Update.. so now everything works fine with the synaptics driver, no boot to 3.2.1 or 3.2.6 required. I suspect this was an xorg problem all along.
If I remove xserver-xorg-input-synaptics then the trackpad stops working (and oddly enough, the keyboard becomes really hard to use if X is running.. very hard to describe, but keypresses are lost). In my experience, the synaptics driver is really bad at palm detection, so I am not really happy about having to use it, but at this point, its my only option. Redirecting to xorg. Thanks everyone for the help thus far. ** Summary changed: - MacBookAir 4,1 trackpad does not work with synaptics driver until boot into 3.2.1 kernel + MacBookAir 4,1 trackpad does not work with evdev/multitouch driver ** Package changed: linux (Ubuntu) => xorg (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/936552 Title: MacBookAir 4,1 trackpad does not work with evdev/multitouch driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/936552/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
