Install NVIDIA GPU Drivers

Table of Contents

Live boot currently is not supported. The following documentation assumes an installed version of Kali Linux, whether that is a VM or bare-metal.

This document explains how to install NVIDIA GPU drivers and CUDA support, allowing integration with popular penetration testing tools. We will not be using nouveau, being the open-source driver for NVIDIA, instead we will installing the close-source from NVIDIA.

This will cover a dedicated card (desktops users) and optimus (laptops and notebook users).

We recommend that you do not attempt this in a Virtual Machine. It is possible, however its not straight forward, and should only be done if you have a deep understanding of Linux. It is not covered in this guide, as there are too many items to cover for everyone’s environment and setup.

Prerequisites

First, you’ll need to ensure that your NVIDIA card supports CUDA.

GPUs with a CUDA compute capability > 5.0 are recommended, but GPUs with less will still work.


Afterwards, make sure you have contrib & non-free* components are enabled in your network Repositories and that your system is fully up-to-date:

kali@kali:~$ grep "contrib non-free" /etc/apt/sources.list
deb http://http.kali.org/kali kali-rolling main contrib non-free non-free-firmware
kali@kali:~$
kali@kali:~$ sudo apt update
[...]
kali@kali:~$
kali@kali:~$ sudo apt -y full-upgrade -y
[...]
kali@kali:~$
kali@kali:~$ [ -f /var/run/reboot-required ] && sudo reboot -f

Dedicated cards

Let’s determine the exact GPU installed, and check the kernel modules it’s using. Take note, the lspci command contains a unique PCI bus address. Be sure to include the correct address lspci -s XX.XX.X -v:

kali@kali:~$ lspci | grep -i vga
07:00.0 VGA compatible controller: NVIDIA Corporation GP106 [GeForce GTX 1060 6GB] (rev a1)
kali@kali:~$
kali@kali:~$ lspci -s 07:00.0 -v
07:00.0 VGA compatible controller: NVIDIA Corporation GP106 [GeForce GTX 1060 6GB] (rev a1) (prog-if 00 [VGA controller])

        Capabilities: <access denied>
        Kernel driver in use: nouveau
        Kernel modules: nouveau

kali@kali:~$

Optimus cards

For optimus (laptops and notebooks), you will not see NVIDIA for the primary card. You may also not even see NVIDIA listed at all. You can see what the primary card is by doing:

kali@kali:~$ lspci | grep -i vga
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 620 (rev 02)
kali@kali:~$

To detect the NVIDIA card, we need to install nvidia-detect:

kali@kali:~$ sudo apt install -y nvidia-detect
[...]
kali@kali:~$ nvidia-detect
Detected NVIDIA GPUs:
01:00.0 3D controller [0302]: NVIDIA Corporation GM108M [GeForce 940MX] [10de:134d] (rev a2)

Checking card:  NVIDIA Corporation GM108M [GeForce 940MX] (rev a2)
Uh oh. Failed to identify your Debian suite.

kali@kali:~$
kali@kali:~$ lspci -s 01:00.0 -v

        Memory at 80000000 (64-bit, prefetchable) [size=256M]
        Memory at 90000000 (64-bit, prefetchable) [size=32M]
        I/O ports at 5000 [size=128]
        Capabilities: <access denied>
        Kernel driver in use: nouveau
        Kernel modules: nouveau
kali@kali:~$

They nvidia-detect package may fail in places due to Kali being a rolling distribution as it requires a stable release.

Installation

Notice how Kernel driver in use & Kernel modules from lspci are using nouveau, signalling the open-source driver for NVIDIA cards. We are now going to switch to the close-source drivers, and the CUDA toolkit (allowing for tool to take advantage of the GPU).

During installation of the drivers the system created new kernel modules, so its best for to-do a reboot:

kali@kali:~$ sudo apt install -y nvidia-driver nvidia-cuda-toolkit

Dots Per Inch (DPI) & Pixels Per Inch PPI

Upon Kali starting back up, certain things may appear different than what is expected:

  • If certain things are smaller, this could because of HiDPI
  • However, if certain things are larger, this could because the DPI is incorrect

Verify Driver Installation

Now that our system should be ready to go, we need to verify the drivers have been loaded correctly. We can quickly verify this by running the nvidia-smi tool and lspci once again:

kali@kali:~$ nvidia-smi

You can see our hardware has been detected we are using nvidia rather than nouveau drive now!

