Comment 35 for bug 1900254

I have the same issue as lyntier.

xinput
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ USB Keyboard Mouse id=14 [slave pointer (2)]
⎜ ↳ MSFT0001:00 06CB:CE2D Mouse id=16 [slave pointer (2)]
⎜ ↳ MSFT0001:00 06CB:CE2D Touchpad id=17 [slave pointer (2)]

I tried adopting the script as following:

#!/bin/bash
modprobe i2c_hid
echo "i2c-MSFT0001:00" > /sys/bus/i2c/drivers/elants_i2c/unbind
echo "i2c-MSFT0001:00" > /sys/bus/i2c/drivers/i2c_hid/bind

but the service was not able to run due to the script failing:

systemctl status touchscreen.service

but dmesg shows that the device is already using i2c_hid:

Could anybody please help me? I've installed Linux for the first time and just got this notebook.
