I am making a beamer presentation with XeTeX, in which I am using Ilmenau theme. This theme has by default smoothbars as an outer theme. My problem that in a section's subsection, there are a lot of frames, which makes too many bullets in the header. How Can I remove/wrap those bullets from header to make the presentation look a bit more pretty.

\documentclass[slidestop,compress,10pt,xcolor=dvipsnames]{beamer}
\newcommand*\oldmacro{}%
\let\oldmacro\insertshorttitle%
\renewcommand*\insertshorttitle{%
  \oldmacro\hfill%
\insertframenumber\,/\,\inserttotalframenumber}
\setbeamertemplate{footline}[frame number] 
\setbeamertemplate{blocks}[rounded][shadow=true] 
\setbeamertemplate{navigation symbols}{} 
%\usepackage[cm-default]{fontspec}
%\setromanfont{GFS Neohellenic}
\mode<presentation>
\AtBeginSection[]
{
 \begin{frame}<beamer>
    \frametitle{Outline}
    \footnotesize{\tableofcontents[currentsection]}
  \end{frame}
}
\usetheme{Ilmenau}
%\useoutertheme[subsection=false]{smoothbars}%Beamer Outer Theme-circles on top

\begin{document}

\section{Results}

\subsection{First Subsection}
\frame{Frame 0}

\subsection{Long Subsection}
\frame{Frame 1}
\frame{Frame 2}
\frame{Frame 3}
\frame{Frame 4}
\frame{Frame 5}
\frame{Frame 6}

\subsection{Third Subsection}
\frame{Frame 7}

\end{document} 

My ugly output is

I was facing the same problem once(tex.stackexchange.com/questions/74846/…) and I was adviced to update/upgrade my MikTeX distribution. Which distro are you using? –  Thanos Feb 12 '13 at 5:56

I'm not quite sure what you want to achieve here: I don't see any overflow problems in your output, it's simply one bullet (they are called mini frames, BTW) for each slide of the subsection. Maybe you want only one mini frame per subsection? –  diabonas Feb 13 '13 at 18:58
    
@diabonas: Thank you very much for your citation! That was exactly what I needed! Instead of a comment, is it possible to add an answer in order to accept it? –  stergios Feb 14 '13 at 12:29

As a possible solution, you could consider to use the subsection title instead of a bullet for each frame. If this is prettier than the bullets is a matter of personal taste :). Here is what I've got:

Frames 1 to 6 highlight the Longest subsection title. The trick is to use the \insertsectionnavigationhorizontal and \insertsubsectionnavigationhorizontal instead of the \insertnavigation used by the mini frames theme. The only modification to your code is the definition of the headline beamer template. The code is adapted from the Mini frames outer theme that is what Ilmenau theme uses by default.

\setbeamertemplate{headline}{%
\begin{beamercolorbox}[colsep=1.5pt]{upper separation line head}
\end{beamercolorbox}
\begin{beamercolorbox}{section in head/foot}
    \vskip2pt\insertsectionnavigationhorizontal{\paperwidth}{}{\hskip0pt plus1filll}\vskip2pt
\end{beamercolorbox}%
\begin{beamercolorbox}[ht=10pt]{subsection in head/foot}%
    \vskip2pt\insertsubsectionnavigationhorizontal{\paperwidth}{}{\hskip0pt plus1filll}\vskip2pt
\end{beamercolorbox}%
\begin{beamercolorbox}[colsep=1.5pt]{lower separation line head}
\end{beamercolorbox}
}

Add this code after loading the Ilmenau theme, and before the \begin{document}. The \hskip0pt plus1filll is used to left-justify the section and subsection titles.

Thank you very much for your answer! The thing is that I actually want the bullet points to show up... diabonas provides a comment which links to a probable accepted solution tex.stackexchange.com/questions/64333/… –  stergios Feb 14 '13 at 12:33
