"Can't write to client" basically means that the client process died,
so we can't send any events to it. This problem seem to be on the
client (that is the application, not the broadway daemon) side, so you
have to debug the client instead.

Having no idea of your particular problem I can still make a guess. It
is likely that your more complicated apps (like eclipse) is trying to
do something that is specific to the X11 backend, without actually
verifying that the active backend is X11 (or verifying and bailing
out).
