compiz fusion problem
 

i installed compiz fusion by autoten but when i click it my screen displays a white splash and continues to display that.

i could not understand what is the use of this compiz fusion?

You need to remove compiz fusion from your system.

Go through a checklist of everything you will need,
and be sure that all packages are up to date.
Compiz fusion allows you to have 3d effects on your desktop.
