Brilliant. It worked. Thank you
Use of synclient does indeed make the touchpad tap and scroll work.
However it seems to need doing every session. That is, it does not store the configuration change in the persistence image file.
Any advice on how to get it to store changes or where to stick a script that can be run on startup every time?
