If you have an iPhone or Android device you can remotely control presentations from your smartphone using a mobile app called
Lib re Office Impress Remote. Once you’ve installed the a pp, launch Lib re Office Impress and head to Tools> Options. Then navigate to LibreOffice Impress>General and then ensure that the Enable remote control box is checked. This enables inbound access from your smartphone and adds useful menu entries you will need later.
Next you should pair your smartphone with your workstation, and the fully supported way of doing this is by using Bluetooth. If you’re using a desktop rather than a laptop you may need to add an extra USB dongle for this to work. To pair them, enable Bluetooth on both devices, make them visible to each other and then use your distro’s settings panel to add your smartphone as a device the system recognises. There’s also experimental support for Wi-Fi pairing, which you can enable from Tools> Options and then Lib re Office> Advanced. Note that checking the box for Enable experimental features may lead to strange behaviour elsewhere in your office suite.
Once both devices are paired you can either connect from the mobile a pp itself or from inside Lib re Office Impress via Slide Show>Impress Remote.
