It sounds like the affected system is uniquely broken. The simple answer would be to do a backup and then wipe/reinstall it from scratch.
The complex answer would be to check for gnome-shell extensions, uninstall any non-Ubuntu ones. And to remove the relevant gtk-2 libraries and see what else the system warns you is depending on those, which is likely inclusive of the cause of this bug. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1838919 Title: Slow and lost keyboard and mouse events To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1838919/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
