Description mike 2013-01-04 15:27:01 UTC 
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.

There does not appear to be a configuration option to ignore these 3 point events.

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 it 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.

Please record the event sequence that triggers it with evemu and attach both device description and sequence here.

This is a mass change of bugs. Bugs assigned to me that haven't been updated in the last 3 years are closed as WONTFIX, because, well, let's at least be honest about it.

Please do not re-open unless you have a really good reason to do so (e.g. you're fixing it yourself). If it hasn't been fixed in the last 3 years, it probably won't be fixed anytime soon either. Sorry.
