Status in fprintd package in Ubuntu: Won't Fix Status in gnome-shell package in Ubuntu: Won't Fix Status in fprintd package in Fedora: Won't Fix Bug description: When waking my laptop screen up at the lock screen, it takes a very long time to display the password prompt (definitely longer than 30s, possibly longer than 1m - I didn't time it). I notice that while waiting for the password prompt, the screen is showing a full list of (obfuscated) desktop notifications. After logging in, I used the gnome-shell interface to clear the notifications; then I locked my screen again, at which point hitting the space bar caused the password prompt to show up immediately. So it looks like the time to display the password prompt might scale linearly with the number of notifications; which is not useful, because there is a finite number of (obfuscated!) notifications that will be displayed on the lock screen, and AFAIK you can't interact with them through the lock screen at all. So we shouldn't be wasting time processing (and presumably rendering) notifications that will never be visible.
