Comment 202 for bug 2034477

For all Linux beginners that don't want to compile their own kernel:

It seems that it's already possible to download and install a pre-compiled kernel via GUI:

Simply follow these instructions: https://9to5linux.com/you-can-now-install-linux-kernel-6-5-on-ubuntu-heres-how

You'll need to enter the following commands into your terminal:

sudo add-apt-repository ppa:cappelikan/ppa
sudo apt update && sudo apt full-upgrade
sudo apt install -y mainline

After that is done you will find an application called "Mainline Kernels" in your desktop-environment.
Start that application and install a new Kernel (I installed kernel 6.5.11).

After you installed that kernel, enter this line in your terminal:

sudo apt --fix-broken install

Restart your notebook and enjoy your built-in keyboard and trackpad.

PLEASE NOTE: Like yourself I'm a linux-noob. I can only confirm that this works on my configuration:
Ubuntu 22.04/Gnome 42/Kernel 6.5.11

But in my case it works like a charm.

Good luck!
