Keyboard and mouse stop working randomly

[Phill]

Lenovo Yogo 300 has a keyboard, touch pad and touch screen. Keyboard and mouse stop working, I am unable to see any pattern to the problem. This affects both Wayland and Xorg sessions, log-in and lock screen and desktop environment. Originally mistaken for a full system freeze, but touch-screen works fine. Putting computer into standby and resuming resolves the issue, but sometimes happens within seconds of resuming, sometimes it works for ages without a problem.

Filed against gdm3 due to these events found in the log, but this may be unrelated:

Problem started immediately after installing 17.10.1, 17.04 had been used flawlessly since it's release on this hardware. Note that "gnome-session" is installed which I normally use, but as the problem occurs on the lock and login screens I guess it's nothing to do with that.

I've seen this kind of bug occur on other laptops, and in those cases it was a hardware fault (the ribbon cables for the keyboard and touchpad randomly lose contact).

For the moment let's assume your case is still a software problem. So can you please try:
  1. Booting 16.04 and use it for a while. Does the problem occur there? https://www.ubuntu.com/download/desktop
  2. Booting 18.04 and use it for a while. Does the problem occur there? http://cdimages.ubuntu.com/daily-live/current/
  3. Does installing older or newer kernel versions fix the issue? kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D

17.04 did not have any problems, I never had 16.04 on this computer.

An update to the kernel yesterday seems to have resolved this issue (linux-image-4.13.0-31). So it's not worth investigating further at this point in time.

However, the kernel update seems to have introduced a full system freeze that occurs less often than the original problem, but this is another matter. I think I'll just run 17.04 until 18.04 comes out.

I'm not sure if this should be marked invalid or fixed, so I'll leave that to someone else.

"Incomplete" is fine. If there are no more comments for 60 days then it will automatically change to Expired.
