Emerging latex-beamer-3.0 or 3.0.1 doesn't intall the proper layout file in /usr/share/lyx/layout (if lyx is present) but put it into /usr/share/doc/lyx/layouts, so it doesn't show up in the proper document selection window. Reproducible: Always Steps to Reproduce: 1. 2. 3.
Created attachment 68666 [details, diff] add lyx support to latex-beamer This patch installs the lyx-files in the appropriate directories. I kept the test for installed lyx. This is not really nice, it would be better to add a use flag lyx.
Fixed in 3.06-r1. Thanks for reporting and thanks for the patch!
