I like using the Beamer Goettingen theme as it has a nice sidebar. I would like to remove this from occasional slides, so the text can go all the way across. However, while the [plain] option removes the side bar, the text still wraps as if the side bar were there (minimal worked example below). How do I get text to wrap across slide?
\documentclass{beamer}
\usetheme{Goettingen}
\usepackage{lipsum}
\usecolortheme{seahorse}
\begin{document}
\begin{frame}[plain]{title}
\lipsum
\end{frame}
\end{document}

geometrypackage for that. The idea is to use a\newgeometrybefore\begin{frame}and use\restoregeometryright after\end{frame}. Take a look atgeometrydocs. – cacamailg May 09 '13 at 12:01
