Package: gnome-shell Version: 3.16.3-2 Severity: normal While on the lock screen, pressing Ctrl-PrintScreen will flash the screen as though taking a screenshot of the lock window, and Ctrl-Shift-PrintScreen will switch to the plus-shaped cursor and allow selecting a region to screenshot. As far as I can tell, the screenshot doesn't actually get saved anywhere; however, the keybindings shouldn't work at all. (It looks like PrintScreen doesn't work, but the rest do.)
