I have DELL inspirion laptop and i have both integrated and non-integrated nvidia 340 series graphics card. When I open additional drivers tab and i have 3 options :

  • use NVIDIA binary driver - version 340.76 (proprietary, tested)
  • using X.Org X server - Nouveau display driver from xserver-xorg-video-nouveau (open source)
  • use NVIDIA binary driver - version 340.76 (proprietary)

Should I leave settings like this or change something (to improve graphics quality )?

Edit

Output for lspci command

00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 0b)

  • You can install a proprietary one. It does not matter which. – Pilot6 Aug 19 '15 at 12:38
  • well, when I look at my SYstem settings i get Graphics: Intel® Haswell Mobile and i think thats the integrated video card – David Marjanovic Aug 19 '15 at 12:41
  • Please edit your question and add output of lspci -k | grep -EA2 'VGA|3D' terminal command. – Pilot6 Aug 19 '15 at 12:42

You can install proprietary drivers by running in a terminal:

sudo apt-get update
sudo apt-get install nvidia-346 nvidia-prime

Then you will be able to switch between the integrated and discrete adapters after a reboot.
