I recently tried to allow my laptop to have different wallpapers on each individual work space. I did everything in this video.

I didn't have the compiz settings manger before hand. I had to download it.
Even following the directions perfectly I don't have different wallpapers.
But that's not my main problem. I liked having my launcher hiding until I moved my cursor to the left. Since I attempted this wallpaper fiasco, when it hides, it stays hidden. The only way I can access it is if I go into system settings>appearance>behavior and clicked "Auto hide the launcher." onto the 'off' position. Now it's there all the time. It's really bothering me. All my windows are smaller because full screen won't overlap the launcher. Any ideas?
