Just a thought, with Ubuntu going to the NON LTS 6.8 kernel, does this mean that Ubuntu and conversely Mint will be using more of the latest kernels to keep up with new CPU/GPU technology?
I don't think so. Ubuntu will maintain it themselves.
Look at "Distribution kernels" here:
https://www.kernel.org/category/releases.html
Many Linux distributions provide their own "longterm maintenance" kernels that may or may not be based on those maintained by kernel developers. These kernel releases are not hosted at kernel.org and kernel developers can provide no support for them.
And also are LTS kernels effectively dead since they only last two years?
On the Linux side yes, "LTS kernel" does not have much meaning anymore to me. 2 years is not "long term".
On the Ubuntu side, no. I think Ubuntu will simply provide their normal 5-year support by themselves. Just more work for them.
I wonder if that is behind the Ubuntu decision?
I absolutely think so.
They wanted to start off with an "as new as possible" kernel to buy as much time from upstream as they could.
That just makes sense. They are trying to minimize the LTS maintenance they have to do by themselves.
Work on 6.8 barely finished in March, so that's the newest possible starting point Ubuntu could have chosen for an April release.
It's a tough squeeze and it's risky but I can understand their decision.
This way, at least they are covered until 26.04 release, without having to switch.
so if Ubuntu starts pushing out 6.8/6.9/6.10 etc kernels will Mint follow?
I don't think Ubuntu will do that (except for the usual HWE stuff), but if they did (for LTS), yes Mint would follow them of course.
Well, maybe I'm wrong: Clem said
Ubuntu 22.04.x releases used HWE kernels, and version 24.04 is set to use kernel 6.8.
During the last two years we didn’t observe significant differences in terms of stability between LTS and HWE series. Both were pretty stable. A growing number of users with new laptops/chipsets relied on EDGE images to be able to install Linux Mint though.
Linux Mint 22 will follow Ubuntu going forward and ship with new kernel series release after release.
Not really sure what this means, it's too vague.
"Release after release" could mean that 22.1 will get a newer kernel,
22.2 will get a kernel newer than that, etc.
So maybe you are right actually! I guess we'll see.
I still think Ubuntu will definitely have a 5-year long unchanging kernel version,
at least for their business customers.
I would be very surprised if they didn't.
A big kernel change / upgrade can cause significant problems for business users.
