Public bug reported: 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."
