There are a number of things that can go wrong, anywhere from the kernel driver, whether mtdev is used or not (latest pymt has mtdev support), which X driver is in use, and what distro is being used. For driver tests, the mtview program (http://bitmath.org/code/mtview/) has been used successfully during development of some drivers, since it does not depend on the higher levels of the stack. Combined with evtest, it is usually possible to find the point-and-click problems. If you do find an error higher up the stack, providing a test case using the utouch-evemu project is very valuable, since it allows the hardware and the exact situation to be emulated and explicitly tested on any machine.
