 +It is recommended to protect the active session on your PC by using a screensaver that locks access by requiring a password. Another way, of course, is just to log out. 
  
-You can use xscreensaver to lock your screen to prevent unauthorized access while you are away from the computer. You can do this instead of logging out.+==== Gnome screensaver ====
  
-To set xscreensaver to require a password, go to Activities -> Applications -> Screensaver. This will open up a new window. At the bottom left of the window, activate "Lock Screen After" and set the time to 0 minutes for immediate locking.+Debian 8 "Jessie" uses gnome-screensaver. It can be activated by pressing "Super+L" ("Super" is the "Windows" key on either side of the space bar.)
  
-In order to activate screen lock, just press "Ctrl+Alt+L".+Look at https://wiki.gnome.org/Projects/GnomeScreensaver/FrequentlyAskedQuestions for information about the Gnome screensaver. A certain amount of configuration is possible using ''dconf-editor''.

 +xscreensaver has more configuration options than gnome-screensaver, but it needs to be set up first. 
 + 
 +To set xscreensaver to require a password, go to Activities -> Applications -> Screensaver. This will open up a new window. At the bottom left of the window, activate "Lock Screen After" and set the time to 0 minutes for immediate locking. You can also specify the kind of screen saver(s) to use. 
 + 
 +The easiest way to activate xscreensaver is to use a keyboard shortcut. First you need to define the shortcut by going to Settings -> Keyboard -> Custom Shortcuts. There you can set up a new custom shortcut like: 
 + 
 +  Name:    xscreensaver 
 +  Command: xscreensaver-command -l 
 + 
 +After you've added the action, don't forget to click on the right side of the line to specify the actual key combination, for example "Ctrl-Alt-L".
  
-There is supposed to be a "Lock Screen" item in the menu when you click on you userid at the top right of the screen, but for some reason that doesn't appear. Perhaps future research will make it possible to fix this.
