I followed simple guides consisting in adding the lines
synclient TapButton2=2
synclient TapButton3=3
into a .sh script made executable by
chmod +x /home/name/touchpad.sh
and make it automatically run on startup with
gsettings set org.gnome.settings-daemon.peripherals.input-devices hotplug-command “/home/name/touchpad.sh”
Now when I recover from hibernation the two finger tap acts like the right mouse clic and the three finger tap don't do anything (at least I think), just as I changed nothing. The behavior should be two finger tap acting like the central mouse clic and the three finger tap as the right one. I can make the change effective by simply opening (nothing more!) a new terminal.
