Thanks for the bug report. Firstly please try disabling any extensions you might have installed. Please also run:
cd ~/.local/share/gnome-shell rm -rf extensions and log in again. If the bug still happens then please check for crashes of the gnome- shell process by following these instructions: https://wiki.ubuntu.com/Bugs/Responses#Missing_a_crash_report_or_having_a_.crash_attachment I expect a crash of gnome-shell is the most likely explanation and will result in it restarting. ** Changed in: gnome-shell (Ubuntu) Status: New => Incomplete -- 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/1972812 Title: The operating system does not ask for a password after unlocking the screen.
