Check "Enabled" for: NVIDIA accelerated graphics driver

After you hit "OK" a bunch of times a few drivers will be installed and you will be told to reboot.

After reboot, I still only had one screen come up. Edit /etc/X11/xorg.conf (back it up first) to look like this:

# If you have edited this file but would like it to be automatically updated
# again, run the following command:
#   sudo dpkg-reconfigure -phigh xserver-xorg
