Hey, I configured Xfce that whenever I suspend the screen should be locked. If I call suspend from the power-manager tray icon this works as expected but if I click the suspend button in the logout screen, the screen isn't locked. It seems to me that this button does not call xflock4 before suspending like the powermanager seems to handle the event.
