  Ubuntu 18.04 Video Crash on Suspend/Hibernate

Status in linux package in Ubuntu:

Bug description:
  After updating to 18.04 when the system automatically
  suspends/hibernates after non-use, the screen goes black, but will not
  wake up by taping the space bar, nor does it display the hibernation
  screen. Additionally, I'm using two screens the laptop and an external
  monitor connected with the Mini Display port. When required to come
  out of suspend, each screen behaves differently. The laptop screen
  flashes while the external monitor may show any of these: 1)
  background screen image with no tool bars or menu; 2) remains black;
  or 3) shows a gray image. The only way to recover is to reboot, either
  by holding the power button or Ctrl-F1 to log back into the system and
  use the reboot command; only the external monitor will recover to a
  terminal screen.

  Upgrading the kernel from 4.15 thru 4.19 does not change the
  suspend/hibernation issue. It seems to be video related issue, since
  HDMI port reacts differently than the Mini Display port, in that
  device settings do not operate the same and changing the settings can
  cause the same type of screen crash. Additionally, trying NVIDIA
  drivers will help with the suspend/hibernation problem and allows the
  hibernation screen to show, but is not a cure. Sometimes the NVIDIA
  drivers will allow it to come back from hibernation and sometimes not.
  My suspicion is that the drivers are not correct for the Intel video

  I am also flummoxed by the fact that I cannot control
  suspend/hibernation. There is no obvious way to keep the system from
  suspending. Screen lock is OFF. Automatic suspend is OFF. Power button
  suspend is OFF. There needs to be more control; the ability to
  eliminate any and all suspend operations is a must! With this type of
  control, I could have kept if from suspending until a fix is
