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 :-)

I do have (unfortunately) Optimus technology on my Ntb and I installed 14.04 just yesterday. So far the nvidia card doesn't seem to be working properly, but at least I got some screen through HDMI. Very laggy screen, but at least something since on 13.10 it didn't work at all. –  Jendas Apr 19 at 16:56

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,

  • Open dash by tapping Super (Windows key)
  • Search additional, click on Additional drivers. Following image will open up, By default Nouveau driver will be selected. Select as shown in picture.

    optimus additional driver

  • Again open dash, search nvidia, open nvidia X server settings. Choose intel card as default. Save and logout. See below picture.

After switching to intel and log/out/in; the menu disappeared and I'm unable to recover NVIDIA GPU. sudo prime-select nvidia Error: alternatives are not set up properly Error: nvidia mode can't be enabled –  VictorL Apr 24 at 9:24
    
Hi, I also went ahead and installed 331.38 proprietary, but I cannot switch TO Nvidia GPU GeForce GT 630M. It says it's using intel card, and when I switch, a dialog box with nothing pops up. –  far_sight Apr 28 at 17:35
