slide_numbers always True for slides2 theme (?)

[Stewori]

With slide_theme = 'slides2' I always get slide numbers like 2/15on the bottom right corner of every slide, except on title page.
I tried to set slide_numbers = False explicitly in conf.py without any effect. However it should default to False anyway, so it was expectable that there's more to it.

Is there a working way to turn it off? If there is no proper way, does someone know where I need to modify the source for this? At least roughly (maybe I can figure out then)?

I looked into the html and css source but cannot find the code responsible for the page number. It must be somewhere else.

It looks like this is defined in default.css as

/* line 147, ../scss/default.scss */
slides > slide:not(.nobackground):after {
  font-size: 12pt;
  content: attr(data-slide-num) "/" attr(data-total-slides);
  position: absolute;
  bottom: 20px;
  right: 60px;
  line-height: 1.9;
}

However, overriding this css entry in a custom.css seems to have no effect. This used to work for other aspects of the slides.
The entry stems from default.scss:

    &:after {
      font-size: 12pt;
      content: attr(data-slide-num) '/' attr(data-total-slides);
      position: absolute;
      bottom: $slide-top-bottom-padding / 2;
      right: $slide-left-right-padding;
      line-height: 1.9;
    }

Maybe that needs to be overridden...?

If I directly modify _build/slides/_static/theme/css/default.css like this:

/* line 147, ../scss/default.scss */
  slides > slide:not(.nobackground):after {
  font-size: 12pt;
  /* content: attr(data-slide-num) "/" attr(data-total-slides); */
  position: absolute;
  bottom: 20px;
  right: 60px;
  line-height: 1.9;
}

I get actually rid of the slide numbers. But this does obviously not persist building. For now I helped myself with a shell script for building:

make slides
cp default.css _build/slides/_static/theme/css/default.css

having the modified default.css in the source folder.

Still, this should be properly fixed.
