Fingerprint and Trackpoint on ThinkPad X380 Yoga doesn't working

[oberst]

I installed Kubuntu 18.04 on the new Lenovo Thinkpad X380. The touchscreen, the touchpad, the keyboard, the wacom Pen, all works fine except

- the red Trackpoint in the middle of the keyboard.

~$ xinput list

It is recognized as ETPS/2 Elantech TrackPoint but it doesn't react. The programm configure-trackpoint from Think Pad Extras PPA (https://launchpad.net/~linrunner/+ar...hinkpad-extras) throws me an exception that the TrackPoint is not found. Maybe this is a newer version which is not already included in the kernel?

-the integrated fingerprint-scanner:
I think it's recognized as USB-device named Validity Sensors, Inc.

fingerprint-gui gives me No Devices found. I also tried to install fprint but this ends with the same error.

~$ fprintd-enroll 
list_devices failed: No devices available

Thank you for your time!
