How do I get LMR or CMR math font in beamer class in LyX? In the document settings when I change the font only the text is affected and not the equations.

  • bemear uses CM by default: you must be making some font changes to get a different font in the first place.

  • @JosephWright I already tried the default settings. I still don't get CMR

  • Ah, you want the serif option. I'll post an answer, but as it's for 'standard' LaTeX there may be more to say for Lyx.

into the "Document->Setting->LaTeX preamble", then beamer didn't change anything in the math fonts

  • Awesome! That worked perfectly. Thanks @Herbert.
