Obviously that depends on how you define "better" :-) The problem I'm facing is that with the X driver there is no way to change calibration without restarting X several times, which isn't acceptable for the application we're developing. Sure, I could fix the X driver to allow run-time changes to the calibration parameters, but that's a very large task. On the other hand, solving the problem in the kernel was dead-easy. So, I agree that solving the problem in-kernel might not be the best possible solution, it's just the only one I actually have the time to implement (and it'll work for most users). > How do other touchscreens do it? They seem to do nothing, i.e. let the problem be solved in user space.
