I know this is an older thread, but I'm having this problem with Linux Mint 17 (based on Ubuntu 14.04). OpenLP cannot detect LibreOffice Impress. Settings -> Presentations shows a grayed-out "Impress (unavailable)". This is with the LibreOffice that comes with Ubuntu 14.04/Linux Mint 17, and OpenLP 2.0.4. I do have soffice at /usr/bin. In another similar thread, it was mentioned that python-uno was needed. However, that package does not exist. Any suggestions?<br>
