If you want the compviz effects you have in kde to work in kde as well, then google with the terms: cool solutions suse compiz xgl kde
If it is the kde window transparency effects you want then add
Code:
Section "Extensions"
Option "Composite" "on"
EndSection
to xorg.conf and enable effects in kde. You can access the configuration by right clicking on a kde window border or through KMenu -> Personal Settings -> Desktop -> Window Behavior -> Translucency.
However, I've found that this slows down performance to an unacceptable level.
