Hi.
I have a Lenovo Legion Pro 7 (16ARX8H) with a Ryzen 9 7945HX and an RTX4090.
I have followed this guide to install the NVIDIA drivers. I only went as far as step 7, because I don’t want to have my NVIDIA GPU as the primary GPU.
lspci shows my NVIDIA GPU under the name GN21-X11, which does not seem right to me. neofetch also displays the same weird name.
$ lspci | grep -e VGA
01:00.0 VGA compatible controller: NVIDIA Corporation GN21-X11 (rev a1)
05:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Raphael (rev d8)
$ lspci | grep -e 3D
nvidia-smi however, displays the GPU correctly:
$ nvidia-smi

If I try to use the GPU with hashcat, it gives me some errors, but it does correctly recognize the model.
$ hashcat -b
