Bug Description
Binary package hint: xserver-
occasionally tapping the touchpad will open the right click menu, or paste into a terminal
seems to be related to 2 finger emulation on touchpads that fake it
http://
On trackpads that only report pressure data, the number of fingers touching the trackpad may be inferred from the amount of pressure reported. However, the pressure likely varies by device and perhaps with environmental factors (temperature, humidity, etc.). Between Maverick and Natty, upstream made this pressure usage the default, but this is causing issues when the threshold is too low.

I think a more long term approach would be to up the default threshold so it doesn't fire accidentally. However, that would require more testing than we have time for right now.
I'm giving a +1 on adding this patch. I'd like to see the git commit sha1 in the patch header with an explanation of where the patch came from so we can evaluate the patch easier later on.
Thanks!
