Installing Bumblebee in Ubuntu 14.04

If you are unfortunate like I, and have an Asus n55sf laptop and want to use your discreet Nvidia graphics adapter, you can't install stock Nvidia driver. You have to install Bumblebee instead. Here is how you can do it painlessly:

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.
