[Ubuntu20.04] nvidia-smi detects no devices (using driver 530)

[rothanton.hhb]

Our IT told us to update the graphics drivers due to newly discovered vulnerabilities, and after doing

sudo apt remove nvidia*
sudo apt autoremove
sudo apt install nvidia-drivers-530

afterwards, nvidia-smi tells us that there are no devices to be found.
I tried both nvidia-drivers-530 and -open, neither worked with this issue.

It used to work with -470

Edits:

I noticed via

cat /proc/driver/nvidia/version

that I had installed the open driver:

NVRM version: NVIDIA UNIX Open Kernel Module for x86_64 530.41.03 Release Build (dvs-builder@U16-T02-35-3) Thu Mar 16 19:33:35 UTC 2023
GCC version: gcc version 9.4.0 (Ubuntu 9.4.0-1ubuntu1~20.04.1)

Though no matter how, if I did

apt install nvidia-driver-530

it always would install the open driver, so the question is, why does it do that, and how can I install the closed source driver?

Please use Software & Updates to switch to the non “-open” driver version.

And how do I do that without the GUI? I have no graphical interface available on this system, I am just connecting via ssh

Don’t know, if I run
sudo apt install --dry-run nvidia-driver-530
I get the closed driver

Inst nvidia-kernel-source-530
Inst nvidia-dkms-530

with
sudo apt install --dry-run nvidia-driver-530-open
the open driver.

Inst nvidia-kernel-source-530-open
Inst nvidia-dkms-530-open

Maybe run
sudo apt update
again.

Okay, no idea what the issue was. I installed CUDA 12.1, it came with 530.30, and that driver installed fine. When I updated the driver vs apt install nvidia-driver-530, I know have closed 530.41, the way it should be. No idea why that did not work in the first place, but its working now.
