How to set up nVidia Optimus/Bumblebee in 14.04

The previous methods i have used to set up Bumblebee on 13.10 based distributions is not working under Ubuntu 14.04 . How can I set up Bumblebee and Bumblebee GUI in Ubuntu 14.04 ?

To install bumblebee in Ubuntu 14.04, run these commands in terminal

sudo apt-get install bumblebee bumblebee-nvidia primus nvidia-331

Now you have to install Bumblebee GUI to manage apps to be opened using nVidia. Here is the instructions:

Install Python App Indicator:

sudo apt-get install python-appindicator

Install Git:

sudo apt-get install git

Make a directory for git:

mkdir git && cd git

Check out the repository:

git clone https://github.com/Bumblebee-Project/bumblebee-ui.git
cd bumblebee-ui
sudo ./INSTALL

Go to Startup Applications and add bumblebee-indicator

Now reboot.
