[SOLVED]CUDA is not working(disabled)

jojo06 · 2025-12-26 03:26:59

When try to launch GPU related processing it says:

 * OPENCL       disabled
 * CUDA         disabled (/usr/bin/libxmrig-cuda.so: cannot open shared object file: No such file or directory)

CUDA was needed before as well. But as far as I understand, it's a bit problematic, externally.

---
Why do I even need it ?: (beside its unavailable)

I'm testing the mining potential of my graphics card. I'm considering buying graphics cards proportionally and getting into mining. It seems like I have no other way to test it. Or if there is (at least if it's easier than solving the CUDA issue), I can go straight for that.
I've seen a few sites, but they vary greatly depending on the type of crypto and the network. But I still have a script that will calculate profitability (adjusted weekly and monthly).
Additionally, in such cases, the need for CUDA may arise.

Since it's the hardware section, I guess I can ask this too:

Is it possible to earn $500 a month with a $5,000 system?
I can't access it right now, but (maybe a specific model) I was told something like this: it's possible to earn $400-450 per month from mining with 12 (or max 20) of the mentioned graphics cards.
Is this possible ? If not, how many cards do I need to run to earn $500 a month?

You can earn $500/h on a 500$ system - depending how you're using it.

What is "GPU related processing"? libxmrig-cuda.so doesn't seem to be in the repos, looks like it's https://aur.archlinux.org/packages?O=0&K=xmrig ?
Did you rebuild those after your GPU shenanigans?
It's also extremely odd for the program to check /usr/bin for a plugin (but maybe that's an artifact of the debug output and it tests other paths before)

To see whether cuda works: https://wiki.archlinux.org/title/Genera … elopment_3

Also which exact command are you running in order to get that output? Does a basic cuda program work or is it just your miner that is failing?

Yeah I meant mining.
Yes i did reinstall after GPU problem.

What is the output of `pacman -Qi xmrig-cuda`?

seth · 2025-12-27 15:49:41

Spoiler: ¯\_(ツ)_/¯

for pkg in $(pacman -Qsq xmrig); do pacman -Qikk $pkg; done

It's missing and on top of that

Build Date      : Thu 17 Jul 2025 04:51:18 PM +03

from what I can tell xmrig also wasn't rebuilt after the driver shenanigans, but that's likely irrelevant.

Sorry I missed the s in your `pacman` invocation.

You can find multiple online profit calculators for mining requiring only the electricity cost in USD/kWH. Note in many parts of the US GPU mining can not cover the electricity costs no what GPU or number of GPUs is considered, which is why mining rigs sit idle.
