Title:
  Kernel Update 3.13.0-22 Deletes Desktop Manager and /etc/X11/xorg.conf
  file

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  I updated from Kernel 3.13.0-20 to 3.13.0-22. After the update my
  computer would only log in to a terminal. I found on the webs how to
  get log files from desktop bootup. The error that was reported was
  missing device section for instance BusID PCI:0@1:0:1.

  After searching the web, I also figured out how to fix the problem,
  which turned out to be the update had removed many of the files needed
  for the desktop to run including the /etc/X11/xorg.conf file. I assume
  the error printout on my question above was due to the missing.conf
  file causing fglrx to fail to initialize properly.

  My first step was to reinstall ubuntu-desktop in the command line
  using sudo apt-get install --reinstall ubuntu-desktop. This was a long
  install. In the middle of the install I was asked to select a desktop
  manager. I selected light-dm. I dont know if that was the right choice
  but I had used that for 12.04, so I figured it would work.

  Than I followed the directions on this website
  http://wiki.cchtml.com/index.php/Ubuntu_Saucy_Installation_Guide#Installing_Catalyst_Manually_.28from_AMD.2FATI.27s_site.29_BETA.2FEXPERIMENTAL
  under the section Generate a new /etc/X11/xorg.conf file. Than I
  forced amd drivers to use that config file. The directions for that
  are also on that website. I than restarted my computer.

  I am hoping the solution to the bug may give a better idea to the
  developers of ubuntu what happened between those kernel updates.
