I'm going to install Ubuntu 14.04 on my laptop with Intel & Nvidia graphics card. Do I have to install Bumblebee or Nvidia 331.38 has support for optimus. I don't use Nvidia card I would like to use only Intel card due to lower using battery. THX in advance :-)
Battery saving does work, but I didn't notice any change of performance while using nvidia on internal display. I don't have external display so, I don't know what is the outcome.
Also in graphics details, the nvidia device is detected when on performance mode.
Simple instructions what I followed,
