Trying to install nvidia drivers on my ubuntu server. Running nvidia-smi after install and reboot yields the following

$ nvidia-smi NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

My ubuntu version is$ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 22.04.4 LTS Release: 22.04 Codename: jammy

The server is a penguin computing gpu server, with several different tesla cards installed. (Penguin Computing / Gigabyte MG50-G20 2U 8x GPU E5-2600v3/v4 Graphics Server)

Examining the /proc/driver/ folder shows no nvidia sub folder.

Driver was installed via the following command

sudo apt-get install nvidia-driver-440-server

I have also tried using the different drivers and have rebooted after each time (545, 440, and the non server versions)

Have purged nvidia installs and run autoremove.Have tried installing nvidia toolkit directly using this guide to encounter the same errorhttps://developer.nvidia.com/cuda-downloads?target_os=Linux&target_arch=x86_64&Distribution=Ubuntu&target_version=22.04&target_type=deb_local
