If everything you need works fine with the open-source driver, then you don't have to install the proprietary driver.

Or, if you're

  • Using a laptop with hybrid-video config (Intel + nVidia).
  • Want to reduce the power consumption by using the Intel GPU.

You can install the proprietary driver, which will allow you to choose which GPU to use (between Performance Mode and Power Saving Mode).

  • Yes, i want to install proprietary driver but i don't know what one should i choose in Additional Drivers. now i use X.Org X server - Nouveau display driver from xserver-xorg-video-nouveau ( open source ). – Crossing Oct 08 '14 at 05:23
  • Other than that is ok, I think it's nvidia-331 – P.-H. Lin Oct 08 '14 at 06:12
  • i found 2 drivers [ NVIDIA binary driver - version 331.89 from vnidia-331 (open source) and NVIDIA binary driver - version 331.38 from nvidia-331-updates ( proprietary) ]. i choose nvidia-331-updates (proprietary) > Apply Changes and close. i open it again and see but driver isn't change. why and how to change it? – Crossing Oct 08 '14 at 10:20
  • You will need Internet connection to download the driver, after you hit "Apply Changes", it should start installing sequence. If not, try sudo apt-get install nvidia-331-updates in your terminal (Ctrl+Alt+t) – P.-H. Lin Oct 08 '14 at 10:30
