I am experiencing this issue too since the upgrade to 18.10. Sometimes in addition to the launcher I can even see an open program! Cannot use the program interface though before going to the unlock screen by pressing super + l and unlocking the system.
I have gnome-tweaks installed, used it only to activate the Yaru theme which was not working after the upgrade (bug 1798984). So I guess that doesn't qualify as play with it. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1769383 Title: Ubuntu dock/launcher is shown on the lock screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1769383/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
