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

[Zach Kraus]

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.

The source package I think is the kernel update which I could not find in the package list. When the kernel was updated about 50 to 200 packages were updated/downloaded as well so its hard to know the specific package in this case. If anybody knows which package to select for this please do so.
