Ok, since we keep running into this second bug, it would probably be
better to bisect the Ubuntu kernels, versus the Upstream ones.  There
may be a fix in Ubuntu that prevents this second bug.

To do that, we also need to find the last good Ubuntu kenrel and the
first bad one.  The last 4.2 based kernel before a fork to 4.3 for
Xenial was: 4.2.0-16.19

The first kernel based on v4.3-rc1 was: 4.3.0-0.9, so we should be able
to bisect between those two.

Can you first test the following two kernels and confirm 4.2.0-16.19 is good 
and 4.3.0-0.9 is bad.
4.2.0-16.19: 
https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/ppa/+build/8287818
4.3.0-0.9: https://launchpad.net/ubuntu/+source/linux/4.3.0-0.9/+build/8360668

NOTE: With both these kernels, you have to install both the linux-image
and linux-image-extra .deb packages.

Title:
  Kernels 4.3-4.8 result in blackscreen - Intel Ivybridge

Bug description:
  When I install Ubuntu 16.04 on my computer the screen goes blank at
  login. I can blindly login and it boots but I cannot use the display
  (external monitor through HDMI).

  I've looked online for an answer to this issue but could not find a
  solution.  However, many people report this issue in forums with the
  4.4x kernel.

  On my main computer, I upgraded from 14.04 to 16.04.1. On this
  computer I was able to switch back to the 3.13 kernel which *does
  work*.

  On the same computer, if I use a 16.04 live CD, it does the same
  thing.  The screen goes blank.

  UEFI may be part of the issue as well.  I have it disabled in bios
  (set to legacy mode) but when I first boot, it seems to go into UEFI
  mode first and then, after rebooting with <ctrl><alt><delete> it shows
  me the list of kernels. I can select the kernel from there but if I
  use a 4.4x kernel, it blanks out at encryption passphrase screen.

  There are also people with similar issues on AskUbuntu.

  Here's some basic HW info.  If you require more, please ask.
