Title:
Ubuntu 18.04 Video Crash on Suspend/Hibernate

Status in linux package in Ubuntu:
Confirmed

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
card.

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
generated.
