So I ran that command (it took a while, but completed successfully) then tried nvidia-smi both before and after a reboot. Sadly its still in the same position.

From what I understood in the docs, it creates/updates a ramdisk for each kernel I have installed? By the look of it, I might have a load of kernel versions still installed, is it worth removing some of them?

Thank you for the really quick reply! I copy and pasted each of those commands exactly, and did a reboot before and after the install, but I’m still experiencing the same issues.

nvidia-smi returns the following:

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

It seems like a very strange issue.

Wow you guys work fast! I ran that line and got the following:
