Touch screen not enabled out of the box

Fujitsu Lifebook 1610 has touch screen.
Installed Xenial. From the first boot Xorg logs show touch screen is detected. But somehow it is not enabled.
(I haven't tested any other operating system on this computer)

This need to be run after each boot:
sudo /usr/bin/inputattach --daemon --always --fujitsu /dev/ttyS4

Workaround:
/etc/rc.local
+/usr/bin/inputattach --daemon --always --fujitsu /dev/ttyS4
