Setting "AreaBottomEdge" on xorg.conf causes touchpad to stop working

[Pedro Nariyoshi]

I am having trouble to use continuous drag on my MBP 8,1. I checked this bug report here: https://bugs.launchpad.net/utouch/+bug/681942

And tried the workaround suggested by comment #3, but it only causes my touchpad to stop working. I am not sure if that's what's causing it, but I had no xorg.conf before this, so the content of the file is the workaround alone.

I'm using Precise x64

Hi Pedro,

Please attach the output of "xinput list-props <device id>" for your trackpad.

There was a very recent change to the axis ranges reported by macbook trackpads through X. It may be that you need to update your bottom edge area values.

As a side note, you might find the new clickpad support to be a better solution. I hope to merge it into synaptics soon.

I'm not very familiar with Clickpad support. Are you suggesting I force the use of a different driver or that I compile a patched synaptics driver?

[Chase Douglas (chasedouglas)]

Pedro,

I just uploaded a new version of xserver-xorg-input-synaptics with clickpad support. Please try it out without setting the Synaptics Area property. It should make press-and-drag work without having to mask out a bottom area of the trackpad.

[Pedro Nariyoshi (pedro-nariyoshi)]

AWESOME! Thank you very much! It works perfectly!

[Pedro Nariyoshi (pedro-nariyoshi)]

Hmmm, a new problem however, "two-finger click -> right click" no longer works. ):
I'll look for a bug report with these characteristics, otherwise, should I file a new bug?

[Chase Douglas (chasedouglas)]

Two finger click interferes with clickpad press-and-drag. We had to disable it for the time being. I hope that we can bring it back once some finer heuristics have been developed.

We will probably enable right click by adding a right button area in the lower right corner of trackpads. When you press in that area it will cause the right button to be pressed instead of the left button.

I haven't seen any bug reports about the two-touch functionality being disabled. Please open a new report so we can track any solutions for it, including enabling the right button area.

Thanks!
