I followed the installation process for Xaringan explained by Tim Mastny. Everything worked smoothly and I could produce my first slideshow.
To make the slides work offline, I followed the tips by Yihui Xie. The download with xaringan::summon_remark() went fine and generated the libs folder in my project directory with the file remark-latest.min.js in it. But when I added the chakra option chakra: libs/remark-latest.min.js to the YAML header as describe in the Xaringan slideshow documenation, and called serve_site(), the slideshow did not work anymore.
Instead of the previous working slideshow I got a small window on the left top of my screen which contains the source text of my slideshow. I have seen this window in other occassions as well. For instance in some links from the remark.js website to demo slideshows, e.g. here.
I installed a complete new blogdown website with the Xmin theme and did the installation procedure from scratch. I used the R Markdown "Nina Presentation" template and added just the one chakra line. I received the same result. Just the small window.
I used Google Chrome but tested also with Safari and Firefox with the same result. Has anyone any idea what could be the problem or what I could try next?

Found the problem: you summoned remark.js to libs/ in your blogdown project's root directory. Instead, you should summon remark.js to static/slide/libs/ using:
xaringan::summon_remark(to = "static/slide/libs")
Explaination: Hugo copies all files under "static/" to the root of the compiled website.
Make sure libs/ sits together with your xaringan source Rmd somewhere under static/ subdirectory, like yours: static/slide/libs, so that the xaringan can find files they need.
And that remark-latest-min.js should be in static/slide/libs/ too.
