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. John Winters -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
