Spent a few hours trying to get the drivers running. I still get:
$ 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.
You’re running an old oem kernel without headers so the driver doesn’t compile. Please switch to the standard 5.15 kernel, should be available in the grub menu.
Afterwards, run
sudo apt install linux-headers-$(uname -r)
to make sure the headers are installed.
