desktop settings / effekts

Hejsa i

Jeg er helt grøn mht Linux, men har lige installeret *Kubuntu 9.04 på en Packhard Bell laptop. Den har et Nvidiia Go kort indbygget..

Det som undrer mig at hvis jeg prøver at enable effekterne får jeg denne medd. :
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.

Jeg ville gerne ha' den cube til at funge, ??

Nogen der kan hjælpe :-)
