As suggested in the upstream issue, you need to set the /general/ShowScreenshots to false like so: $ xfconf-query --channel xfce4-session --property /general/ShowScreenshots --set false The part of code responsible for emitting the beep has been around for a long time. It's done so as to notify of a taken screenshot, which is used to represent the current session in the list of saved sessions. You could argue that it should be disabled by default but I guess it's better to provide some feedback and let the user know.
