(Guide) Installing Nvidia + Bumblebee + CUDA for Optimus enabled Laptops

Thanks for pointing out the files, apprantly I don't know how to use the command 'locate'.
I have completed the install now, without error. I guess maybe I am not in the know for how NVIDIA Gforce is used. Under Applications -> System Tools -> Preferences -> NVIDIA X server settings I have the below error.

You do not appear to be using the NVIDIA X driver.  Please edit your X configuration file (just run `nvidia-xconfig` as root), and restart the X server.

Applications -> System Tools -> Preferences -> Systems Settings -> Details -> Graphics (there is no driver listed and Experience states "Fallback)

Applications -> Programming -> Nvidia Visual Profiler (not sure what this is all about, it appears to be a web page)

I guess I am confused as to what getting the NVIDIA drivers installed correctly was supposed to accomplish.

The reason it is giving you an NVIDIA X driver error is because it's not loaded (the driver) unless you call it with optirun. This is a power saving feature and the entire reason we install bumblebee.

try the command below:

 
optirun glxspheres64

You should see a pretty window appear and terminal will be printing some FPS for you. That means the driver install worked.

If you want to use the NVIDIA card (such as in a graphics demanding application), prefix the command with optirun.

Say I wanted to run cudahashcat i would use the command

 
optirun cudahashcat

Hi everyone. Please help. I followed the guide from post 25 step by step till Cuda install, everything works well, no error but when i try to see if it works what have I done with optirun glxspheres64, i got 2 errors

[ 1465.806859] [ERROR]Cannot access secondary GPU - error: [XORG] (EE) No devices detected.

[ 1465.806942] [ERROR]Aborting because fallback start is disabled.

and for primusrun glxgears
Xlib: extension "GLX" missing on display ":0.0".
Error: couldn't get an RGB, Double-buffered visual

In xorg.conf.nvidia I have:

Section "ServerLayout"
Identifier "Layout0"
Option "AutoAddDevices" "false"
Option "AutoAddGPU" "false"
EndSection

Section "Device"
Identifier "DiscreteNvidia"
Driver "nvidia"
VendorName "NVIDIA Corporation"
BusID "PCI:01:00.0"
Option "NoLogo" "true"
Option "UseEDID" "false"
Option "UseDisplayDevice" "none"
EndSection

in bumblebee.conf i changed only line 22 "Driver=nvidia"

lspci | grep 3D comand give me as a result 01:00.0 3D controller: NVIDIA Corporation Device 1292 (rev a1)

I use Nvidia 740M in an asus laptop, I just installed kali and updated&upgraded without any error after I tried to install from first post and I got
root@kali:~# modprobe nvidia-uvm
ERROR: could not insert 'nvidia_uvm': No such device but optirun glxspheres64 it worked that time.
but that time i installed and uninstalled too many times and I haven't any ideea how to solve and it was too much mess around.
Any help appreciated. Thank you in advance

@2code

Edit xorg.conf.nvidia and adjust the line:

BusID "PCI:01:00.0"

To read

BusID "PCI:01:00:0"

And restart bumblebeed
