10.10 Can someone tell me how to disable the touchscreen?

[gohanssjn]

I want Pen and Touch disabled. The touch part has calibration issues and clicks when nothing is near the screen, so I just want the whole thing turned off.

How can I do this in 10.10?

It is an N-Trig touch screen on a Dell latitude XT.

Thanks!

Hello, try this:

$ synclient TouchpadOff=1

[gohanssjn]

Before I try that, is that going to disable the touchscreen or the touchpad? Because I need the touchpad.

Oh, sorry. My bad, I was not careful.

Please give here output of

$ xinput --list

Ok, next post here output of

$ xinput --list-props 14

You can try:
To turn it off

xinput set-prop 'N-Trig MultiTouch' 'Device Enabled' 0

To turn it on

xinput set-prop 'N-Trig MultiTouch' 'Device Enabled' 1

When you have the N-Trig MultiTouch device, the N-Trig Touchscreen does not report anything. The device uses the N-Trig Touchscreen for single-touch reporting when the multitouch firmware is not present.

I hope that helps.

Yay! Touch is off, but the pen still works!

Now, what would I have to do to make this persistent between reboots?

You can try:

echo "xinput set-prop 'N-Trig MultiTouch' 'Device Enabled' 0" >> .xinitrc

I have not had a chance to try it out, but the .xinitrc file should run when your session starts so it should turn off touch.

Did not work, still had touch on login screen and in session.

Thanks for all the help so far.
