Install NVIDIA Drivers Last Stable Release (long-lived branch) for Ubuntu 13.10

ubuntu13.10-last-nvidia-drivers

1. Since we are using NVIDIA driver, we need to remove or disable XServer Nouveau Drivers
* Disable :
** sudo nano /etc/modprobe.d/blacklist-nouveau.conf
** Add the following two lines :
blacklist nouveau
options nouveau modeset=0
* Remove : sudo apt-get remove xserver-xorg-video-nouveau

2. Stop the display manager : sudo service lightdm stop
3. Install the drivers :
    sudo apt-get install nvidia-prime
    sudo add-apt-repository ppa:xorg-edgers/ppa
    sudo apt-get update
    sudo apt-get install nvidia-331
4. Check the file /etc/X11/xorg.conf and make sure the X Config "UseDisplayDevice" is commented
4. Reboot : sudo reboot

Result : everything should work as expected.
