Honestly, more than a year ago nVidia drivers were absolutely nightmarish. It used to be such a frequent issue that I stopped updates for nVidia drivers until I could take a full system backup. Btrfs has been a game changer, allowing backups to automatically happen on updates and allowing you to boot into a previous state. And given the level of Linux growth through Steam/Valve pushing it nVidia seems to have been trying harder. Only one update issue this year so far and it was a simple roll back, make a change, apply updates again.
