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 ?

    Why would you need to downgrade? Kernels are not removed when you do an upgrade. You can pick available kernels at the grub screen. – Rinzwind Aug 31 '18 at 09:17
  • When 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. – anewbie Sep 01 '18 at 13:00

It's relatively straight-forward installing a different kernel: How to update kernel to the latest mainline version without any Distro-upgrade?

4.14.67.png

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.

  • But will it work ok with the ubuntu version of ZFS (which is a kernel module) or will i have to manually install ZFS if i go this route ? – anewbie Aug 31 '18 at 19:58
  • Also you said 4.13 is installable from ubuntu but under 18.04 i only see 4.15.x and 4.4. How would I move to 4.13 ? – anewbie Aug 31 '18 at 20:00

I ended up fixing the issue via buying a cheap amd gpu. Kind of cheap but easier than dealing with the rest of the crap.
