Hashcat doesn't detect GPU on Linux (Debian)

[Aadniz]

Hi.

I just installed Hashcat (v5.1.0) and it doesn't detect the GPU.

This is the output of ./hashcat64.bin -I

OpenCL Info:

Platform ID #1
  Vendor  : Intel(R) Corporation
  Name    : Intel(R) CPU Runtime for OpenCL(TM) Applications
  Version : OpenCL 2.1 LINUX

  Device ID #1
    Type           : CPU
    Vendor ID      : 8
    Vendor         : Intel(R) Corporation
    Name           : AMD Ryzen 5 1600 Six-Core Processor
    Version        : OpenCL 2.1 (Build 0)
    Processor(s)   : 12
    Clock          : 0
    Memory         : 8046/32187 MB allocatable
    OpenCL Version : OpenCL C 2.0 
    Driver Version : 18.1.0.0920

I'm using Nvidia GeForce GTX 1080 Ti with driver version 390.116
I would prefer to not mess too much with the Nvidia drivers, as I'm using 4 monitors where 2 of them are 165 hz

Does anyone knows what the issue is?
Do I need to install some Nvidia dependencies?

please try to run the "clinfo" command line tool. if that external command lists your GPUs, we should investigate this further.
My educated guess is that not even an external minimal tool like clinfo lists your GPUs and therefore it's a setup/installation problem (not a hashcat bug etc).

I think questions like this should be asked in the hashcat forum (https://hashcat.net/forum) instead, because this is more like a user question (not a crash/bug/feature request etc).

Alright, so I can't find the GPU with the "clinfo" command and believe the issue is not related to hashcat.

It would be great if you would help me out here

I would suggest to start from here: https://hashcat.net/faq/wrongdriver
then you should also try to run "hashcat -b" and see if the device, driver and OpenCL ICD loader are detected/installed correctly.

I think we can/should close this issue, because there are many similar solved questions on the forum (and even closed issues on this github issue tracker).

A 1080 ti should definitely work, but there could be many reasons why it's not working yet (including xorg configuration problems, additional GPU on motherboard and dedicated GPU is disabled in BIOS/UEFI, driver install problems, mesa/pocl problems, ...)

Fixed by updating Nvidia driver.

When I posted this, I used an old Nvidia driver NVIDIA 390.116
Now I have NVIDIA 430.40 and it works!
