Where did you read this? There gets much nonsense written in the wild, partially even dangerous.
For a LTS kernel it might be a good choice to stay with it, if there are no special needs to upgrade the kernel, but 4.10 is not a LTS kernel and since some time no longer supported. So regarding 4.10 such an advice (or misunderstanding from your side?) is a really bad idea.

HOW TO CLEAN LINUX MINT SAFELY -

"First this, however: a Linux Mint version should preferably stick to the kernel series it had on release date, because with that it'll function optimally. Kernel updates should preferably only be minor newer versions within that particular kernel series. With the notable exception of very new hardware, which often needs a newer kernel series in order to work well."

PLENTY of bad ideas to choose from :)

I wrote that particular text at the time of Mint 18.1, which still had the LTS kernel series (4.4) by default. Obviously it needs an update, all the more because of the current Meltdown/Spectre crisis. Thanks for alerting me.

--Edit: done:
There's an important exception to this rule, which has to do with security. From Mint 18.2 onward, if you want to have a secure kernel, you'll need to upgrade your kernel to the 4.13 series. Or downgrade it to the 4.4 kernel series. That's because the short-lived kernel series with which Mint 18.2 and 18.3 were released, are no longer being supported.

No problem, Pjotr, I am just a newb finding my way around. I appreciate your tech savvy demonstrated on your many informed posts here on the forum. It is just hard to know which advice to follow. I appreciate your kind acceptance of the spirit of my note.

I'm not a guru of *nix based system, but it's obvious for me : Kernel updates absolutely neccessary to improve perfomance for some hardware, protect your data, etc...
But also it's a pretty risky action, I should make backup before this kind of update.
As I did just a few days ago.
So, this time exactly some nasty shit happened.
Actually I have 2 displays : first - laptop display, second - external monitor pluged via VGA.
After update laptop display stay dark and does not react for any action. (I guess I will post this question to appropriate topic)
Someone notice some issues with 4.13.0-26 ?

I think my question has been answered, thanks to all who commented. I will set this thread solved. My decision: I will follow the development of the kernel. If that one day might stop one of my computers to work, I can roll back to a previous kernel (and to the backup of my data, if necessary) - or I can think about buying a new computer (after using it some 10+ years).

Thanks again!
