I suspect you have one of the "v4" touchpads, and if so the ALPS driver does not yet support any multi-finger functionality for your device. You can check by identifying the input device for your touchpad (you can use lsinput to do this) and then running 'cat /sys/class/<input_dev>/properties'. If the value is 0 then there's no semi-mt support for your touchpad.
