HP X2 10-p005na mini laptop Touchpad & Touch screen problem

Thanks for your help.
I looked at the link but it’s all a bit beyond me.
Getting nowhere with the clickpad scroll which is disappointing as it difficult to use without it.

I am getting somewhere with the touchscreen.
Mate 16.04 - No right click, no scroll, no zoom
Mate 17.04 - No right click, no zoom but scroll works
Ubuntu 16.04 - scroll & zoom work,
after command (on Ubuntu 16.04)
gsettings set org.gnome.desktop.a11y.mouse secondary-click-enabled “true”
right click works but is very temperamental, only works about 1 in 4 tries, I think this is down to it detecting tiny movements when holding for 3 seconds. Doesn’t work at all on either Mate 16.04 or 17.04.
Just need to get it to work on Mate 16.04

Thanks
JD
