Public bug reported:
I was able to fix it by manually updating to kernel 3.13.0-20-generic.
linux-headers-3.13.0-20 & linux-headers-3.13.0-20-generic was required
to resolve the issue.
What I expected to happen? Updating Ubuntu 14.04 LTS would not break my
video drivers, preventing me from accessing my system without entering
into recovery mode.
What actually happened? Updated to Ubuntu 14.04 LTS, video drivers broke
in an irrecoverable manner causing a black screen upon completion of
booting, updated kernel and re-built the nvidia drivers.
