Manual NVIDIA binary driver package install
Install the NVIDIA binary driver package manually. It will automatically blacklist the Nouveau default driver and make the kernel modules for you:
sudo apt-get install nvidia-current
Then simply modify your "xorg.conf" to use it. Copy and paste the whole code snippet in the terminal where you ran "sudo -i":
echo 'Section "Screen"
Identifier "Default Screen"
Identifier "Default Device"
Option "NoLogo" "True"
' > /etc/X11/xorg.conf
Then reboot your machine.
In case it doesn't work, you can get back to the default state by reverting the changes:
sudo rm /etc/X11/xorg.conf && sudo apt-get purge nvidia-current nvidia-settings
And of course then you need to reboot.
