Thanks for the bug report. Dash-to-panel is not supported by Ubuntu. Also I believe the only way you can still have extensions loaded on the lock screen is if one or more of them are buggy and crash when they are told to deactivate.
Please start by deleting all local extensions: cd ~/.local/share/gnome-shell/ rm -rf extensions and then log in again and tell us if the bug still occurs. ** Package changed: gnome-shell (Ubuntu) => ubuntu ** Changed in: ubuntu Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/2073016 Title: lock screen leaves left dock exposed and clickable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/2073016/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
