[TUTORIAL] Installing official NVIDIA driver in Optimus laptop

[Karado]

First, BIG thanks to @TiGER511

I can confirm it works beautifully with Kali 2018.1

One slight issue in my case:

Step #8:

glxinfo | grep -i "direct rendering"

gave me the following:

bash: glxinfo: command not found

Fix:

apt-get install mesa-utils

WORKING beautifully!!!
