This bug still exists but really curious on Kubuntu 16.04 and after upgrade on 16.10.
This bug exists first at login screen, thats mean, if you have an encrypted ubuntu system with passphrase required at boot time. At boot time the external logitech keyboard with german layout and unifying receiver works fine with german layout like the internal laptop keyboard. But at login screen the external keyboard changed to us layout, the internal keyboard not!
And now it would be extremly strange. After a time between 5 and 90 minutes working with the wrong layout on the external logitech keyboard, the external keyboard changes to the german layout themself! And until reboot the external keyboard keep the german layout.
