Touchpad not working on Lenovo V330

[vishalgarg-bluebash]

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??

I had same problem on lenovo ideapad 330

Solution:
1. install ubuntu 18.04
2. download kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.18.16/
linux-headers-4.18.16-041816-generic_4.18.16-041816.201810200431_amd64.deb
linux-headers-4.18.16-041816-lowlatency_4.18.16-041816.201810200431_amd64.deb
linux-headers-4.18.16-041816_4.18.16-041816.201810200431_all.deb
linux-image-unsigned-4.18.16-041816-generic_4.18.16-041816.201810200431_amd64.deb
linux-image-unsigned-4.18.16-041816-lowlatency_4.18.16-041816.201810200431_amd64.deb
linux-modules-4.18.16-041816-generic_4.18.16-041816.201810200431_amd64.deb
linux-modules-4.18.16-041816-lowlatency_4.18.16-041816.201810200431_amd64.deb
3. dpkg -i *.deb

You can install this kernel on ubuntu 16.04, but there are problems with depends.
