LibreOffice Impress features non-functional/missing

[chaoscommander]

My installation of LibreOffice is missing features described in the official documentation or they don't work. I'm not sure if this is all of them, but these two I noticed so far:

There is no option to enable remote control. Documentation says it is supposed to be at Settings -> Impress, but it's simply not there, nor anywhere else.

The second one is more important right now: the presenter console doesn't recognize I have multiple displays. The system does. I can split my desktop, I can have it duplicated, use only one screen or the other etc., but when I click "Presentation Settings", the drop-down list for how to use multiple displays is disabled. I really need to use Presenter Console on my primary display while showing the slides on an external display. Any idea how I can make LibreOffice acknowledge the second display? This used to work on some previous version.

Here's my flags for libreoffice-bin:

as an alternative you may build libreoffice from the ebuild.

Rebuilt libreoffice from source, which added the Remote Control functionality, and then it seemed to be important to first connect and power on the secondary display before launching Impress, which solved the display issue.
