R Robinson, the next step is to fully reverse commit bisect from kernel
3.13 to 4.6-rc6 in order to identify the last bad commit, followed
immediately by the first good one. Once this good commit has been
identified, it may be reviewed for backporting. Could you please do this
following
https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F
?

Please note, finding adjacent kernel versions is not fully commit
bisecting.

After the fix commit (not kernel version) has been identified, then
please mark this report Status Confirmed.

Thank you for your understanding.

Title:
  Blank laptop screen

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Since the upgrade to 3.13.0-85-generic, my laptop screen is blank from
  when I would normally see the 'Kubuntu' logo at boot time onwards. An
  external monitor still works OK. I can see that the laptop backlight
  is on but the display is black.

  If I select 3.13.0-83-generic from the grub menu, everything works OK.
