The capabilities of the touchpad on the new ASUS UX31 Zenbook leave much to be desired. The touchpad works like a mouse, but no vertical or horizontal scrolling. I contacted a developer who works for Sentelic. He said:
Unless driver does some non-trivial works based on coordinates output, I'm afraid that it won't have scrolling support at this moment.
Windows driver does scrolling in driver where current Linux driver doesn't have such feature, yet. Additionaly, given that the resource is quite limited at this moment, I'm afraid that there is no firm schedule for scrolling support in Linux driver.
How can we get this driver to do some "non-trivial works based on coordinate output"?
