Or install newest mainline test kernel, but it had less testing, YMMV:

I installed newest mainline kernel, it did work for me.

sudo add-apt-repository ppa:cappelikan/ppa -y

sudo apt update

sudo apt install mainline -y

mainline check

mainline install 7.3.1

sudo apt -f install

reboot

Who is cappelikan? Why should I trust them?

That "mainline" is only installer tool:

https://github.com/cappelikan/mainline

You don't need to use that mainline installer.

You can download mainline kernel .deb files directly from Ubuntu:

https://kernel.ubuntu.com/mainline/

https://kernel.ubuntu.com/mainline/v7.3.1/

I found here Canonical commenting about status of new kernels:

It this ad from some battery company?

1) Issues showed unicorn. Reloading page.

2) Issues showed Not found.

Anyway, GitHub Actions for building new release has progress. Good enough.
