1. Add the NVIDIA GPU driver PPA to your system:

   Open a terminal window by pressing Ctrl + Alt + T keys on the keyboard.

   Add the graphics-driver PPA:

   sudo add-apt-repository ppa:graphics-drivers/ppa
   

   This will provide info on the current long-lived branch release: `nvidia-xxx`

   sudo apt update
   sudo apt install nvidia-driver-xxx
   

   Ubuntu 18.04

   sudo apt update
   sudo apt install nvidia-driver-xxx
   

   Ubuntu 16.04

   Support for Ubuntu 16.04 is removed since SDK 2.7. To see Ubuntu 16.04 instructions for an earlier SDK version, change the Knowledge Base version in the top left corner.

   After installing the driver, restart your system:

   sudo reboot
