-====== ​Frequently Asked Questions ​======+====== ​Xfce Screensaver FAQ ====== 
 + 
 +===== Why doesn'​t the screensaver/​lock screen activate when I attempt to lock my computer? ​ ===== 
 + 
 +You are likely running an unpatched xflock4, which does not know about xfce4-screensaver.\\ 
 +This has been [[https://​git.xfce.org/​xfce/​xfce4-session/​commit/?​id=baf23e096da712084e54b47faa49c1ca99665b75|resolved upstream]], but will need to be manually added until the next Xfce Session release. 
 + 
 +All you need to do is add ''​xfce4-screensaver-command --lock''​ to the available lock commands. 
 +<​code>​ 
 +$ 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

 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. The screensaver daemon is not currently running.

 +===== 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.
 +
 +<​code>​
 +<?xml version="​1.0"​ encoding="​ISO-8859-1"?>​
 +
 +<​screensaver name="​abstractile"​ _label="​Abstractile">​
 +
 +  <command arg="​-root"/>​
 +  ...
 +</​code>​
 +
 +The compatible desktop entry, installed to ''/​usr/​share/​applications/​screensavers/​abstractile.desktop'',​ looks like this.
 +
 +<​code>​
 +[Desktop Entry]
 +Type=Application
 +Name=Abstractile
 +Exec=/​usr/​lib/​xscreensaver/​abstractile -root
 +TryExec=/​usr/​lib/​xscreensaver/​abstractile
 +Categories=Screensaver;​
 +</​code>​
  
 +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.
