Upgrades and newer kernel

Upgrades and newer kernel

I installed Xubuntu on my new laptop and a lot of things didn’t work properly (hard lockup when screensaver started, screen brightness, sound volume, media keys etc). Then I read that my hardware (AMD Ryzen 7 4700U) needed a later kernel. So I followed the instructions here https://www.tecmint.com/upgrade-kernel-in-ubuntu/ and installed kernel 5.8.9. Everything (except the fingerprint reader) works beautifully. It’s gorgeous.

Now I have messages saying updates are available, but it wants to install linux-image-5.4.0-48-generic. I think this would probably break things on the laptop again. I see that there is now a release 5.8.10 on https://kernel.ubuntu.com/~kernel-ppa/mainline/. Should I just download and install that? Is this the way things have to go now until the stock Ubuntu releases a version with a later kernel in it that has the appropriate drivers in it (20.10 maybe)? This is the first time I have gone “off piste” with a non-standard kernel and I’m not really sure how things should be done.
