Title:
touchpad multipoint touching opens Unity Dash
Status in “xserver-xorg-input-synaptics” package in Ubuntu:
Confirmed
Bug description:
On a Dell 15z with a Cypress touchpad real work is almost impossible
because the inevitable palm touch on the pad opens the Unity Dash.
synclient reveals that the palm touch is registered as a 3-point
touch, which is consistent with the observation that a clean 3 finger
touch does in fact open the dash.
Given that it is virtually impossible to avoid brushing the top
corners of the touchpad, having the Dash shoved in your face over and
over again is a real problem.
Using the syndaemon without the "-t" option to disable mouse movement
during typing also kills the multi-touch behaviour, but this is not a
real fix because the latency in mouse movements it introduces is about
as bad as the problem is partially solves. Only partially because if
you pause to think during typing you are likely punished with a Dash
in your face as you go to resume typing.
