“Unable to determine the device handle for GPU 0000:21:00.0: Not Found”

Graphics / Linux Linux
#1

OS: Ubuntu 20.04.5 LTS
GPU: 2 x RTX3090

When I’m typing command ‘nvidia-smi’ it shows “Unable to determine the device handle for GPU 0000:21:00.0: Not Found”.

This is the output of ‘nvidia-debugdump --list’:
Found 2 NVIDIA devices
Error: nvmlDeviceGetHandleByIndex(): Not Found
FAILED to get details on GPU (0x0): Not Found

The nvidia-bug-report shows like this:

Do you know how to fix this issue?
Thank you!

Please switch to the proprietary kernel modules instead of -open in Sotware&Updates or set the necessary module option.
