Then, instead of pressed once, the key seems to be not released and pressed continuously until another key is pressed. I have described the behavior in more detail under https://askubuntu.com/questions/1051508/hanging-keys-under- ubuntu-18-04. It does not occur when I boot in Windows or Ubuntu 16.04, so it is not related to the hardware. It does not occur when I plug in an external keyboard, so it is not related to general Ubuntu keyboard settings. It does not occur when the power cable (USB-C) is unplugged, only when t is plugged in. /var/log/syslog logs the following when the cable is plugged in: "kernel: [ 9821.899727] thinkpad_acpi: EC reports that Thermal Table has changed" ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: linux-image-4.15.0-32-generic 4.15.0-32.35 ProcVersionSignature: Ubuntu 4.15.0-32.35-generic 4.15.18 Uname: Linux 4.15.0-32-generic x86_64 ApportVersion: 2.20.9-0ubuntu7.2 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: ludwig 1919 F.... pulseaudio CurrentDesktop: ubuntu:GNOME Date: Sun Aug 19 00:21:56 2018 InstallationDate: Installed on 2018-05-02 (108 days ago) InstallationMedia: Ubuntu 18.04 LTS "Bionic Beaver" - Release amd64 (20180426) Lsusb: Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 003: ID 5986:2113 Acer, Inc Bus 001 Device 002: ID 046d:c046 Logitech, Inc.
