Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

On ubuntu 11.10, with Unity desktop:

tapping top-right corner of the touchpad triggers 'Paste'
tapping top-left corner => 'Copy'
tapping bottom-right corner => 'Right-click'

(I've discovered this through experiments).

Obviously, that's intentional. There must be settings for that. I've looked through Settings->Mouse & Compiz Settings Manager but failed.

How do I disable these triggers?

In terminal, type: synclient RTCornerButton=0. This solved the problem on me.

Execute synclient -l to list all configurations.

I was looking to solve this problem as well. I don't use a mouse; I use touchpad exclusively. My preferred code editor is vim and I was fed up with unintentional copy and pasting while touching the corners of my touchpad. It seems solution is easy:

  1. Go to Applications -> System Tools -> System Settings
  2. Click on Mouse and Touchpad option.
  3. Click to open the Touchpad tab.
  4. Uncheck "Enable mouse clicks with touchpad" option.

That's all! Enjoy.

This would disable even left click with touchpad, not a good solution. –  theharshest Sep 28 '13 at 9:43
Yes, this actually deservers a down click. But since I've got a few of those haunting me for what I considered to be good answers, I won't do it to you. –  Dennis Apr 2 at 5:47
