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?

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.

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.
