Comment 12 for bug 1397021

Since the patch is ignored upstream, I made a ppa with a patched ideapad-laptop module.

It can be installed by

sudo add-apt-repository ppa:hanipouspilot/ideapad-laptop
sudo apt-get update
sudo apt-get install ideapad-laptop-dkms

Note for 14.04 users:

The package is made for Ubuntu 14.04.2 with 3.16 kernel. It fepends on linux-generic-lts-utopic

Of anyone wants to use 3.19 kernel, install packet for vivid.
And remind me to update ppa, when 14.04.3 is released.

But I hope that someone from Canonical pushes the patch upstream.
