Upgraded from 16.04 to 18.04.1 LTS. Similar issue encountered where Fn keys are working (audio, mute, bright, volume and even wifi) except for enable/disable touchpad. However, Touchpad disabled graphic is displayed (indicating recognition) but unfortunately has no effect i.e. not able to enable/disable using Fn key (Fn+F5).
