[Bug 1579190] Re: Key 5 automatically pressed on some Logitech wireless keyboards
I also get this behaviour with my Logitech K520 keyboard and unifying
receiver, on Ubuntu 16.04 and on 15.10 before that.
I'm currently running
4.4.0-22-generic #40-Ubuntu SMP Thu May 12 22:03:46 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
The same bug has been reported on the RedHat bug tracker:
https://bugzilla.redhat.com/show_bug.cgi?id=1278818
According to that, the hid-logitech-hidpp driver might be the culprit.
I'm interested to hear that Viktor has not yet seen the problem with the
4.6 kernel. Viktor, please keep us posted when you've run it for a bit
longer!

Title:
Key 5 automatically pressed on some Logitech wireless keyboards
Status in linux package in Ubuntu:
Incomplete
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:

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