A little lost between NVIDIA and AMD

DadoooR3 · November 5, 2025, 10:21am

Hello,

I am trying to work with NVIDIA CUDA on a machine that has two graphics cards.

The forum gave me some answers, but as I am not very experienced in these matters, I am not sure how to diagnose and find the problem.

The command

prime-select nvidia

followed by a restart does not seem to have any effect.
(I checked with nvtop and NVIDIA-smi, which show me that it is not working.)

I suspect that I haven’t installed everything correctly.

The bug report has been generated, but I can’t find the problem.

D.

P.S. If you know where I can find documentation that will help me understand how to use these graphics cards, I’d love to hear from you

DadoooR3 · November 5, 2025, 3:40pm

After

sudo prime-select nvidia

logoff ; logon

nvtop

Nothing in GPU0 (NVIDIA)
AMD Radeon OK.

nvidia-smi

GPU0 = NVIDIA … OFF

@DadoooR3 Anything suse-prime is deprecated with newer hardware, switcherooctl is what is used…

https://en.opensuse.org/SDB:NVIDIA_Switcheroo_Control

You need to uninstall anything suse-prime, bbswitch, bumblebee related and rebuild initrd dracut -f --regenerate-all

Then you just need to use the AMD for graphics, everything else Prime Render Offload with switcherooctl, it’s integrated into GNOME, just right-click and launch with the discrete GPU.

Thank you for your reply.

After executing the following commands:
sudo zypper remove suse-prime
sudo zypper al suse-prime
sudo dracut -f --regenerate-all

I restarted the machine.

sudo systemctl status switcheroo-control.service
gives:

and
switcherooctl list

gives:

I attempted to produce a calculation requiring CUDA (a Python script calling OPENCV and torch) with the command:

switcherooctl launch -g 1 python OCR_openCV_2.py

Unfortunately, it doesn’t seem to work.

Any ideas?

…double post removed…

By the way, you have the completely wrong driver installed for the Nvidia card…
Why do you want to use the incompatible v470 driver for your RTX 3080?

You need the G06 aka v580 driver series.

Show zypper se -si nvidia and zypper lr -d.

DadoooR3 · November 5, 2025, 7:46pm

Thank you for your analysis.

I was surprised to see the G05 drivers installed (I recently reinstalled my machine).
I simply let the installer do its job.

zypper se -si nvidia

zypper lr -d

The question remains: how should I proceed?

DadoooR3 · November 6, 2025, 6:07am

I tried this:

Uninstalls with Yast:

nvidia-computeG05
nvidia-computeG05-32bit
nvidia-gfxG05-kmp-default
nvidia-glG05
nvidia-glG05-32bit
X11-video-nvidiaG05
X11-video-nvidiaG05-32bit

New installation with Yast:

nvidia-computeG06
nvidia-gfxG06-kmp-default
nvidia-glG06
X11-video-nvidiaG06

Which gives me, with dependencies

then

sudo dracut -f --regenerate-all

Reboot

Enroll MOK (secureboot)

and, to test:

nvidia-smi

Without success.

Finally with:
