Drivers for Lenovo Thinkpad E550 Touchpad

Question

I have just received my new laptop, a:

Lenovo Notebook ThinkPad E550

And have installed Ubuntu version:

14.04.1 LTS

To my disappointment, it does not seem to be possible at all to scroll using the touchpad. Neither using the two finger gesture, nor by holding down the centre button.

A quick google search turned up

This web page

Which, though it does not list this particular model, implies that it may be a driver problem. Unsurprisingly, Lenovo does not seem to supply a driver for Ubuntu, so I was wondering if anybody here had any suggestions?

Edit in accordance with pilot6's comment:

xinput; dmesg | grep pnp

Please [edit] your question and add output of xinput; dmesg | grep pnp terminal command. — Pilot6, Jul 31 '15 at 16:51
First upgrade kernel as described in one of the answers. sudo apt-get install linux-generic-lts-vivid and reboot. If that does not help, then we can continue. — Pilot6, Jul 31 '15 at 17:29
Yep, that seems to've done it, thanks @Pilot6, I've also up-voted the answer — Au101, Jul 31 '15 at 17:50
I used this solution http://askubuntu.com/questions/398568/psmouse-serio1-alps-unknown-alps-touchpad-in-a-lenovo-ideapad-flex-15?answertab=votes#tab-top, and got some improvement: the scrolling now works, but the the touchpad keys are not anymore. — elvisplatini, Apr 07 '15 at 21:31

I was able to fix this (I have the same laptop) on my Ubuntu 14.04 installation using a newer kernel (v3.19+ from Vivid or later). I ran:

sudo apt-get install linux-generic-lts-wily

did a reboot and the touchpad seems to be working now (source).

Other people seem to be able to solve this problem by using a newer kernel too: https://github.com/duncan-bayne/mint-setup/issues/41

Also, if you have VirtualBox, your computer will keep reporting or bugs, a possible workaround is to uninstall to VirtualBox and install the latest one.

Do you have exactly same laptop model? Or you just fixed "some similar problem" this way? – Pilot6 Jul 31 '15 at 17:01
I do have the exact same laptop. – Arpit Bhakta Aug 19 '15 at 17:33

Just to add here, that I looked up the specific linux kernel for my distribution. I've had the same problem on the Thinkpad E555 with Ubuntu 16-LTS, and used

sudo apt-get install linux-generic-lts-xenial

Which is specific for the new Ubuntu 16.04 LTS (xenial) distribution. It's working great.
