GPU wont work - MarKerR - 01-10-2023

Greetings, good people!

Last time i used hashcat somewhere around 1.5 years ago. And everything worked fine if i remember it correctly.

But few days ago i tried launch benchmark, and hashcat refused to work with GPU. Output are next:
Code:
hashcat (v6.2.5) 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.

Soooo.... in few days i tried couple thing.

Installing CUDA toolkit (as error suggests) from nvidia website turned out as a big failure, because its latest version, which obviously doesn't support 650. Also it for some reason installs latest driver. After this system doesn't load into GUI and shows some messages (see attachment).

Installing CUDA toolkit via
Code:
sudo apt install nvidia-cuda-toolkit
installs 11.5 something version and gives output in which it tells me that:
1) will be installed:
Code:
  libaccinj64-11.5 libcub-dev libcublas11 libcublaslt11 libcudart11.0 libcufft10 libcufftw10 libcuinj64-11.5 libcupti-dev libcupti-doc libcupti11.5 libcurand10 libcusolver11 libcusolvermg11 libcusparse11 libnppc11 libnppial11 libnppicc11 libnppidei11 libnppif11 libnppig11 libnppim11 libnppist11 libnppisu11 libnppitc11 libnpps11 libnvblas11 libnvidia-compute-495 libnvidia-compute-510 libnvidia-ml-dev libnvjpeg11 libnvrtc-builtins11.5 libnvrtc11.2 libnvtoolsext1 libnvvm4 libtbb-dev libtbb12 libtbbmalloc2 libthrust-dev libvdpau-dev node-html5shiv nsight-compute nsight-compute-target nsight-systems nsight-systems-target nvidia-cuda-dev nvidia-cuda-gdb nvidia-cuda-toolkit-doc nvidia-profiler nvidia-visual-profiler
2) will be deleted:     (Why it deletes 470* packages?)
Code:
  libnvidia-compute-470 libnvidia-compute-470:i386 libnvidia-decode-470 libnvidia-decode-470:i386 libnvidia-encode-470 libnvidia-encode-470:i386 nvidia-compute-utils-470 nvidia-driver-470 nvidia-utils-470
3) installed and doesn't need anymore:
Code:
  libnvidia-egl-wayland1 libnvidia-extra-470 libnvidia-fbc1-470 libnvidia-fbc1-470:i386 libnvidia-gl-470 libnvidia-ifr1-470 libnvidia-ifr1-470:i386 libxnvctrl0 nvidia-dkms-470 nvidia-kernel-common-470 nvidia-kernel-source-470 nvidia-prime nvidia-settings screen-resolution-extra
4) recommended package:
Code:
libnvcuvid1
5) suggested packages:
Code:
libtbb-doc libvdpau-doc nodejs

Before installing staff above
Code:
nvidia-smi
gives me

Also i tried to install this, but didn't understood the result:
https://ubuntu.pkgs.org/20.04/cuda-amd64/cuda-compat-11-4_470.161.03-1_amd64.deb.html

Its already too many letters, so i am gonna ask about what bothers me:
1) some suggests that 650 is too old and simply does not going to work, is there a chance that this is true? (but that strange, because only thing that changed over 1.5 years is ubuntu version - 20.04 to 22.04)
2) why cuda also installs drivers in one scenario, and deletes everything that has 470 in name in another?
3) i am pretty sure that i should see built in GPU into CPU as separate device, but where is it?

Any suggestions?

RE: GPU wont work - Snoopy - 01-10-2023

CUDA SDK and Drivers have to fit to each other to work properly, newest sdk will install newest driver by default, so when using legacy driver 470* you have to know which cuda version you need or do some workarounds, see infos for cuda-compat installtions mentioned there
