It won't work for me as it is only picking up the HDMI ports:
I suspect also there might be a need for Jack packages and in view of how screwy Jack became it wasn't long before most distros ditched Jack Audio - ALSA feels like it is in the same position that Betamax was to VHS cf. Pulse - Pulse is the worst audio system ever but it has become embedded not just in Linux but I read somewhere that it is embedded in audio for the motor vehicle industry so it is hard to remove it!
On a side note, Q4OS is based on Debian - and shutter is still available - superior to spectacle because it captures menu drop-downs, spectacle doesn't/can't.
