I don't think he minds. As far as I know, that project is unmaintained for some years. The only touchscreen calibration software of which I know it is actively maintained is xinput_calibrator, and now evcalibrate : ) > - Evcalibrate uses a very simple approach to determining the filpx, flipy, > swapxy values.

I'm speaking from my experience with xinput_calibrator: We seem to have quite a different approach: in dependencies, the way the clicks are read, maybe even the way we calculate the calibration, ... I think it would be good to see what we can learn from eachother, to avoid duplicate work etc. Kind regards, Tias _______________________________________________ xorg mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/xorg
