Latitude 5590 - Ubuntu 18.04 - How to scroll with central button

Hi everybody,

I have a Latitude 5590 with Ubuntu 18.04 installed in dual-boot alongside Windows 10.

Inside Windows 10, I can scroll pages by holding the central button and moving the trackpoint.

Inside Ubuntu, such scrolling feature doesn't work.

Any ideas?

Thanks in advance.

I've found the answer and solved the problem.
I edited the file /usr/share/X11/xorg.conf.d/40-libinput.conf and I changed the following section (the one having pointer identifier), adding the two Option lines:

Section "InputClass"
        Identifier "libinput pointer catchall"
        MatchIsPointer "on"
        MatchDevicePath "/dev/input/event*"
        Driver "libinput"
        Option "ScrollMethod" "button"
        Option "ScrollButton" "2"
EndSection
