Bug#304108: xserver-xfree86-deb failed

["Kingsley G. Morse Jr." <change@nas.com>]

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.

Thanks,
Kingsley
