Indeed, it works when I insert
Section "Extensions"
    Option "Composite" "Disable"
EndSection
Yes, I have
    DefaultDepth  24
I notice that XFdrake removes "Disable"
when I enable 3D effecte.
So it looks as if have to choose between
having 3D effects and being able to run the
python scripts. Is that correct?
