Thanks. The best guess I can make is a problem in upower or the Nvidia driver (comment #15). Those are definitely performance problems (100% CPU for no obvious reason) and could well explain why the keyboard stops responding.
Maybe next we need to look at the system log in detail... If you can recover from the problem without rebooting then please run: journalctl -b0 > curlog.txt If you have to reboot to recover from the problem then please run this after rebooting: journalctl -b-1 > prevlog.txt and send us the resulting log file. ** Also affects: nvidia-graphics-drivers-390 (Ubuntu) Importance: Undecided Status: New ** Changed in: nvidia-graphics-drivers-390 (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to nvidia-graphics-drivers-390 in Ubuntu. https://bugs.launchpad.net/bugs/1812014 Title: keyboard not responding after suspend after some time Status in gnome-shell package in Ubuntu: Incomplete Status in nvidia-graphics-drivers-390 package in Ubuntu: Incomplete Status in upower package in Ubuntu: Incomplete Bug description: I work on Lenovo laptop y-700. When I resume system after suspend, keyboards stop working, and sometimes there are performance problems visible when playing videos. It happens not immediately but after a few minutes or even a few hours of working. Restart or shutdown does not finish correctly and I need to hold the power button for a few seconds. --- ProblemType: Bug ApportVersion: 2.20.10-0ubuntu13.1 Architecture: amd64 CurrentDesktop: ubuntu:GNOME DisplayManager: gdm3 DistroRelease: Ubuntu 18.10 GsettingsChanges: b'org.gnome.shell' b'had-bluetooth-devices-setup' b'true' b'org.gnome.shell' b'app-picker-view' b'uint32 1' b'org.gnome.shell' b'favorite-apps' redacted by apport b'org.gnome.desktop.interface' b'gtk-im-module' b"'gtk-im-context-simple'" InstallationDate: Installed on 2018-08-06 (165 days ago) InstallationMedia: Ubuntu 18.04 LTS "Bionic Beaver" - Release amd64 (20180426) NonfreeKernelModules: nvidia_modeset nvidia Package: gnome-shell 3.30.1-2ubuntu1.18.10.2 PackageArchitecture: amd64 ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=pl_PL.UTF-8 SHELL=/bin/bash ProcVersionSignature: Ubuntu 4.18.0-13.14-generic 4.18.17 Tags: cosmic Uname: Linux 4.18.0-13-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip kvm libvirt lpadmin plugdev sambashare sudo _MarkForUpload: True To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1812014/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
