$ cat /etc/udev/rules.d/99-touchpads-are-touchscreens.rules
ACTION!="add|change", GOTO="_end"
ENV{ID_INPUT_TOUCHPAD}=="1", ENV{ID_INPUT_TOUCHPAD}="",
ENV{ID_INPUT_TOUCHSCREEN}="1"
LABEL="_end"
This turns your touchpad into a touchscreen, should be good enough for
testing. Afterwards, reboot or run
sudo udevadm test /sys/class/input/event17
sudo udevadm test /sys/class/input/event17/device
with your event node. Note that you need both the event node and the parent
input device to avoid both flags being set.
Cheers,
Peter
