I have had the same problem in Xubuntu as documented in

But now I am facing the same issue in Lubuntu as well. I can't find "Enable display compositing" in Lubuntu though.

Look at the image for the error message:

Lubuntu, does not use Composition, you can a very basic compositing manager in the form of xcompmgr just make it auto start when you log in.

sudo apt-get install xcompmgr will Install it.

yes thanks . :) – Raja Aug 17 '12 at 12:12

XCompMgr works, but a great alternative is compton.

To install, open a terminal (Ctrl+Alt+T) and execute the following commands:

sudo add-apt-repository ppa:richardgv/compton  
sudo apt-get update && sudo apt-get install compton

and then

sudo leafpad /etc/xdg/lxsession/Lubuntu/autostart

and add the line

@compton -c -r 16 -l -24 -t -12 -G -b

Then reboot and you should be good to go.
