Comment 0 for bug 1849721

I have bought new Lenovo ThinkPad L390 with touchscreen and it works fine on Windows, but not on Ubuntu.
I've tried Ubuntu LTS 18.4, 19.4 and 19.10. I've tried installing Ubuntu and running Live USB image, and also other distributions (Manjaro i3, Kubuntu).
There is an Ubuntu certification with the same touchscreen using Ubuntu 18.4: https://certification.ubuntu.com/hardware/201812-26720

Other info:
- `xinput` is showing touchscreen: "Raydium Touchscreen id=10 [slave pointer (2)]"
- if I list device props using `xinput list-props 10`, I see device: `Device Node (277): "/dev/input/event9"`
- `cat /dev/input/event9` does not produce anything
- `xinput --test-xi2 --root` does not produce any touchscreen events, even though events from other devices are successfully shown

Also, attached `ubuntu-bug` report.
