The Ubuntu phone does not use the GEIS API nor does it support X. It uses the Android/Linux evdev interface exclusively for input. As for the Synaptics driver, it is usually configured by default to not act as a proper (XI2-style) multi-touch device and will do gesture recognition internally and report as additional button events. You may want to reconfigure X to use the evdev driver for the device instead. -- Stephen M.
