Steps to reproduce: On a fresh installation of Lubuntu 14.04, run: $ xdg-screensaver lock Expected: [screen locks] Actual: ERROR: Unknown command 'lock' However, it is possible to lock the screen via: $ light-locker-command -l The xdg-screensaver script uses one of several external utilities, depending on the desktop environment. It falls through to screensaver_xserver() at line 697 (or 740, because the function is duplicated!), which does not include a lock function, even though one is available. This is a problem because xfce4-power-manager (part of lubuntu- desktop) uses xdg-screensaver to lock the screen on suspend under Lubuntu, but this has no effect. This may represent a security risk as a computer configured to (and reasonably assumed to) lock on suspend will actually resume straight to the desktop.
