For me, sometimes after login login overlay is not disappeared and prevent from showing any window, but mouse and maybe keyboard events still delivered to some screen areas (see screenshoot).
I do not have any hardware keys, such as yubikey Fortunately, Alt+F2, "r" helps me. ** Attachment added: "LoginOverlayBug.png" https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1824874/+attachment/5379697/+files/LoginOverlayBug.png -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1824874 Title: undismissable, unclickable authentication dialog left on screen (top- left corner) after policykit authentication [pushModal: invocation of begin_modal failed] Status in gnome-shell package in Ubuntu: Confirmed Bug description: In disco, when policykit prompted me for a password in order for update-manager to dispatch instructions to aptdaemon to perform package updates, the password dialog remained on the screen after I clicked 'authenticate'. The window is not clickable, it appears not to even be a window - mouse presses are received by the window underneath. The exception is that the 'cancel' button is active and receives mouse events - but clicking it does nothing. This may be a gnome-shell issue rather than policykit.
