Well, this procedure works totally fine on Ubuntu Bare-metal installation. Not exactly the CUDA part, but at least JtR could get the same nvidia RTX A2000 GPU from opencl driver. However, it's not working on WSL2 Ubuntu at all. I tried several times with Windows Nvidia driver installation (guide says WSL2 would not actually need to install nvidia driver like Bare-metal installation), or with actually both Windows Nvidia driver installation along with WSL2 Ubuntu Nvidia-driver-470 installation. Everytime john would only recognize the Intel GPU instead of Nvidia.

May I ask if there's any possibility to do this on WSL2 Ubuntu at all? If yes, which part of me doing wrong please?

Thank you very much. If there's any other information you required, I'm more than happy to keep updating this post.

Cheers,
Channing.

Start with the reported WSL2 Ubuntu environment, the ./configure output, and the ../run/john --list=opencl-devices result. Compare the Windows and bare-metal setup details in the issue, then determine whether John can recognize the Nvidia GPU under WSL2 and document the supported configuration or the missing requirement.
