Is there an easy way to downgrade kernel to 4.14.x in ubuntu 18.04?
It's relatively straight-forward installing a different kernel: How to update kernel to the latest mainline version without any Distro-upgrade?
The latest kernel in the 4.14.xx
chain is 4.14.67
.
That said I've found kernel chain 4.13.0-xx-generic
which Ubuntu maintains very stable compared to the 4.15.00-xx-generic
kernel chain Ubuntu maintains. The advantage of staying on a Ubuntu kernel chain is it is automatically upgraded for you when new versions come out.
When you are on the 4.14.xx
LTS Linux Kernel Chain you must periodically review when new kernels come out and install the new ones manually using the above link.

I've been having a problem with my desktop session dying: describe in this thread: https://ubuntuforums.org/showthread....9756&p=1379652
This thread suggest the problem is with the 4.15 and 4.16 kernels: https://bbs.archlinux.org/viewtopic.php?id=235027
This problem did not exist with 16.04.x
I do use ubuntu packaged zfs.
Is there an easy way to downgrade the kernel without reinstalling 16.04 ?

Rinzwind about 5 yearsWhy would you need to downgrade? Kernels are not removed when you do an upgrade. You can pick available kernels at the grub screen.

anewbie about 5 yearsWhen I upgraded from 16.04 to 18.04 it removed the old kernel. The only kernel installed are 4.15.0 and 4.4.0.
