I am using beamer to type slides. Recently, I reinstalled AucTeX and now the numbers don't look right. I use begin{enumerate}[1.] so that it will print 1., 2., etc. instead of the numbers with the circles around them. But, after the reinstallation, it is doing the circles, even for the exact same files where it was okay before even with TeXshop on a Mac.

My example code:

documentclass[12pt]{beamer}

  begin{enumerate}[1.]

    item La

    item La La

  end{enumerate}

end{document}

Don't use the enumerate package with beamer since it provides templates to set these things. Specifically, you're interested in the [default] template for enumerate item:

documentclass{beamer}



usetheme{Boadilla}

usecolortheme{seahorse}



begin{document}



begin{frame}

  begin{enumerate}

    item La

    item La La

  end{enumerate}



  setbeamertemplate{enumerate item}[default]



  begin{enumerate}

    item La

    item La La

  end{enumerate}

end{frame}



end{document}