Hashcat

With the output displaying our driver and GPU correctly, we can now dive into benchmarking (using the CUDA toolkit). Before we get too far ahead, let’s double check to make sure hashcat and CUDA are working together:

kali@kali:~$ sudo apt install -y hashcat
kali@kali:~$
kali@kali:~$ hashcat -I

kali@kali:~$

It appears everything is working, let’s go ahead and run hashcat’s inbuilt benchmark test.

Benchmarking

kali@kali:~$ hashcat -b | uniq
hashcat (v6.0.0) starting in benchmark mode...

Benchmarking uses hand-optimized kernel code by default.
You can use it in your cracking session by setting the -O option.
Note: Using optimized kernel code limits the maximum supported password length.
To disable the optimized kernel code in benchmark mode, use the -w option.

* Device #1: WARNING! Kernel exec timeout is not disabled.
             This may cause "CL_OUT_OF_RESOURCES" or related errors.

There are a multitude of configurations to improve cracking speed, not mentioned in this guide. However, we encourage you to take a look at the hashcat documentation for your specific cases.

Troubleshooting

In the event setup isn’t going as planned, we’ll install clinfo for detailed troubleshooting information:

kali@kali:~$ sudo apt install -y clinfo
kali@kali:~$
kali@kali:~$ clinfo

OpenCL Loaders

It may be necessary to check for additional packages that may be conflicting with our setup. Let’s first check to see what OpenCL Loader we have installed. The NVIDIA OpenCL Loader and the generic OpenCL Loader will both work for our system:

kali@kali:~$ dpkg -l |  grep -i icd
ii  nvidia-egl-icd:amd64                 430.64-5                        amd64        NVIDIA EGL installable client driver (ICD)
ii  nvidia-opencl-icd:amd64              430.64-5                        amd64        NVIDIA OpenCL installable client driver (ICD)
ii  nvidia-vulkan-icd:amd64              430.64-5                        amd64        NVIDIA Vulkan installable client driver (ICD)
ii  ocl-icd-libopencl1:amd64             2.2.12-2                        amd64        Generic OpenCL ICD Loader
ii  ocl-icd-opencl-dev:amd64             2.2.12-2                        amd64        OpenCL development files
kali@kali:~$

If mesa-opencl-icd is installed, we should remove it:

kali@kali:~$ dpkg -l |  grep -i mesa-opencl-icd
ii  mesa-opencl-icd:amd64                19.3.2-1                        amd64        free implementation of the OpenCL API -- ICD runtime
kali@kali:~$
kali@kali:~$ sudo apt remove mesa-opencl-icd
kali@kali:~$

Since we have determined that we have a compatible ICD loader installed, we can easily determine which loader is currently being used:

kali@kali:~$ clinfo | grep -i "icd loader"
ICD loader properties
  ICD loader Name                                 OpenCL ICD Loader
  ICD loader Vendor                               OCL Icd free software
  ICD loader Version                              2.2.12
  ICD loader Profile                              OpenCL 2.2
kali@kali:~$

As expected, our setup is using the open source loader that was installed earlier. Now, let’s get some detailed information about the system.

Querying GPU Information

We’ll use nvidia-smi once again, but with a much more verbose output:

kali@kali:~$ nvidia-smi -i 0 -q

kali@kali:~$

It looks like our GPU is being recognized correctly, so let’s use glxinfo to determine if 3D Rendering is enabled:

kali@kali:~$ sudo apt install -y mesa-utils
kali@kali:~$
kali@kali:~$ glxinfo | grep -i "direct rendering"
direct rendering: Yes
kali@kali:~$

The combination of these tools should assist the troubleshooting process greatly. If you still experience issues, we recommend searching for similar setups and any nuances that may affect your specific system.
