Touchpad Scrolling Sensitivity

Briefly describe your issue below:
I’m running latest Parrot Os 4.8, with MATE Desktpo in Virtualbox 6.0. My host machine is a Dell XPS 15 with Ubuntu 19.10 and Gnome.

I’m having a very low sensitivity in Parros OS when i try to scroll with two fingers on my touchpad while the sentivity is very good on my host machine with Ubuntu.

In Parrot OS I don’t have a “touchpad” tab to adjust the setting in the Mouse settings.

I’ve tried to change the way VirtualBox emulate my touchpad but nothing change either i set "USB Tablet, USB Multi-touch Tablet or PS/2 Mouse under Settings>System>Motherboard>Pointing Device in Virtual Box

In Parrot OS i’ve tried to play with xinput to change libinput settings but it never affects the touchpad scroll sensitivity, just the pointer speed and acceleration.

if i run libinput measure touchpad-pressure
i get “Unable to find a touchpad device”

so it feels like parrot OS doesn’t see my touchpad.

Any idea how i could adjust the sensitiviy ?

here are more infos:

Altight so after spending the day trying to make it work i gave up and installed Parrot OS in a Vmware virtual machine instead of Vbox and it works perfecty.

cheers
