Steps to Reproduce:
1. Take a machine with 2 monitors and put the monitors in clone mode
2. Start a presentation
3. Notice impress is showing the "presenter screen" rather then the slides, indicating it thinks there
are >= 2 heads, and since there is actually one the actual slides get shown nowhere ...
impress is showing the "presenter screen" rather then the slides
Impress sees this as a single monitor setup and shows just the slides
p.s. libreoffice version:
Created attachment 580165 [details]
a shot at this (does not work :-)
Eh, I felt into the most common STL trap...
should be fixed in libreoffice-18.104.22.168-4.fc17
