Bug Description
== SRU Justification ===
[Impact]
Raydium touchscreen on ThinkPad L390 doesn't work.
[Fix]
Use I2C_HID_
resetting the device.
[Test]
User confirmed the touchpad works with the patch.
[Regression Potential]
Low. This fix limits to one device and is quite trivial.
== Original Bug Report ===
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:/
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/
- `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.
