[Risolto] - Ubuntu Mate 18.04 - Risoluzione e scheda grafica nvidia in tilt

[Andrea]

chiedo scusa, ma sono costretto a premere il bottone dell'alimentazione per arrestare il pc.

Ho provato anche a reinstallare  ubuntu-mate-desktop, con:

Codice:

sudo apt purge ubuntu-mate-desktop

e poi con

Codice:

sudo apt install --reinstall  ubuntu-mate-desktop

quindi con

Codice:

sudo apt update

ma si blocca sempre allo spegnimento.

Se può servire, questo è il mio file di grub:

Codice PHP:

<?php 

# If you change this file, run 'update-grub' afterwards to update

# /boot/grub/grub.cfg.
