Trackpad scrolling/two finger click not working in Ubuntu 15.04 on Macbook Pro 12,1

[austin]

As the summary says, I'm unable to scroll or two finger ("right click") on ubuntu 15.04 running on a recently purchased macbook pro (12,1).

I've compiled all hardware information (devices/xinput/Xorg.0.log) into "bug.text" as the file attachment for this report doesn't seem to allow multiple file attachments.
