Different wallpapers on each workspace in ubuntu

Wallpapers are same on each workspace in ubuntu default,here is a way to make wallpapers different on each workspace,but you must have installed CompizConfig Settings Manager,and you will lose any shortcut on desktop,so install Avast window Navigator for better results.


Note:Due to bug, different wallpaper doesn’t work in Ubuntu 10.10 Maverick. But now it works in Ubuntu 11.04 Natty. For some can’t find Wallpaper in CompizConfig Setting Manager, type this in terminal to install plugin-extra:

sudo apt-get install compizconfig-settings-manager compiz-fusion-plugins-extra 

Goto System–>Preferences–>CompizConfig Settings Manager(Advanced Desktop Settings)

 

choose Wallpaper on(if not go to Desktop Cube,click to go to Appearance–>background images),and click on it to go to its configuration page,click New and add the wallpapers you want

 

 

press Alt+F2 and then type " gconf-editor " and Enter.
Goto apps–>nautilus–>preferences and deselect show_desktop 
and then close it.

Now you are Done....!!!!! Enjoy with new Wallpapers...!!!!!
