As you have Intel graphics there's no need to switch back to nouveau (only users using the proprietary nvidia graphics drivers NEED to do this PRIOR to installing a different kernel series) .. but yeah installing ukuu would probably be the easiest way to upgrade the kernel.



Manual installation

Assuming you want the 4.19 kernel from the Ubuntu kernel PPA) download these files and put them in a folder called say kernel-419 in your home folder
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.19/linux-headers-4.19.0-041900_4.19.0-041900.201810221809_all.deb
and
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.19/linux-headers-4.19.0-041900-generic_4.19.0-041900.201810221809_amd64.deb
and
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.19/linux-image-unsigned-4.19.0-041900-generic_4.19.0-041900.201810221809_amd64.deb
and
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.19/linux-modules-4.19.0-041900-generic_4.19.0-041900.201810221809_amd64.deb
then run:
Code: [Select]
cd ~/kernel-419
then
Code: [Select]
sudo apt-get install ./*.deb
then reboot.

Note:- Expect to see messages about missing firmware for amdgpu .. that is not a problem ;)



To UNDO

To REMOVE that kernel
Code: [Select]
sudo apt-get remove --purge linux-headers-4.19.0-041900 linux-headers-4.19.0-041900-generic linux-image-unsigned-4.19.0-041900-generic linux-modules-4.19.0-041900-generic
then reboot.



BTW, there's no guarantee this will work on its own .. the problem could just as easily be with the rest of the graphics stack (intel xorg drivers and/or mesa version).

And considering this kernel will NOT automatically receive security updates, you may be better served just waiting for the 18.04 HWE to be released .. but your call, can't hurt to experiment I guess, it's all undoable.

Cheers guys.  I installed UKUU.  It's pretty nifty tool.  I'd never hear of it before, thanks Zeb, I like it ;).  I tried installing the latest v4.18 kernel using UKUU.  This is the kernel Xubuntu 18.10 is using.  It installed like a charm.  I then deleted the my test Xubuntu 18.10 partition.  This messed up GRUB.  It throws up all kind of errors at boot.  I can't specific about them because they display for a picosecond then they're gone.  I've tried using chroot from a Live Session to reinstall it.  Even that is throwing up errors.  I think I'm going to reformat the drive and start again.  I'll call this one SOLVED.  Again, thanks for all the help and advice guys  ;) .

So did the 4.18 kernel stop the flickering in Peppermint 9 ?

Oh yes, it worked a treat.  There's no hint of a flicker  ;).  I wish I'd left the Xubuntu partition intact though.  Peppermint 9 is working great on this machine.  It's just GRUB with all the errors and warnings.  I figured if I can't fix it by reinstalling it using chroot, a fresh, full install is the safest route to achieve a stable installation  ;).
