Title:
Lenovo ThinkBook 14-IML Touchpad not detected
Status in linux package in Ubuntu:
Confirmed
Bug description:
Hi, i have a new Lenovo ThinkBook 14-IML. It shiped with Win10
preinstalled. I booted once into Windows to check all devices.
Everyting worked including the touchpad.
Then I've installed Ubuntu 18.04. Unfortunately, the touchpad is not working.
xinput list does not show a touchpad device.
Other users seem to have the same problem, like this new question on
