There is a question about how not to number some slides: Beamer: \nonumber equivalent for slides?
However the slides themselves still have their number printed.
How can I suppress output of that as well?
MWE:
\documentclass{beamer}
\usetheme{Dresden}
\setbeamertemplate{footline}[frame number]{}
\begin{document}
%do not want slide number here
\begin{frame}[noframenumbering]
\titlepage
\end{frame}
\begin{frame}
Some actual content here
\end{frame}
%and here
\begin{frame}[noframenumbering]
{\Huge Section 2}
\end{frame}
\begin{frame}
Some more actual content here
\end{frame}
%and possibly on 20 more slides
%without specifying format for each of special slides
%every time
\end{document}
