Hi, The theme is called "CambridgeUS" (the second "S" is uppercase). BTW, the latex-beamer package is not necessary to get Beamer working; I use Beamer regularly and I don't have that package installed. Using pacman -Qo /usr/share/texmf-dist/tex/latex/beamer I get that it's installed by texlive-core.
