On Ubuntu 18.04 with kernel 4.15.0-20-generic, I get the following screen when resuming from suspension:

enter image description here

I use default 390 driver for Nvidia shipped with Ubuntu:

[    1.147280] nvidia: loading out-of-tree module taints kernel.

I have the following hardware:

~$ lspci

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.

The location /var/crash/ does not contain anything interesting.

I did not have this issue with previous version of Ubuntu 16.04.


  • what is happening?
  • how do i fix this?

EDIT: I tested Ubuntu 17.10 + kernel 4.13.0-39-generic + nvidia384 + Gnome 3.26.2 and suspension/resume works without issues.
