[TUTORIAL] Installing official NVIDIA driver in Optimus laptop

[tmoran1116]

I'm having some difficulty installing the driver and wonder if anybody could help me.
I've got an ASUS Q551LN.
It has a hybrid video setup with Intel 4400 combined with NVidia GT 840M graphics cards.


For the life of me I can't get the NVidia driver working.
Following the steps listed here:
1) I've verified that both cards are seen by running lspci ....
2) I've blackisted nouveau and updated initramfs and verified that the module is not loaded.
4) I've tried installing the driver via apt get and running the installed downloader from NVidia (fresh separate installs).
5) Running: nvidia-xconfig --query-gpu-info
I get an error stating that it cannot query the gpu--it is present in lspci
6) There is also no xorg.conf file

When I reboot the laptop it starts with some text (something about mount, not video related) on top of the screen and the text will change color.
I could open another terminal by using alt-ctrl-f2.

My other info:
Kali 2017 was up to date in all attempts to get this working.
The laptop is touch screen, but that doesn't seem to be an issue.
The laptop is UEFI, and I have to use UEFI as the BIOS has almost no options that could be changed by the user.
As an aside note, the laptop boots very quickly.
I can't change any graphics options in the BIOS other than memory allocation.

Does anybody have any suggestions?

Thanks in advance.

You can always change your UEFI boot to legacy boot from bios.You should have something called "Enable CSM" in your bios which enables legacy boot.The error seems like your GPU is not powered on for some reason as it can not query the gpu.Try reinstalling kali in legacy bios mode.

There will not be any xorg.conf file by default.you have to create it as i've stated in my post.
