FWIW, I've seen this a few times (with dispwin, not dispcal).  I think
it happens when I hotplug a new display but don't configure it.  That
is:

1. Start with only laptop panel connected.  dispwin works.
2. Plug in VGA cable.  dispwin fails.
3. xrandr --output VGA1 --right-of LVDS1 --auto.  dispwin works again.

I can't test that right now (no monitor to hotplug), but I can give it
a try later on at work.
