get logged off on resume from suspend Nvidia 390 drivers 2nd monitor (18.10)

Question

This is not a problem using only built in laptop screen however when using Nvidia 390 drivers I attach an external monitor and choose

Setting->Display->Single Display

then choose the external monitor to be the only active screen -> then when I suspend upon resume I have gotten logged off which is mentioned in /var/log/auth.log

this issue is repeatable across multiple laptops with Nvidia cards ... issue is only when using nvidia drivers, nouveau drivers are OK no issue

Any ideas/suggestions ?

Here is a clip from /var/log/auth.log look closely at messages just after Lid opened

Looks like it could be gnome-shell ? I booked a ticket https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1806165

I installed the Nvidia drivers by picking from list on Software & Updates -> Additional Drivers ... This scenario is not an issue on 16.04

I found a suggested answer for this problem with newer kernels and gdm, if that is your greeter. See post here:

kernel 4.18.0.11.12 trouble: Video black screen

Make those inserts in /etc/default/grub and run sudo update-grub.

Claim in Nvidia forum is that there's a bug in the kernel that requires this.

2 Here is the one about failing to recover from suspend

I do note that if you use the lightdm display manager, none of this is a problem. Except for stubbornness in wanting to find out why gdm was causing trouble, I have no good reason to try so hard to make it work. And it does work, whether or not with X11 or Wayland (you choose in /etc/gdm/custom.conf).
