Still having fun setting up laptop with Ubunut. Everything works great apart from the touchpad. I've had a little play and disabled the touch click, however the pad is very sensitive to touch. I don't mind that so much, it's the fact the touch sensitive pad extends over the right and left buttons.

Does anybody know how to edit the touchpad so I can reduce the area that is registered as touch sensitive?

Or put another way I want to stop the touchpad from extending over the buttons?

I read that you could use Synaptics properties, specifically BottomEdge. But that is not found when I try to run it with the xinput command. Says I need to define it.

Thank you for any assistance.

I've continued to research the problem and found a information at: https://wiki.archlinux.org/index.php/Touchpad_Synaptics

This had the useful command:

synclient -l | grep BottomEdge
    BottomEdge              = 4478
    AreaBottomEdge          = 0

However setting the values seems to have no effect on my touchpad. Although it does correlate to the values I seen with xinput in the Edges line.

I've tried relatively large values with no effect.

synclient BottomEdge=400000

Any ideas?

I resolved this problem using the following script in the command line:

xinput set-prop "SynPS/2 Synaptics TouchPad" "Synaptics Finger" 27 30 0 
synclient AreaBottomEdge=4080

The first line seems to slow down the pointer speed and the second pushes the touchpad area up above the left and right buttons.

Worked for me on a Yoga 2 13.
