Now the touchpad stays disabled, both in current session & after a reboot. This seems to be poor behaviour as the user would need to manually re-enable the touchpad without the use of a mouse or get a working mouse, batteries, ect. to get the mouse back or re-enable the touchpad. Also affects a gnome-session/gnome-control-center.
