I ran into a strange problem today. A Beamer file I often use for my presentation does not compile any more on my Windows machine since Lyx (v2.1.3) says it cannot find the graphic files I use for the logo. Moving them to the .lyx file directory doe not fix the problem, but commenting the \logo instruction does.
The even stranger thing is that using File / Export / Latex (pfdLatex) on my Windows machine and then running "pdfLatex test.tex" works correctly!
Gilles, I know less than nothing about windoze since I stopped using it in 1997. But, I can report that lyx/beamer documents on linux, lyx/knitr documents, and PSTricks graphics all compile using pdflatex when they will not preview using dvips. This makes sense when we think about it: if the documents are intended to result in PDF files, then the driver should be pdxlinux. But, the preview using ctrl-p is in PostScript, not PDF format and other than regular text/graphics documents in LyX might not properly display. Avoid the preview and look only at the pdxlatex-compiled output. Rich
