Public bug reported:
EGalax touch screen "Pen" is identified (apparently by udev) as a
tablet. libinput then ignores the "Pen" and the touchscreen does not
work.
*** Part of output from journalctl ***

Inc. USB TouchController Pen: is tagged by udev as: Tablet

Inc. USB TouchController Pen: libinput bug: missing tablet capabilities:
resolution.Ignoring this device.
*** Creating the following udev rules file, fixes the touchscreen for me ***
/etc/udev/rules.d/91-libinput-egalax-local.rules
ACTION=="add|change", KERNEL=="event[0-9]*", ENV{ID_VENDOR_ID}=="0eef", \
ENV{ID_MODEL_ID}=="0001", ENV{ID_INPUT_TABLET}="", ENV{ID_INPUT_TOUCHSCREEN}="1"
*** Note ***
I don't yet know enough about the interaction between libinput, udev and other
packages to be sure what the proper long term fix is.
