Ubuntu 18.04 with kernel
4.15.0-20-generic, I get the following screen when resuming from suspension:
I use default
390 driver for
Nvidia shipped with Ubuntu:

I have the following hardware:

After the fuzzy screen appears, I can change volume with keyboard bindings and move the mouse around, but pretty much anything else doesn't work, so I have to reboot the system manually.
/var/crash/ does not contain anything interesting.
I did not have this issue with previous version of Ubuntu
- what is happening?
- how do i fix this?
EDIT: I tested
Ubuntu 17.10 +
kernel 4.13.0-39-generic +
Gnome 3.26.2 and suspension/resume works without issues.
