[kde-linux] making windows transparent ???

[manju p]

Hi all,
I have gone through  transset-df tool to make windows transparent,
I  want to vary opacity from 0 to 100. I have tried with transset-df
with the tutorial given . I have enabled the xcomposite
extension in  xorg.conf file in the following way.


Section "Extensions"
        Option "Composite" "Enable"
EndSection

but still i am not able to make window transparent in kde (linux). Is
there i need to do something else??if  anybody knows pls let  me know,

Thanks in advance
