Public bug reported: Steps to reproduce: - observe touchpad click-drag working normally (i.e. can click touchpad and drag an icon, or select text in any direction) - close lid to suspend (need to wait some time until red Thinkpad light above 'i' on lid starts to flash - open lid to resume - observe touchpad click-drag NOT working. Can click but not drag, or can only drag very short distance/awkwardly
Also note: - sudo moidprobe -r psmouse - sudo modprobe psmouse restores expected functionaly BUT touchpad then seems very sensitive to palm rest errors (cursor jumps to unexpected spots when typing) Similar symptoms to several related bugs (see below) but reporting separately, since: - issue still present on later hardware and software than previously reported - issue still present despite full firmware updates - slightly different experience with workaround (i.e modprobe -r psmouse / modprobe psmouse does restore functionality Related bugs: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1791427 https://bugs.launchpad.net/ubuntu/+source/libinput/+bug/1727130 https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1728778 ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: xserver-xorg-input-libinput 0.27.1-1 ProcVersionSignature: Ubuntu 4.15.0-64.73-generic 4.15.18 Uname: Linux 4.15.0-64-generic x86_64 NonfreeKernelModules: zfs zunicode zavl icp zcommon znvpair ApportVersion: 2.20.9-0ubuntu7.7 Architecture: amd64 BootLog: Error: [Errno 13] Permission denied: '/var/log/boot.log' CurrentDesktop: ubuntu:GNOME Date: Wed Sep 25 21:29:07 2019 DistUpgraded: Fresh install DistroCodename: bionic DistroVariant: ubuntu InstallationDate: Installed on 2018-11-22 (306 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 004: ID 138a:0097 Validity Sensors, Inc.
