The screensaver setting of Enlightenment (Enable X screensaver) does not appear to work; it does not start the daemon at startup.
Maybe the (Enable X screensaver) is not meant to be a interface to Xscreensaver. If you just need a simple blank-screen/lock-screen. Read http://forums.bodhilinux.com/index.php?/topic/3175-enable-x-screensaver-working/
A possible solution for this, though probably not the best, follows. What we will do is add the Xscreensaver daemon to the startup programs of Enlightenment.
If Xscreensaver is not already installed run this command:
sudo apt-get install xscreensaver
Copy the following text into any text editor (Leafpad, for example):
[Desktop Entry] Exec=xscreensaver -nosplash Icon=xscreensaver.svg Terminal=false StartupNotify=true Name=Screensaver e17 Comment=Start screensaver daemon Type=Application Categories=Settings;DesktopSettings;Security; X-Ubuntu-Gettext-Domain=xscreensaver
Save this file as
Now you can add this as a startup application. Navigate to Main Menu → Settings → All → Apps → Startup Applications. Under the Tab for Applications you will now see an entry for Screensaver e17; click on that then click Add. Close the window, then Main Menu → Enlightenment → Restart (any open applications will continue running through the e17 restart).
Xscreensavers will now be running, and will automatically start each time your system starts up.
