Comment 90 for bug 1810183

If the touchpad firmware can't do it by itself, or we can't find a way to enable it, it is not too difficult to write a kernel driver that will use touchpad events and convert them into keyboard events.

Another option is to create a user space driver, like xderver-xorg-input-libinput, xserver-xorg-input-evdev, etc that will catch touchpad events and work similarly to the python script.
