Title:
  why is my /etc/X11/xorg.conf continually being removed?

Status in ubuntu-release-upgrader package in Ubuntu:
  Confirmed

Bug description:
  Please could anyone suggest how to prevent whatever ubuntu 14.04.2 x86_64 upgrade / drivers package is removing 
  my /etc/X11/xorg.conf file from removing it,  or what this component might be .

  Everytime this happens, which appears to be triggered by the periodic package management update check ,
  I lose my second monitor, and have to reboot .

  My system is a fully up-to-date ubuntu 14.04.2 x86_64 8-core Haswell
  system with 16GB RAM and a 1TB hard disk.

  The applications which were displaying on my second monitor remain running, but as I can never
  access the screen on which they were displayed until rebooting, this problem has resulted in
  me losing some work in those applications before I could save what I was working on.

  This problem started happening a few weeks ago with an xorg system related upgrade - but would
  it be the xserver or some driver's package scripts that are doing this ?

  There is nothing in the syslog about replacement of xorg.conf .  This
  fact in itself is a bug .

  I have maintained this xorg.conf file in /etc/X11/xorg.conf , and I have a link to it as
  /usr/share/X11/xorg.conf.d/000-screens.conf :

  What could be so objectionable about this file to which Ubuntu component's package scripts ?

  Anyway, when it happens, the only way to regain my second screen is to
  reboot .

  What a time waster !

  At least the xorg.conf is backed up to /etc/X11/xorg.conf.MMDDYYYY .

  But it a pain to have to reboot to regain the second screen , especially as your
  boot scripts are unable to fsck the root filesystem ,  and so each time I reboot
  I must go into recovery mode, fsck the filesystems, and poweroff, because if I don't
  poweroff after rebooting into recovery mode, I get X-windows.  Gee, what a "trusty" operating system!

  I have done, as root:
    $ chmod a-w /etc/X11/ /etc/X11/*
  meaning that even the root user can't remove files in
  that directory without being prompted, but still something is removing
  that file.

  Does anyone have any idea what virus-like entity might be removing my
  file ?
