(SOLVED) Kernel 4.8.0-x and Zorin 12.1

I have noticed in Ubuntu Cleaner that both kernel 4.4.0-x and 4.8.0-x are now both installed.

I found a comment at http://www.omgubuntu.co.uk/2017/02/down ... 6-04-2-lts

“If, however, you want to reap the hardware support improvements of the Linux Kernel 4.8 and associated goodies you’ll need to opt-in to receive them.

How? By running one single, simple command:

sudo apt install --install-recommends xserver-xorg-hwe-16.04”

Do we need to do anything in Zorin 12.1 Ultimate to take advantage of Linux Kernel 4.8?

There was some other poster who broke his Zorin install blaming Zorin. Please remember that Zorin strive for stability. When it is safe to do so I expect it will filter down in due course through system updates. As an allegorical example, would you replace Windows 7 Kernel with that of Windows 10 and expect it to work?

No - it was just that kernel 4.8.0-x has arrived via Software Updater.

Perhaps Software Updater is not controlled by Zorin - I thought that it would be.

Which software update channel is the one controlled by Zorin, I wonder?

Not bothered - only curious to understand.

If you launch Software and Updates and then go to authentication tab you will see a Zorin PPA so that as well as key updates from the Ubuntu server it will also pull Zorin updates. I don't know how all of it works but I suspect there will be some form of script to prevent higher kernels from crashing Zorin.
