Thanks @Bob (caltinay) for the libinput insight. I'm using Linux Mint 19, a Bionic based distro, and was suffering from the same issue.
libinput, in fact, was already installed. All I had to do is change the driver to libinput creating a file called /usr/share/X11/xorg.conf.d/90-libinput.conf with the following contents: ###################################### Section "InputClass" Identifier "libinput touchpad catchall" MatchIsTouchpad "on" MatchDevicePath "/dev/input/event*" Driver "libinput" Option "Tapping" "True" Option "DisableWhileTyping" "True" EndSection ###################################### Clickpad now works exactly as it should. Touch sensitivity at the bottom area (where the buttons are located) is now correctly disabled.
