I've never seen this behaviour before so wonder if it's caused by any of the modifications you've made to this system.
Please start by uninstalling all of these extensions: 'openweather-extens...@jenslody.de', 'dash-to-d...@micxgx.gmail.com', 'clipboard-indica...@tudmotu.com', 'places-m...@gnome-shell-extensions.gcampax.github.com', 'refresh-w...@kgshank.net', 'NotificationCounter@coolllsk', 'permanent-notificati...@bonzini.gnu.org', 'removeaccesibility@lomegor', 'variety_control@manjaro' and then reboot. We need to look at extensions first because so many bugs are caused by extensions. And we require that you uninstall extensions and not just disable them because buggy extensions can still interfere with the system. ** Changed in: gnome-shell (Ubuntu) Status: New => Incomplete -- 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/1864325 Title: On press of space key, lock screen got into a loop of trying to show the password field Status in gnome-shell package in Ubuntu: Incomplete Bug description: I woke the laptop from sleep and pressed "space" key to unlock. Computer went crazy and started a loop of trying to display the password field. Also, there were multiple dropdowns on top of each other for the system tray menu. I use variety, but i am not sure if this is the cause or it is some gnome-shell bug or both. Links to video: https://photos.app.goo.gl/3PxSPsDC5pSkK4P16 Also attaching a journalctl prevboot.
