My problem was solved due to help from the Dutch forum.
A simple translation:
First of all install the drivers for your videocard, so you have
3d support
Next; paste the next line into Konsole:
sudo nvidia-xconfig --composite --no-dynamic-twinview --damage-events --allow-glx-with-composite --add-argb-glx-visuals
(xconfig is being modified to the right settings with this command)
Add the next line to the repository address:
http://paketler.pardus.org.tr/contrib-2007/pisi-index.xml.bz2Now we update all packages.
Now install Compiz Fusion, this can also be done
with a simple command in the Konsole:
sudo pisi install -c desktop.opencompositing
After installing reboot the computer and you should all be set.
With many thanks to Pjotr of the Dutch forum
