Bug#299622: Suggested fix doesn't help

[John Winters <john@sinodun.org.uk>]

I have precisely the same problem with "dpkg-reconfigure
xserver-xfree86" not writing /etc/X11/XF86Config-4.  I have tried the
fix suggested by Martin Braure de Calignon but it makes no difference at
all.

There are actually two separate bugs here:

1) That the code silently fails to write the file if the md5sum doesn't
match.  It should at the very least give a message saying that the file
hasn't been written and why.  Better still would be a prompt (like one
gets during an "apt-get upgrade") asking for permission to overwrite the
file.

2) There is some other circumstance - as yet unknown - in which it fails
to write the file.  I can provide an "strace -f" of the process if that
would help.
