I have to add [method=file] to _all_ slides that have _either_ overlays or listings. It doesn't work just to put a \pdsetup after the \maketitle.
Why not?
But ... lf and rf have to appear in the preamble and thus a footer appears on the title slide. Is there anyway to get rid of it like I use \thispagestyle{empty} in regular LaTeX documents??
Put the \pdsetup{lf=...,rf=...} after \maketitle -Hendri.
