I am using Ubuntu 14.04.1 for sometime. It uses my Intel HD 4000 graphics in my Laptop, but I want it to use y Nvidia GT 740m graphics card to. I have the nouveau driver for Nvidia, but it seems like its not using it.

lspci -v | grep VGA yields 

00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 09) (prog-if 00 [VGA controller])

And also Ubuntu is able to recognize the Nvidia graphics card

What should I do to use my Nvidia graphics card in Ubuntu. Previously I tried using Bumblebee but it screwed up my laptop. Should I go for the proprietary drivers that Ubuntu's additional driver provides ?

Thank You

Here is what worked for me to activate my Nvidia card (I put all the steps even if you have done some already) :

  1. Remove all old Nvidia & Nvidia related packages :

    sudo apt-get purge libvdpau-va-gl1 bumblebee* nvidia*

  2. Install Nvidia driver :

    sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update 
sudo apt-get install nvidia-352

  3. Open Nvidia X Server Settings, go in PRIME Profiles and select Nvidia (High Performance Mode)

You can also install prime-indicator that will let you quickly switch between your Intel HD 4000 graphics and your Nvidia GT 740m card :

sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install prime-indicator

  • I installed Nvidia X server settings as you said, but it does't have any prime profiles. – Abhi80 Sep 17 '15 at 13:07
  • Something weird happened. I locked my account, and went to have my lunch. Came back and my keyboard won't work. So I restarted my laptop, and booted into Ubuntu. A message popped up that "Your system is low on graphics card" I pressed OK and it rendered me into the default tty. Then I uninstalled nvidia-355 and again rebooted my laptop. Now its working fine. – Abhi80 Sep 17 '15 at 13:20
  • Why won't ubuntu work with Nvidia ? :-( – Abhi80 Sep 17 '15 at 13:21
  • Really? thats weird. Try the updated answer please. – hg8 Sep 17 '15 at 15:03
