I'm having issues with the 'AlpsPS/2 ALPS GlidePoint' (HP zBook Studio G4). It is working but is treated as a mouse device, effectively resulting in all the settings I make in 'Mouse and Touchpad' > 'Touchpad' being ignored. E.g. I can disable 'Tap to click' but with no effect. I can even disable 'Enable touchpad' and it will still work.
These are the relevant lines from the Xorg log file:

I've manually disabled tapping as follows (but still no effect):
enter code herexinput set-prop 'AlpsPS/2 ALPS GlidePoint' 'libinput Tapping Enabled' 0
-->
$ xinput --watch-props 'AlpsPS/2 ALPS GlidePoint'

Any hints on how to get this thing working as an actual touchpad would be much appreciated! :)
EDIT: This is not a specific Mint issue - I tested with latest Fedora and it is the same problem there (I hoped that a newer libinput/gtk/whatever version would probably solve the issue).
EDIT 2: Doesn't work on KDE/Kubuntu w/ latest Plasma either.
I had this same issue. Fixed it by doing:
sudo modprobe -r psmouse; sudo modprobe psmouse
