Autoclose and pptx Transition.

What I’m trying to do is to have an interface, that I am developing, open a pp file, Test123.pptx or ppsx through a command line call libreoffice – show /home/user/test123.pptx. My app works on a linux box, but my users will edit the pptx file with Office 2010 then FTP it to the box. Then the presentation should run every hour on that box in the lunch rooms.

The 2 problems I have is that if I set the slide transition every x seconds in Office 2010, they don’t work on libreoffice… The other problem is that it doesn’t auto close… It stays at black page and the user has to click to close… There will be no users there…
