title: Changing wallpaper using pcmanfm by crontab
body: <p>I made a simple bash script that changes the wallpaper for a random picture from my wallpapers directory using pcmanfm. It's something like that:</p>
  
  <pre><code>#!/bin/bash
  
  pcmanfm -w "$(find /home/likewise-open/MAPS/lucas.cardeal/Pictures/Wallpapers -type f | shuf -n1)"
  </code></pre>
  
  <p>I want that automatically, so u put the script on crontab. But it has no effect when its called by crontab. What's wrong with my script? How can I fix it?</p>
  
  <p>Thanks</p>
