Unfortunately, we not yet support ABS mode events in DDE Linux as we
concentrated on multi-touch mode touchpads. I wonder why your
touchscreen is not driven in the latter mode, but this may be because
the stylus is used.

Do you know of any EFI/BIOS mode settings for the touchscreen/stylus
that may help? If not, we had to enable ABS mode in the USB HID driver
for graphics tables/stylus devices. Would you mind to send all
report/log entries prefixed with [init -> drivers -> usb_hid_drv]?

This shows the stylus reports BTN_TOOL_PEN and BTN_0, which may
cause the confusion in nitpicker . For robustness, you may insert the
following options into /config/event_filter into the <remap> node
where <key> nodes are defined.

  <ignore-key name="BTN_0"/>
  <ignore-key name="BTN_TOOL_PEN"/>
