Thanks! My searches before filing the bug suggested that the log messages were symptoms, but I was unable to find any guideline on how to diagnose further.
I've uninstalled gsconnect (both the Gnome extension, and the accompanying Chrome extension), and fully rebooted. The locks still occur. Some extra information: 1. In trying to pin down the cause, I… - Uninstalled zeitgeist - Disabled tracker: https://gist.github.com/vancluever/d34b41eb77e6d077887c#non-invasive-disable-cheat-sheet Neither of these made a difference. 2. I also identified what seems to be a separate issue: https://bugs.launchpad.net/ubuntu/+source/gnome-shell-extension-desktop- icons/+bug/1826604 3. Finally, I notice differences between the bug in the default 'Ubuntu' session and the 'Ubuntu on Wayland' session. The initial bug report, above, was from 'Ubuntu on Wayland'. In the default 'Ubuntu' session: - The display and keyboard input lock, but the mouse cursor can still be moved. - The 'Key repeat discarded' and 'libinput error' log messages do not occur. Other symptoms (e.g. CPU usage spike for gnome-shell) are the same. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1826219 Title: Input locks frequently/high CPU usage after 18.10->19.04 upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1826219/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
