Once we agree on this, I will also edit the readme and the website accordingly.

This will Fix #761

@deltragon Could you confirm whether xprintidle does in xorg whatever pywayland does in wayland?

Or do they have different functions?

Yes, that is correct.

Oh, I just saw the python-gi dependency - we do also need that, but it might also be called something like python-gobject. That's not a new thing, but I added it to the readme because someone was missing it.

It isn't, technically - however, the way we currently import it makes it required on Wayland too. I'll send a PR to fix that (and move it to the Suggests section as well).
