Generic Ubuntu 22.04 - RTX 3070 graphics card - RmInitAdapter failed! (0x26:0x56:1477)

I have installed a virgin ubuntu 22.04 on a lenovo yoga laptop connected to a Razer Core Chroma X via Thunderbolt that has an Nvidia RTX 3070 installed in it.

I have run:

$ sudo apt purge nvidia-*
$ sudo apt autoremove

Here are my screenshots. Ideas anyone? Thank you in advance.

I am only allowed to post 1 pic? Huh?

Here is another screenshot:

That did it. The grub directive. Many many thanks!
