This is not entirely true.

For the Colibri iMX.7 xinput-calibrator was launched twice initially.
Once by the XDG launch and once by the XSession script
/etc/X11/Xsession.d/30xinput_calibrate.sh.

The formfactor file https://github.com/Freescale/meta-fsl-arm/blob/mast
er/recipes-bsp/formfactor/formfactor/mx7/machconfig sets
HAVE_TOUCHSCREEN=1.
As a workaround we now override machconfig for our machine.

So for me the question remains if installing xinput-calibrator by
itself should launch the calibrator or if this should be conditional on
a config provided by the formfactor package.
