All you need to do is add ''xfce4-screensaver-command --lock'' to the available lock commands. $ cat /usr/bin/xflock4 PATH=/bin:/usr/bin:/usr/local/bin export PATH # Lock by xscreensaver or gnome-screensaver, if a respective daemon is running for lock_cmd in \ "xfce4-screensaver-command --lock" \ "xscreensaver-command -lock" \ "light-locker-command --lock" \ "gnome-screensaver-command --lock" do $lock_cmd >/dev/null 2>&1 && exit done ---- ===== Why doesn't my monitor turn off automatically? ===== **Display Power Management Signaling** (DPMS) has been disabled by another application. This can be confirmed and resolved using the ''xset'' command. To check if DPMS is disabled, run the below command. $ xset -q DPMS (Energy Star): Standby: 1200 Suspend: 0 Off: 3600 DPMS is Disabled If DPMS is disabled, it can be turned back on with ''xset +dpms'' $ xset +dpms $ xset -q DPMS (Energy Star): Standby: 1200 Suspend: 0 Off: 3600 DPMS is Enabled Monitor is On ---- ===== Why doesn't my screensaver activate automatically? ===== ''**Possibility A**'' The screensaver daemon is not currently running. You can check this by looking at the running processes, or just run ''xfce4-screensaver'' to start it up. Only one instance will run at a time, and you will be notified if it is already running. $ xfce4-screensaver ** (xfce4-screensaver:9788): WARNING **: 01:15:42.354: screensaver already running in this session ''**Possibility B**'' Another application has disabled the X11 screensaver. This can be determined by running ''xdg-screensaver status''. $ xdg-screensaver status disabled If this command outputs "disabled", try running the following commands to enable the screensaver. $ xset s blank # Sets the X11 screensaver mode to "blank" $ xset s 300 # Sets the X11 screensaver timeout to 5 minutes $ xdg-screensaver status enabled ---- ===== Where are all the screensavers? ===== Xfce Screensaver uses Xscreensaver-compatible screensavers. These can usually be installed separately from the main Xscreensaver package. If you've already installed the screensavers and they still are not available, you may need to create desktop entries for them so they can be found by Xfce Screensaver. In the future, this process will be automated by Xfce Screensaver. Meanwhile, it is not hard to make your own. **''Example''** By looking at ''/usr/share/xscreensaver/config/abstractile.xml'', all of the importing information can be found. ... The compatible desktop entry, installed to ''/usr/share/applications/screensavers/abstractile.desktop'', looks like this. [Desktop Entry] Type=Application Name=Abstractile Exec=/usr/lib/xscreensaver/abstractile -root TryExec=/usr/lib/xscreensaver/abstractile Categories=Screensaver; In this example, you can see that the ''Name'' key is derived from the screensaver label, ''Exec'' and ''TryExec'' both use the screensaver binary path, and the ''Exec'' key also includes the command arguments.
