  Speaking about krfb, after https://phabricator.kde.org/D5211 X11 plugin (and `XGetImage` code) does not exist anymore. And krfb is aware of having multiple screens, but it shares only primary screen area:
  
  - xcb plugin: https://cgit.kde.org/krfb.git/tree/framebuffers/xcb/xcb_framebuffer.cpp#n171
  - qt plugin: https://cgit.kde.org/krfb.git/tree/framebuffers/qt/qtframebuffer.cpp#n81
  
  I cannot imagine how VNC server application can properly serve multiple monitors at once, especially if they have different resolutions (merge them into one big image covering all monitors at once, with black border around the smaller one?). So I think if krfb will ever support multiple monitors explicitly, there will be a combo box to select which screen to share.
  
  Do you think other screen recording applications will need to capture several monitors at once?
