Change all text fonts in Libreoffice Impress presentation?

Question

Anyone got any idea how to change the font of all text boxes in an Impress presentation? Applying a Master slide doesn't appear to have any useful effect.

Answer 1

Press F11, you will see a style dialog. Right click on "Default", and change the font.

Answer 2

first, you can use font substitution in LibreOffice settings, however, this will have only effect on your computer. I also faced this problem and as I remember, I did some experiments with the XML files inside the OpenDocument file. I extracted it using 7zip and then used PSPad editor to search and replace the font names in the files. It is a longer time ago so I do not remember the exact procedure. :-)
