I had a similar issue, with the exact error message, while using 'xrandr' to enable dual-screen mode. For some reason, it seems, like 'X/randr' "loses" the information about its *primary* screen. I hope I remember it correctly - this happened a while ago on another machine - will try to replicate it on another laptop this evening (GMT). The odd behaviour, which I just described, could have been observed "in more detail" by one of the '*randr' GUI tools (not sure whether it was arandr), i.e. it would show that there's no primary output and you couldn't arrange your outputs properly. Using 'xrandr' commands with '--output' seems to have "solved" the issue for me. All worked fine with 5.5 but "broke" with 5.6. I hadn't reported a bug as I though it might have been an intended changed, i.e. '--output' now required. Does this sound at all similar to your issue and does using '--output' solve it for you?
