How to check if nVidia driver installed correctly Ubuntu 18.04

Question

I have installed nvidia driver on Ubuntu 18.04 as described in this link, but my laptop gets overheated sometimes.

How can I make sure drivers are installed successfully and correctly in Ubuntu?

Solution 1

The best way to do this is to open up your terminal and run the following command:

nvidia-settings

This will show you settings about your NVIDIA Driver as well as your X Server Information and will even allow you to change certain options like power saving mode.

Solution 2

You could check the terminal with this command:

sudo apt-cache policy nvidia-340

In the return you see the word installed.
