With the help of Alex and Michel, I think I tracked this down to the
incompatible Xinerama implementations between Zaphod and XRandR.
While each of them works fine in isolation, once you enable Zaphod,
XRandR simply won't emulate Xinerama.

My window manager (awesome) apparently only has Xinerama support,
not XRandR support.
