[Bug 1579190] Re: Key 5 automatically pressed on some Logitech wireless keyboards
The "out of the normal cycle" kernel versions released yesterday were
for a security fix, and so do _not_ include the fix for this bug.
The "normal cycle" kernel versions that we're preparing this week _do_
include this fix. A note will be posted here as soon as those kernels
reach the -proposed archive.

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 XTEST pointer id=4 [slave pointer (2)]

⎜ ↳ AlpsPS/2 ALPS DualPoint Stick id=15 [slave pointer (2)]
⎜ ↳ AlpsPS/2 ALPS DualPoint TouchPad id=14 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
