First I went to the “Additional Drivers” application by accessing Unity and selected this option.
After I just installed Bumblebee and it’s GUI

# Installing bumblebee sudo apt-get install bumblebee bumblebee-nvidia primus linux-headers-generic # Installing bumblebee ui cd ~ git clone http://github.com/Bumblebee-Project/bumblebee-ui.git cd bumblebee-ui sudo ./INSTALL |
Afterwards add /usr/local/bin/bumblebee-indicator to your Startup Applications.
To test to see if it works I run this:

The mesa drivers are the graphics that are run on CPU not GPU. As you can see the NVIDIA card has been detected and is being used.
