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:
