How can I make a slide show run in a continuous loop?
First, all the transitions and animations in the slide show must be automatic. When that is done, do the following to have the slides loop continuously:
- Select ▸ in the main menu bar;
- Under Type, select the Auto radio button;
- Set the time for the desired interval between the last slide and the return to the first slide.
- The screen will be black during this interval. If you wish to display the LibreOffice logo on the black screen, check the Show logo option;
- Confirm with OK.
