>" when I experienced the lockup last nigh the 'Hangcheck .......' error was not anywhere in my syslog, does this mean anything?"

If one does not attach a log from /var/log , or captured through
alternate methods, that contains either a kernel call trace, xorg
backtrace, or at least the hangcheck originally reported, then it's
largely useless unfortunately.

>"Did my dmesg attachment show anything?"

Unfortunately, it did not show any of the three things above. It is not
terribly uncommon for nothing of value to be printed in any of the logs
during a complete system lock. You may have better success capturing
helpful information utilizing the capture methods noted in
https://help.ubuntu.com/community/DebuggingSystemCrash .

>"it mentions building a kernel from scratch, I take it that that is a
requirement to do this?"

Yes.

Title:
  System will periodically lockup with [drm:i915_hangcheck_elapsed]
  *ERROR* Hangcheck timer elapsed... render ring idle

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I have noticed the lockups periodically since 09/13/2014. I can't
  remember what kernel version was in use then possibly kernel
  3.13.0-35-generic or -36. It has continued periodically through
  versions -39; -40 and now to -43.  The last time this has happened was
  today Dec 13 14:40:57 localhost kernel: [154858.820009]
  [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... render
  ring idle. At times when it locks up I will have a cursor on a black
  screen and will have to press the power button to restart other times
  it will lockup whenever I'm in an application such as Firefox or
  Evolution. At that time I can usually CTRL>ALT-F1 log in and run 'sudo
  reboot' to restart the system.
