I just installed Ubuntu 12.10 on my Macbook Pro. When I click the trackpad, it is always registered as a small mouse movement as well as a click, so it drags whatever I click on. has anybody else encountered this? Is there any synaptics setting that can help? For the moment, I've enabled tap to click because normal clicking is so tough.
I didn't have this issue when running Ubuntu in a VM, but I guess that has another abstraction layer that prevents synaptics from being the one interpreting direct touchpad input.
