[Tex/LaTex] How not to show subsection navigation bullets in the metropolis theme

beamerbeamer-metropolissectioning

I have two questions

I am using the metropolis theme with a section indicator as suggested by samcarter (Adding section indicator to Metropolis theme?). But I don't want to show subsection bullet dots as I have many subsections and each dot for each frame of the subsections will overflow. So I want to show only section indicators.
Also I want to put the section indicator at the bottom of frame instead of at the top.

\documentclass{beamer}

\usetheme{metropolis}

\setbeamertemplate{mini frame}{}
\setbeamertemplate{mini frame in current section}{}
\setbeamertemplate{mini frame in current subsection}{}

\makeatletter
\setbeamertemplate{footline}{%
  \begin{beamercolorbox}[colsep=1.5pt]{upper separation line head}
  \end{beamercolorbox}
  \begin{beamercolorbox}{section in head/foot}
    \vskip2pt\insertnavigation{\paperwidth}\vskip-2pt
  \end{beamercolorbox}%
  \begin{beamercolorbox}[colsep=1.5pt]{lower separation line head}
  \end{beamercolorbox}
}
\makeatother

\setbeamercolor{section in head/foot}{fg=normal text.bg, bg=structure.fg}

\begin{document}

\section{section 1}
\subsection{section name}
\begin{frame}
\frametitle{blub}
    abc
\end{frame} 
\begin{frame}
\frametitle{blub}
    abc
\end{frame} 

\section{section 2}
\begin{frame}
\frametitle{blub}
    abc
\end{frame} 

\section{section 3}
\begin{frame}
\frametitle{blub}
    abc
\end{frame}     

\end{document}

Second solution including framenumbers

\documentclass{beamer}

\usetheme{metropolis}

\setbeamertemplate{mini frame}{}
\setbeamertemplate{mini frame in current section}{}
\setbeamertemplate{mini frame in current subsection}{}

\makeatletter
\setbeamertemplate{footline}{%
  \begin{beamercolorbox}[wd=\textwidth, sep=3ex]{footline}%
    \usebeamerfont{page number in head/foot}%
    \usebeamertemplate*{frame footer}
    \hfill%
    \usebeamertemplate*{frame numbering}
  \end{beamercolorbox}%

  \begin{beamercolorbox}[colsep=1.5pt]{upper separation line head}
  \end{beamercolorbox}
  \begin{beamercolorbox}{section in head/foot}
    \vskip2pt\insertnavigation{\paperwidth}\vskip-2pt
  \end{beamercolorbox}%
  \begin{beamercolorbox}[colsep=1.5pt]{lower separation line head}
  \end{beamercolorbox}
}
\makeatother

\setbeamercolor{section in head/foot}{fg=normal text.bg, bg=structure.fg}

\begin{document}

\section{section 1}
\subsection{section name}
\begin{frame}
\frametitle{blub}
    abc
\end{frame} 
\begin{frame}
\frametitle{blub}
    abc
\end{frame} 

\section{section 2}
\begin{frame}
\frametitle{blub}
    abc
\end{frame} 

\section{section 3}
\begin{frame}
\frametitle{blub}
    abc
\end{frame}     

\end{document}

[Tex/LaTex] Mini frame navigation not drawn correctly

The problem here is that the outer theme smoothbars uses the beamer option compress in order to get the mini frames into one single line, while miniframes doesn't do that by default. So in order to remove the spurious space, you need to activate this compression, which can be done by saying

\beamer@compresstrue

in beamerthemeM21.sty (enclosed in \makeatletter ... \makeatother, of course).

BTW: You don't need to use \setcounter{subsection}{1} in each section as in your MWE, doing this once (e. g. in your theme file) is enough.

So the corrected beamerthemeM21.sty looks like this:

\usepackage{remreset}
\makeatletter
\@removefromreset{subsection}{section}
\beamer@compresstrue
\makeatother
\setcounter{subsection}{1}

\mode<presentation>
\setbeamercovered{transparent}

\mode<all>
\useoutertheme[subsection=false]{miniframes}

\setbeamertemplate{navigation symbols}{}

[Tex/LaTex] How to remove some pages from the navigation bullets in Beamer

The mini frames are generated using the \beamer@framepages entries in the auxiliary .nav file. If you remove these for certain frames, they don't appear in the navigation¹. To do so, you have to patch the \beamer@writeslidentry macro responsible for writing the commands to the .nav file:

\makeatletter
\let\beamer@writeslidentry@miniframeson=\beamer@writeslidentry
\def\beamer@writeslidentry@miniframesoff{%
  \expandafter\beamer@ifempty\expandafter{\beamer@framestartpage}{}% does not happen normally
  {%else
    % removed \addtocontents commands
    \clearpage\beamer@notesactions%
  }
}
\newcommand*{\miniframeson}{\let\beamer@writeslidentry=\beamer@writeslidentry@miniframeson}
\newcommand*{\miniframesoff}{\let\beamer@writeslidentry=\beamer@writeslidentry@miniframesoff}
\makeatother

Include this code in your document, then you can switch between the original implementation and the modified one not generating any mini frames by using \miniframeson and \miniframesoff.

¹This may, however, have some unwanted consequences I'm not aware of!

Full example code:

\documentclass[compress]{beamer}
\useoutertheme[subsection=false]{miniframes}
\makeatletter
\let\beamer@writeslidentry@miniframeson=\beamer@writeslidentry
\def\beamer@writeslidentry@miniframesoff{%
  \expandafter\beamer@ifempty\expandafter{\beamer@framestartpage}{}% does not happen normally
  {%else
    % removed \addtocontents commands
    \clearpage\beamer@notesactions%
  }
}
\newcommand*{\miniframeson}{\let\beamer@writeslidentry=\beamer@writeslidentry@miniframeson}
\newcommand*{\miniframesoff}{\let\beamer@writeslidentry=\beamer@writeslidentry@miniframesoff}
\makeatother
\begin{document}
\section{S1}
\subsection{SS1}
\frame{1}
\miniframesoff
\frame{2}
\miniframeson
\frame{3}
\subsection{SS2}
