Hi, I am trying to install driver for Tesla K40 on Ubuntu 20.4 LTS.  
I’ve used `$ sudo ubuntu-drivers autoinstall` to install the driver. The system has installed `Nvidia-driver-470`, after installing, I rebooted the system; when checking the device with `Nvidia-smi`the result I got is “no device were found”

I attached here a nvidia bug report. Any advices are appreciate.

Thank you
