Touchscreen calibration utility

Not being a xorg specialist, I know a calibration utility from binstead. But 
it only works with one specific brand of touch screens. The problem I see in 
your wish is that touchscreens tend to deliver their signals in different 
formats and in different interfaces. And that makes it hard to develop some 
generic approach. You are right in your assumption that touchscreens 
basically all do the same thing. They all produce x and y coordinates. 
Though, some yield more data like the strength of the impression and so on. 
There are also different technologies to measure the user's activities.

Sorry that I could not help. But I do understand and support your issue and 
I'd be interested to hear from you if you have found anything in that 
direction.

Best wishes,

Markus
