Similar problem here. When I get back from the lock screen a new additional dock appears. I have two monitors, and the dock pinned to one, the additional dock appears in the other monitor and uses a different style and settings.
The problem appears when using dash-to-dock and disabling ubuntu dock, via tweak tools. Using the gnome shell lg tool, the ubuntu dock extension indicates an error: "dockManager is null". Maybe ubuntu-dock doesn't understand that dash-to-dock is already running? Restarting gnome shell removes the new dock, restoring behaviour. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1716982 Title: Dash to Dock still visible on lock screen under gnome-shell To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell-extension-ubuntu-dock/+bug/1716982/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
