Resume from suspend to RAM fails with nvidia-graphics-drivers-390

[Jaroslaw Ilgiewicz]

After suspending to RAM when resuming only black screen is visible with frozen mouse cursor. Can't switch to console and reset is required. When trying to suspend to RAM with pm-suspend command system doesn't suspend at all, you can find pm-suspend.log file attached. With default nouveau drivers system resumes fine however hangs forever on shutdown.
My specs:
AMD Ryzen 5 1600
Kingston Predator DDR4 8GB
Gigabyte GA-AB350N-Gaming WIFI
MSI GeForce GTX 1060 AERO ITX

I remotely connected with ssh to my frozen desktop and generated dmesg2.log. You can see in this file errors related to GPU.

Status changed to 'Confirmed' because the bug affects multiple users.

I got a workaround for suspend working on Ubuntu 18.04 with a NVIDIA GeForce GTX 1050 Mobile and proprietary nvidia drivers 390. I installed pm-suspend via ```sudo apt-get install pm-utils```. Then, I switch from Gnome Shell to the terminal via Ctrl+Alt+f6. After the login, I do ```sudo pm-suspend```. After waking up from standby, I change back to Gnome Shell via Ctrl+Alt+f1. Done!
