Hi,

I previously installed liquorix on Ubuntu 19.04 and it just appeared in the grub menu next boot.
(under Advanced optoins in the grub menu...)

I recently upgraded the PC to 19.10.

Then re-installed liquorix.

But this time it's not in the grub menu.

In both cases using apt.

What did I do wrong or not do?

How do I fix it? If possible...

What happens when you run sudo update-grub? For example on an Ubuntu 19.10 VM of mine:

:: Code ::
$ sudo update-grub
Sourcing file `/etc/default/grub'
Sourcing file `/etc/default/grub.d/init-select.cfg'
Generating grub configuration file ...
Found linux image: /boot/vmlinuz-5.4.0-15.1-liquorix-amd64

Have you tried purging the kernel packages and reinstalling? Seems like something broke during your upgrade.

You should be able to run apt-get purge .*liquorix to remove all pre-existing Liquorix packages, then follow the instructions on liquorix.net to add packages for your system.

Ok, so that done, it now shows up as before in the grub boot menu.

But, if I select liquorix, when the boot is complete and login to desktop, the desktop is a different layout (compared to booting the Ubuntu provided kernel), one of 3 monitors is blank, and the mouse moves lag behind a lot (like seconds).

But, works fine with the kernel installed by Ubuntu Studio 19.10 .

As noted, liquorix was installed originally on UB Studio 19.04, worked fine with wither UBS19.04 kernel or liquorix.
After upgrade to UBS 19.10 liquorix was disabled in the repositories. Initially I just enabled it.

I have now apt purged and removed from the repositories, then followed the instructions on the liquorix web site.

because of the mouse lag I can't use liquorix kernel at this point.

Maybe a DKMS driver issue?

Can you install inxi and give the result of "inxi -Fxxz" in the terminal?

I do know that no Nvidia driver in Debian at all yet supports a build on a 5.5 kernel--I got 440.59 from Nvidia this AM and packaged it for Buster (MX 19) and Stretch with backports (MX 17) in order to get it working on my Optimus laptop, so perhaps the builds failed on your Ubuntu install, too.
