Nvidia is recognized by sysmaint but not by user

Development

Steps to install Nvidia:

Then nvidia will be recognized when running sudo nvidia-smi on sysmaint side.

But on user side nvidia is not usable by user because nvidia is within admin level not user.

Side story:

I have successfully made vfio to work in KS:

Nvidia → vfio (user level) → Tools like KVM (VMs) can use Nvidia.

(Needded: Detachment of Nvidia (dGPU) from being used by the system (root). Only rely on the CPU Internal GPU (iGPU).)

So likely for whats going on is that the username user cant deal with nvidia because of permission issue.
