[kde-freebsd] Superkaramba transparancy

[Steven Friedrich]

My superkaramba themes are not transparent, like in KDE3.

When I try to enable desktop effects, I get an error dialog:
Failed to activate desktop effects using the given configuration options. 
Settings will be reverted to their previous values.

Check your X configuration. You may also consider changing advanced options, 
especially changing the compositing type.

Where are these options?
