Comment 34 for bug 1820899

Thanks for all that. Your Xorg log (and Google) says it is a touchscreen device:

I am not sure if libinput *should* be handling touchscreens at all. In the least, the log recommends some kind of manual configuration:

[ 20401.793] (II) config/udev: Adding input device Neonode AirBar 13.3 (/dev/input/mouse1)
[ 20401.793] (II) No input driver specified, ignoring this device.
[ 20401.793] (II) This device may have been added with another device file.

Regardless, I think the libinput developers would have the best idea. Can you please log a bug here:

  https://gitlab.freedesktop.org/groups/libinput/-/issues

and then tell us the new bug ID?
