Public bug reported:

The evdev driver needs a calibrator for touchscreens, since -evtouch is
obsolete and the calibrator that was shipped with it doesn't work with
evdev.

>From [1]:

"A generic touchscreen calibration program for X.Org.

xinput_calibrator is created to fill the gap of touchscreen calibration
software, featuring:

    works for any standard Xorg touchscreen driver (uses XInput protocol)
    mis-click detection (prevents bogus calibration)
    dynamically recalibrates the evdev driver
    outputs the calibration as xorg.conf.d snippet or HAL policy file
    and more"

We need it, because there is no calibrator left after evtouch is
removed.

The author has packaged it for several distributions, including Debian
and Ubuntu, and the package has gone through Debian Mentor review [2]
(most of which have been fixed since). The packaging is currently at the
same place as the upstream code [3], but will move got git.debian.org
under pkg-xorg team maintenance.
