If you check your ~/.xsession-errors there should be a warning about setting a LockCommand. The simplest fix is to actually set it via `xfconf`: $ xfconf-query --channel xfce4-session --property /general/LockCommand --set "lock_command_of_your_choice" If it's not set, the following commands will be tried in the order specified: xflock4 xdg-screensaver lock xscreensaver-command -lock If none succeed, the function xfce_screensaver_lock() returns FALSE, which makes it look like it's useless. Note that it's not supposed to work 100% outside Xfce4.
