@stefanoStefano Marinelli #touchpad on #FreeBSD can be an issue because FreeBSD's meta-port dependencies still force installation of the xf86 "synaptics" driver. But you can still force using the generic #libinput for touchpads (which then typically works fine) like this:
# cat /usr/local/etc/X11/xorg.conf.d/40-libinput.conf
Section "InputClass"
Identifier "libinput touchpad catchall"
MatchIsTouchpad "on"
MatchDevicePath "/dev/input/event*"
Driver "libinput"
Option "ClickMethod" "clickfinger"
