After routine kernel-update yesterday, today blank screen like KennoVO,
bongos rumbling on start but without video.

After booting with previous kernel I applied the solutions KennoVO
suggested, (2)-(3)-(4) but not (1) as I didn't know what I was doing and
didn't understand how it had to be done. But in the end after reboot it
worked. No errors or other failures.

I must say that while Ubuntu 10 and 12 were simply great, rapid booting,
almost no bugs, this 14.04 has caused me a lot of grievance - slow on boot,
updates that cause more problems than they solve, updates almost every time
I turn on the computer (just like Windows...). Iif I didn't have an allergy
towards Windows I would long have turned my back on Ubuntu. And if You add
to it that Chromium has a sloppy Flash-player that doesn't work half the
times, and the alternative Firefox is pretty slow.
Takes a lot of passion to stick to Ubuntu...

Bug description:
  Filing this against the 340-updates version but possibly the same
  applies to older versions, too. The nvidia source package produces two
  individual dkms packages: nvidia-340-updates, nvidia-340-updates-uvm.
  The problem is that the DKMS build of the nvidia-uvm module runs
  compile steps inside the nvidia modules build directory. This is
  violating the DKMS assumption that each module can be build
  independently (there is no way of describing cross-modules
  dependencies and even more important, the autoinstall step after a new
  kernel is installed will run the modules build in parallel).

  Since nvidia and nvidia-uvm are very dependent on each other the right
  course of action seems to be to combine both sources in one DKMS
  module that produces two kernel modules (this is supported by DKMS).
  For the transition this resulting dkms package needs to have a
  breaks/replaces for the nvidia-uvm package.
