[Bug 1932528] Re: Touchpad stopped working after using as a tablet

Fri Jun 18 12:48:16 UTC 2021

Thank you for taking the time to report this bug and helping to make
Ubuntu better.

I see no evidence of a system upgrade (from 20.10 to say 21.04) having
taken place... the installation media was 21.04 & system is still
currently 21.04, thus package was changed from `ubuntu-release-upgrader`
to the `linux` kernel.

Bug reporting is about finding & fixing problems thus preventing future
users from hitting the same bug.

I suspect a Support site would be more appropriate, eg.
https://answers.launchpad.net/ubuntu. You can also find help with your
problem in the support forum of your local Ubuntu community
http://loco.ubuntu.com/ or asking at https://askubuntu.com or
https://ubuntuforums.org, or for more support options please look at

** Package changed: ubuntu-release-upgrader (Ubuntu) => linux (Ubuntu)

Title:
  Touchpad stopped working after using as a tablet

Status in linux package in Ubuntu:
  New

Bug description:
  Hi Everyone.

  So my touchpad has stopped working now out of the blue. I have a
  Lenovo Yoga 3 Pro 1370, and I installed Ubuntu yesterday.

  It was working perfectly, but it has stopped working as soon as I got
  into tablet mode.

  This laptop has the ability to fold its keyboard, so I did that and
  turn the laptop in 90 degrees (which the screen also turned due to the
  gyroscope). When we do this, its normal that the cursor disapears so
  we can you use only the touchscreen as a tablet, however when I turned
  back to a laptop the touchpad hasn't worked ag=0ain.

  I have rebooted the system, but still not signs of it.

  I have executed "cat /proc/bus/input/devices", but didn't find
  anything related to the touchpad, as the result shows below, so I
  think it's a kernel issue, right? Any thought how I could fix this?

  Thank you!

  *************udpate*************************

  After a full shutdown, the touchpad is working again. However.
  everytime I go into "tablet mode" by folding the keyboard, the
  touchpad continues to work (and is not disabled as expected).

  After 5 minutes working, if has stopped working again and required a
  full restart (shutdown and turn-on afterwards).
