How to install Nvidia Geforce 750M driver on KAli linux 2.0?

Question

linux

I know that similar questions were asked several times here, but I did not find an answer in them, so I am writing now.
The problem is that I have several video cards on my laptop. The
first one that works with Linux now is the "Intel® Haswell Mobile" processor graphics
. from this site And according to the instructions from this site , after rebooting, I get a sad black smiley on a white screen and I have to reinstall Linux. Also in the first case when the black screen I press "CTRL + ALT + F1" I enter there "[email protected]:~# rm /etc/X11/xorg.
[email protected]:~# reboot" to delete the "xorg.conf" file, I press "ENTER" and nothing happens,
and how can I find this "xorg.conf" file on the laptop?

Answer 1

I don’t know how it is on Kali, but under Arch the drivers for Intel graphics come out of the box (mesa), for nvidia I download (but they are inactive, because "the main one is intel"), after which bumblebee / nvidia prime is installed to work with discrete card.
PS Nvidia Optimus is not a video card, it is a power saving technology by using two video cards)
