Ubuntu 18.04 LTS on Macbook pro 11,3

When pausing with the Gnome alt+shutdown button, or entering command sudo pm-hibernate, screen becomes black but the machine is not completely turned off. Pressing a button after a while may display the mouse arrow or Ubuntu Gnome desktop but it is frozen. sudo hibernate is quite similar leaving a message on black screen saying s2disk is writing image but it never finishes. I can input characters though. With sudo s2disk I get black screen but machine is not shutdown. In any cases the machine won't completely turn off and I have to hard shutdown.

I have also tried with the proprietary driver of nVidia, no change.

Swap partition is active and bigger than the 16GB ram. Could this issue be related to hardware, although I have no problem with suspending to disk from Windows or MacOS on the same machine ?

I would appreciate any help to solve this situation.
