I'd like to perform a kernel bisect to figure out which commit caused
this regression. We need to identify the earliest kernel that did not
exhibit the bug and the first kernel that did exhibit the bug.

Can you test the following kernels and post back?

v4.4 final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4-wily/
If v4.4 final exhibits the bug, we should move on to testing some of the v4.4 release candidates. 

v4.4-rc4: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4-rc4-wily/

If v4.4-rc4 does not exhibit the bug then test v4.4-rc6:
v4.4-rc6: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4-rc6-wily/

If v4.4-rc4 does exhibit the bug then test v4.4-rc2:
v4.4-rc2: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4-rc2-wily/


If all of the 4.4 kernels do in fact have the bug, then we should test the 4.3 final kernel.  It is available from:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.3-wily/


Thanks in advance!

Title:
  Kernel 4.4x results in blackscreen - Intel Ivybridge

Status in linux package in Ubuntu:
  In Progress
Status in linux source package in Xenial:
  In Progress

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.
