Can't change nvidia power limit after update

Since last update, this command:

~$ sudo nvidia-smi --power-limit 60

now gives me output:

Changing power management limit is not supported for GPU: 00000000:01:00.0.
Treating as warning and moving on.
All done.

However, this used to work without a problem, and I kept my power limit lower than default, because I'm using a laptop - and with 80W, GPU would start heating up enough to then throttle itself and start stuttering.
Same thing happens on both standard and LTS kernel.

Any idea how can I get this feature back - or do I need to attempt to degrade everything back to before update?

Re: Can't change nvidia power limit after update

Assuming this is a regression/change in the nvidia driver you'd need to try downgrading nvidia-dkms and nvidia-utils to the matching previous version and installing the linux-headers package so the module can be built.

If you don't have nvidia-dkms already (in your cache) see https://wiki.archlinux.org/title/Arch_Linux_Archive

Thank you, I'll definitely try this!
I've never done the downgrade before, so this is great information. I'll mark as Solved if it helps, and I know for sure its regression on their side.

downgrade can't solve the power limit problem?

nvidia is making things worse and worse. 530 driver is a huge crap. bad performance, no more power limiting. thousands of reasons to not buy it again. i wish i could swap the gpu in my laptop
