I tried to use the following codes to insert logo in to my beamer, but they dont work with LyX.

If you have a file called "institution-logo-filename.xxx", where xxx is a graphic format that can be processed by latex or pdflatex, resp., then you can add a logo by uncommenting the following:


I end up by using \titlegraphic{\includegraphics{uni-logo-filename}}

How to change the size of the institutional logo on LyX/beamer using above codes?

    Welcome to TeX.sx! Please add a minimal working example (MWE) that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting with \documentclass{...} and ending with \end{document}.

  • @Jubobs For LyX, it is sometimes not easy to provide compilable code starting with \documentclass{...} and ending with \end{document} because LyX is not a LaTeX editor but a document processor that can generate LaTeX. -- In this case, it would be helpful to mention that the LyX template "beamer-conference-ornate-20min.lyx" was used (probably)...
