Basically you add this to xorg.conf: Section "Extensions" Option "Composite" "Enable" EndSection And in the kcontrol Window Behavior, there should be a Translucency option, turn it on. You might have to restart X. That should do it. You'll want to adjust some windows so they don't go opaque on you most likely, you can do that by right-clicking on their titlebar and it's in Advanced I think. Windows Properties, etc Your card DOES have to be 3d and be reasonably fast for this, plus it uses a bit of memory, so I wouldn't do it on a wimpy system.
