No proprietary Nvidia driver available on Lenovo W550s

  • 772

I have a Lenovo W550s which contains a 3D Nvidia graphics chip, and I run Ubuntu 15.04 64 bit on it.

The "Additional Drivers" dialog only shows some processor microcode firmware but does not offer a proprietary driver for the Nvidia graphics chip.

lspci reports: "3D controller: NVIDIA Corporation Device 137a (rev a2)"

Is there a way to use the proper driver for full 3D support without resort to hacking?

  1. According to Lenovo website, your graphic card is a NVIDIA Quadro K620M.

    You can install the Nvidia driver using the following PPA :

    sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update 
sudo apt-get install nvidia-355

    Run in terminal

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

    This will install the nvidia-346 driver from official Ubuntu repositories. This driver supports your adapter. It is a long-term-support driver. It should get updates.

    There is nothing fundamentally wrong if you install an Nvidia driver from ppa. It is an unofficial personal repository and a short time supported 355 driver. It may work better or not for you.

    You can test both drivers.
