Install nvidia *.run driver

Newly installed linuxMint system, nouveau driver conflicts nvidia driver when I was trying to install the later. To disable the nouveau, do following:

Install Nvidia Drivers in Ubuntu 15.04

Lets remove first everything that point to any existing nvidia installation.

open a terminal (ctrr+alt+t) and type:

sudo apt-get remove nvidia*

sudo apt-get autoremove

update and download a few tools that we will need:

sudo apt-get update

sudo apt-get install dkms build-essential linux-headers-generic

Now its time to blacklist the nouveau driver.

sudo nano /etc/modprobe.d/blacklist-nouveau.conf

and add the following lines:

blacklist nouveau
blacklist lbm-nouveau
options nouveau modeset=0
alias nouveau off
alias lbm-nouveau off

Blacklist the modules. Open the blacklist.conf file.

sudo vim /etc/modprobe.d/blacklist.conf

add the following modules in the file.

blacklist amd76x_edac #this might not be required for x86 32 bit users.
blacklist vga16fb
blacklist nouveau
blacklist rivafb
blacklist nvidiafb
blacklist rivatv

Disable the Kernel nouveau by typing the following commands:

echo options nouveau modeset=0 | sudo tee -a /etc/modprobe.d/nouveau-kms.conf

update-initramfs -u

Now go to nvidia.com and download the driver for your graphic card.
