I can't seem to download Nvidia driver on my Linux Ubuntu


I am currently using an ASUS laptop that has a NVIDIA rtx 4060 laptop as my GPU and I have a Ubuntu 20.04.6 LTS. I’m trying to install and run Nvidia driver on my laptop to run ROS. I tried to run nvidia driver 550 through additional drivers on software & updates but when I did it a black screen with blinking underscore showed up. I got back to the original login screen through purging the nvidia file through 'sudo apt-get purge ‘nvidia*’.

But I think I did something wrong with the commands which resulted with no additional drivers showing up in my additional drivers interface anymore. When I check my settings it shows:

Processor = MD® Ryzen 9 7940hs w/ radeon 780m graphics × 16
Graphics = llvmpipe (LLVM 14.0.6, 256 bits)
Gnome Version = 3.36.8

When I run nvidia-smi it shows:
NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

For your amd gpu, you will need a recent kernel and firmware
kernel: https://github.com/zabbly/linux#installation
firmware: http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_20220329.git681281e4-0ubuntu3.29_all.deb

Afterwards, please run nvidia-bug-report.sh as root and attach the resulting nvidia-bug-report.log.gz file to your post.

Your CPU from 2023.
Yout kernel - Ubuntu 20.04.6 LTS - 4 years old, your processor did not exist when this kernel released.
And in case of “laptop” - it not clean if your monitor connected to integrated amd or nvidia.
If monitor connected to amd-integrated - then you need working amdgpu drivers that only in latest kernel for your 2023 cpu.

It worked thank you!
