nvidia driver install for ubuntu 14.04 using xorg-edgers ppa

Question

Graphics card: Nvidia GT740
OS: ubuntu 14.04 64bit

I tried to install nvidia driver in the following way:

sudo add-apt-repository ppa:xorg-edgers/ppa
sudo apt-get update
ubuntu-drivers devices | grep recommended gives:

driver   : nvidia-340 - third-party free recommended

Then I intend to do:

sudo apt-get install nvidia-340

My question is do I have to do:

sudo apt-get --purge remove xserver-xorg-video-nouveau before i install nvidia-340

Do I have to blacklist anything?

Answer 1

By default you shouldnt need to remove nouveau grafics but if you have any type of conflict remove it, i generally just download then and install them and it works fine.
