[Bug 1580732] Re: wireless keyboard - repeating characters unattended


The same problem with Logitech K800, no such problems in 14.04.

This happens even if the keyboard is turned off. I had my computer
locked and keyboard turned off during the night, in the morning the
password field in the login screen was full of dots (infinite 5s) and
lightdm had crashed. I had to alt+F6 and restart lightdm.

Apparently this bug also 'eats' some of my intentional number 5 key
presses, i.e. the first key press of 5 sometimes does not do anything.

  wireless keyboard - repeating characters unattended

Status in linux package in Ubuntu:

Bug description:
  When doing nothing at all, the screen (eg an editor, mail message,
  terminal etc) will start displaying '5' rapidly across the screen.

  I am a recent ubuntu 16.04 user - a fresh install "Linux TimPassingham
  4.4.0-22-generic #39-Ubuntu SMP Thu May 5 16:53:32 UTC 2016 x86_64
  x86_64 x86_64 GNU/Linux"

  I was previously on 14.04 and had no such issues.

  My keyboard is a Logitech wireless MK700/710.  There is nothing wrong
  with it in normal running, nor when using windows (dual-booted).

  I am not alone, and it is the same key (5) for others seeing this
  issue.  See https://askubuntu.com/questions/761522/ubuntu-16-04
