Bug description:
  I have a K520 Logitech keyboard and sometimes something starts to keep pressing key 5.
  It mostly happens when I leave the computer alone for some time, but sometimes also just during regular usage.

  It seems that this is a Linux specific issue as no one is complaining
  about this issue under Windows, but a couple of people are complaining
  for different versions of Ubuntu.

  It is always 5 and WladyXX3740 claims on the Logitech forum that:
  "happens on Ubuntu 15.10 and 16.04, does not happen on Ubuntu 15.04, probably kernel related."

  Here is where most of the people are complaining:
  https://forums.logitech.com/t5/Keyboards-and-Keyboard-Mice/Ubuntu-15-10-and-K520-key-5-automatically-pressed-resulting-in/td-p/1488639

  I discovered that this is related to my Logitech keyboard by running this command:
  xinput test-xi2 --root

  Here is the device list:
  ⎡ Virtual core pointer                    	id=2	[master pointer  (3)]
