I have now performed the BIOS update by following the links provided and the rufus program described at http://ubuntuforums.org/showthread.php?t=2266278&p=13233591#post13233591 For my Gigabyte H81M-DS2V motherboard you press F12 key during the initial power on stages to be given a boot menu. From that menu it should be possible to select a bootable USB device that is connect to the system.
$ sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date Now produces "/dev/mem: No such file or directory". Before it showed the old release details. I entered the BIOS menu and confirmed that the BIOS date is now August 2015. Marking status back to New as requested. I will post an update if I see the problem reproduce. ** Changed in: xorg (Ubuntu) Status: Incomplete => New -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1477631 Title: Xorg crash which returned me to my login screen Status in xorg package in Ubuntu: New Bug description: This looked like the same thing as when Bug #1477574 and Bug #1477566 happened just now. I had Chrome, Terminal & Eclipse open on my Ubuntu PC and was focused on using my laptop via Synergy. In my Synergy setup the Ubuntu PC is the server and the laptop is the client. As in the two bugs I mentioned, the Ubuntu machine seemed to reset back to the login screen. Unlike the last time nothing complained about out of date packages this time. I had not run the upgrade when this bug happened. I have now updated however. Yesterday there was a power cut to this building. I am starting to worry about my hardware integrity. The previous software update I did was at 2015-07-22 08:15:01, some 29 hours before the first time I saw an issue and now I have hit the login screen twice in about 2 hours.
