i suppose that technically Kephal is correct: it's emitting the signal when 
the number of screens has changed. however, i do agree with you that it's 
unintuitive that it does so when the screen hasn't actually "taken effect" 
yet. it seems that the Kephal::Screen itself is set up properly (has the right 
size, e.g.) but that Kephal::ScreenUtils::desktopGeometry() isn't correct? 
desktopGeometry is just a call to QDesktopWidget::geometry() ... so Kephal is, 
at that moment, in an inconsistent state.

i wonder if simply delaying the emitting of the screenAdded signal in Kephal 
would be enough to give desktopGeometry() enough time to "catch up".
