xserver-xfree86-dbg didn't change /etc/X11/XF86Config-4 and 2.) XFree86-debug aborted with "no screens found" in /var/log/XFree86.0.log when /etc/X11/XF86Config-4 has a "Screen" section. Suggestions welcome.
