How to fix touchpad scrolling in the Lenovo IdeaPad Z510 under Ubuntu 14.04 LTS

When I’ve updated Ubuntu to 14.04 in Lenovo IdeaPad Z510 laptop then touchpad section disabled from “Mouse and Touchpad” settings (screen below)

To fix it you need install a lot of software. I try it but it not works for me.

The most fast and simple solution is upgrade linux kernel to 3.14.1.

The workflow is next:

32-Bit Systems

Download the .deb packages.

$ wget kernel.ubuntu.com/~kernel-ppa/mainline/v3.14.1-trusty/linux-headers-3.14.1-031401_3.14.1-031401.201404141220_all.deb

$ wget kernel.ubuntu.com/~kernel-ppa/mainline/v3.14.1-trusty/linux-headers-3.14.1-031401-generic_3.14.1-031401.201404141220_i386.deb

$ wget kernel.ubuntu.com/~kernel-ppa/mainline/v3.14.1-trusty/linux-image-3.14.1-031401-generic_3.14.1-031401.201404141220_i386.deb

Install packages.

sudo dpkg -i linux-headers-3.14.1-*.deb linux-image-3.14.1-*.deb

Reboot your system.

sudo reboot

64-Bit Systems

Download the .deb packages.

$ wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.14.1-trusty/linux-headers-3.14.1-031401_3.14.1-031401.201404141220_all.deb

$ wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.14.1-trusty/linux-headers-3.14.1-031401-generic_3.14.1-031401.201404141220_amd64.deb

$ wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.14.1-trusty/linux-image-3.14.1-031401-generic_3.14.1-031401.201404141220_amd64.deb

Install packages.

sudo dpkg -i linux-headers-3.14.1-*.deb linux-image-3.14.1-*.deb

Reboot your system.

sudo reboot

After reboot your “Mouse & Touchpad” settings will be the next:
