Your specific issue may not be here, but try the solutions described in the answers anyway.
This question is very broad, but each one of these issues likely has one solution.
If you are experiencing a login loop, check the last part of my answer.
If you experience one of the listed issues and have your own solution (mine didn't work, or there's a faster way), feel free to post another POLITE answer, describing your problem and how you fixed it.
Those attempting to install Ubuntu, please refer to the section titled: If you are unable to enter a TTY or are trying to install Ubuntu

Best Answer
Please be aware that this answer may become slightly outdated. I will do my best to update it regularly, but I can't guarantee anything. The driver version used below may not be the latest. Please check the Launchpad page to confirm.
Each of the issues described (and maybe even more) can be fixed by following the steps below.
If you're installing Ubuntu, follow section 3.
1. First make sure you can enter a TTY
Press Ctrl+Alt+F1
If this brings you to a black screen with a login prompt, continue on. Otherwise, you will likely have to boot with a special kernel flag. Instructions are below.
2. Now for the fix
sudo apt-get purge nvidia-*
sudo add-apt-repository ppa:graphics-drivers/ppa
and thensudo apt-get update
.sudo apt-get install nvidia-driver-430
.3. If you are unable to enter a TTY or are trying to install Ubuntu
Ubuntu
option and press E.nouveau.modeset=0
to the end of the line beginning withlinux
.This solution should fix many problems described by users after an upgrade to 16.04. If a fresh install is affected, the solution is the same.
If you run into problems afterward, you should ask a different question. (Refer to this question so that we know it isn't a duplicate.) However, there are a few other small fixes you can try out before you do.
Reinstall Xorg
sudo apt-get purge xorg-* xserver-xorg; sudo apt-get install xorg xserver-xorg; sudo dpkg-reconfigure xorg
.Reinstall your desktop environment
sudo apt-get purge ubuntu-desktop; sudo apt-get install ubuntu-desktop
.sudo apt-get purge ubuntu-gnome-desktop gnome-desktop-environment; sudo apt-get install ubuntu-gnome-desktop
.sudo apt-get purge ubuntu-mate-desktop mate-desktop-environment; sudo apt-get install ubuntu-mate-desktop
Please remember that there are a lot of things that can go wrong, and this is not a guaranteed fix for everything. Even if you are experiencing something listed in the question, the solution may not fully work for you.
This answer is merely for driver issues with 16.04 and nVIDIA. Your issue may go deeper than a bad driver.
