'No devices were found' after installing cuda 11.02 on Ubuntu 20.04 for RTX3080

Thanks for continued help! I posted new thread and was not succesful. They also suggested it is a secure boot problem.

There was no options like this. I had erase disk and clicked ‘advanced’ and could select using LVM or ZFS. I selected LVM?

Same results. After rebooting after driver install, I get stuck on Asus loading screen.

I am really hoping there is a solution since I paid a lot for this laptop to run nvidia driver stuff and I cannot return it since i swapped the os.
