There is no evidence in the logs that there was a GPU lockup event (the
prototypical X freeze with -intel graphics).  Just the vblank counter
failure errors in the log.  I assume those messages correspond to when
the system became unresponsive?

You indicated this happens multiple times per day under certain
circumstances.  Do you know a specific activity that tends to trigger it
more often than others?

Looking at your dpkg.log file, it doesn't look like any X packages
upgraded recently, but perhaps some other package changed and is
triggering it.  Most of the packages appear to have received only minor
version bumps, but I see unity moved from 4.20 to 4.22.  Are you able to
reproduce this bug with unity-2d (or gnome classic desktop)?  If not,
you might try seeing if downgrading to an earlier unity version also
prevents the issue (apt-get install unity=4.20.0-0ubuntu2 perhaps)

Other than that, do you happen to know which day you first noticed these
lockups?  That would help narrow down what package might be at fault.
