Optimus install problems.

[xNotta]

I've been trying to get Kali and my laptop (with an Nvidia Optimus GPU) to work together but I can not figure it out.

I have Kali 64bit installed on a partition and dual booted with Windows.

List of guides I have tried:
These ones seem the most promising and they are the ones that I am currently using:

I have also tried the ".run" files from nvidia and the ".run" for CUDA.

I installed the latest drivers using "apt-get install nvidia-drivers" (Nvidia meta file, installes everything) and I installed bumblebee using "apt-get install bumblebee" and "apt-get install bumblebee-nvidia."

If I configure xorg.conf, I go to the terminal that happens when gdm3 isn't running and can't "service gdm3 start"

Bumblebee gives this error when I try something like:

root@kali:~# optirun pyrit list_cores

[   52.047678] [ERROR]Cannot access secondary GPU - error: Could not load GPU driver

[   52.047736] [ERROR]Aborting because fallback start is disabled.

Can someone please help me get my optimus gpu working please?
