解決方案： How to Install Latest Nvidia Drivers on Ubuntu

First start by adding the Proprietary GPU Drivers PPA to your system package sources and update your system package cache using apt command.

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

Then install the latest stable nvidia graphics (which is nvidia-387 at the time of writing this article) using the following command.

$ sudo apt install nvidia-387           

Alternatively, open Software & Updates under System Settings and go to Additional Drivers tab, select the required driver version and click “Apply Changes”.

Next, reboot your computer for the new driver to start working. Then use the lsmod command to check your installation status with the following command.

It will list all currently loaded kernel modules in Linux, then filter only nvidia using grep command.

$ lsmod | grep nvidia            

Some times updates do not work well as expected. If you face any issues with the latest drivers installation such as black screen on startup, you can remove it as follows.

$ sudo apt-get purge nvidia*           

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