Public bug reported:
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.
