[1] This patch works ok for Single-Touch Events however the Left Half side of the touchpad is far less accurate than the Right Half for Semi-mt events (synclient -m 10 shows f alternating constantly between 1 and 2 fingers with two fingers touching it and one finger touch erroneously reports as 2 finger touch sometimes.) I hope this is useful and maybe it could be improved and approved :) Sorry for the code quality, I am not a programmer. [1] http://people.canonical.com/~sforshee/alps-touchpad/psmouse- alps-0.10/
