When it comes to presenting on a Linux PC, the powerpoint format is not an option. Neither is Openoffice/Libreoffice for me. Designing presentations with Openoffice/Libreoffice can be quite frustrating and results in incompatibilities with other presentation slide generators like Powerpoint.
The only format that can guarantee consistency of your presentation across devices is pdf.
When you want to present a pdf, you can just open it in any pdf viewer, go fullscreen and mirror the display. But this simple setup is still far away from the comfort of Libreoffice/Openoffice/Powerpoint presentation mode. Wouldn’t it be nice to combine the reliability of pdf with the flexibility of the presentation mode found in Libreoffice/Openoffice/Powerpoint?
My requirements for a pdf presenter software are as follows:
-An extended desktop setup, with one screen showing the current slide and the oder screen showing a preview of the upcoming slides.
-Be able to show notes and annotations that are not visible on the main screen. Notes should be easy to modify.
-Easy navigation between the slides and an overview of the complete presentation with slide thumbnails.
There seem to be very few pieces of software out there that support those concepts. One that fits my needs is https://pdfpc.github.io/ .
The notes are written to a plaintext file and can be edited inside the application while in presentation mode or with any text editor.
It comes with many useful features that can be found on the home page and which I will not reiterate here.
The weak spots of pdfpc are in my opinion:
-Initial rendering of the thumbnails can take some time
-Escape ends the presentation, escape also exits annotation mode. Visually it is not always clear if annotation mode is still running and you might unintentionally end your presentation.
Apart from that it is a very good presenter software that I can fully recommend to anyone doing presentations in pdf format.
