Issues with NVIDIA GeForce GTX 960 (and others) using Ubuntu Gnome 16.10
It seems there are a number of NVIDIA Graphics Cards that do not place nicely with the Open Source Nouveau driver, some of which is described here.
If you are struggling to install Ubuntu you can edit the Grub launcher options to get it working for the current session.
With the option you want selected (eg
Install Ubuntu) press
nouveau.modeset=0 to the end of the statement that beings with
F10 to resume the boot sequence.
This can also be done once Ubuntu is installed if you are struggling to get to Ubuntu to install the correct packages.
To fix Ubuntu properly you need to install the official NVIDIA Drivers either using
Software & Updates by going to the
Additional Drivers tab.
Or by removing anything that did exist and installing from the ppa. To do this you need to get to a terminal, either over SSH or by accessing another TTY (eg
F1). If neither of these options work use the steps above to add
nouveau.nomodeset=0 on boot.
apt-get purge nvidia-* libcuda-* apt-get purge xserver-xorg-video-nouveau add-apt-repository ppa:xorg-edgers/ppa apt-get update apt-get install nvidia-367 nvidia-settings nvidia-modprobe
Afterwards, reboot and there should be no need to edit Grub on start.
