I got a Lenovo V330 and installed Ubuntu 16.04. Everything works, except for the touchpad.
When I was looking at solution installing the latest mainline kernel solved this problem
acpi-id of my touchpad is i2c-ELAN061E:00
I checked ACPI ID is in at the end of elan_i2c_core.c of the latest mainline kernel. But not able to find it
https://elixir.bootlin.com/linux/v4.19/source/drivers/input/mouse/elan_i2c_core.c
if there are no prebuild kernel with your acpiid, you must add your id to elan_i2c_core.c file, patch and build your kernel packages manual.
Not sure I how to add this patch any help??
