I'm trying to setup my laptop (Dell D420) with Lubuntu 14.04 and Libreoffice 4.2 to show a slide presentation to a VGA projector. I used ARandR to make a screen layout where the laptop screen (resolution 1280x800) shows the left side of the desktop and the VGA projector (1024x768) the right side.
I tried a number of configurations and settings to no success except one that work partially: Going to Slide Show menu and Slide Show Settings I set Multiple Displays to All displays. In doing so I see the slide show on the projector but only the edition mode in the laptop screen. Trying the other settings for Multiple Displays will give:
Display 1: Console shows on the laptop screen but the slide show doesn't appear in the projector screen (instead it appears in the background of the laptop screen)
Display 2 (external display): Shows the console fully on the laptop screen but doesn't show the slide show in the projector.
Auto External (Display 2): Same as Display 2.
If I set ARandR to mirror the display only the console will be mirrored and not the slide show. Somebody could tell me a solution?
