Nvidia GPU always idle at 0%

General system Newbie
1

Recently upgraded to a nvidia RTX 4060 Ti, but monitoring with nvtop shows it is sitting at 0% usage at all times no matter what I’m doing. For example, running unigine-heaven benchmark gives frame rates around 10 FPS (about 1-2% what is expected) while nvtop reports 0% GPU usage. Similar results for games; they run, but VERY low framerates. I suspect it might be a driver issue that I’m having trouble tracking down, like the GPU is using some sort of fallback. Can anyone provide some insight into what might be happening?

Other notes:

  • A nvidia GTX 1650 works as expected when I swap it back in with no other system changes. I.e. power down, swap the cards over, power on, everything is running fine.
  • I have confirmed the new RTX 4060 works as expected on a Windows machine.
  • nvtop shows GPU memory is being used.
  • I get this error when running nvidia-settings, not sure how to interpret it since the nvidia-settings GUI launches anyway and looks fine as far as I can tell.

I’m not sure why nvidia-settings would be failing, but what is the output of ls /dev/dri? I have a dual GPU setup and had to fidget with it a lot to get it working; check out this part of the sway Github description for a bit of background. Specifically, setting WLR_DRM_DEVICES= to the correct /dev/dri device in your /etc/environment may help you.

I should note that I do not have a dual GPU setup and no integrated graphics either. This is kind of confusing since I am still getting an output from the GPU, it just doesn’t seem to being used under load. I.e. no temperature increase, fans remain idle, seemingly 0% usage and a tiny fraction of the performance expected for 3D rendering.

ls /dev/dri

by-path  card0  renderD128

I added WLR_DRM_DEVICES=card0 to /etc/environment, but no change.
