In sync mode, there isn't a lot going on that the error could be caused by.
By any chance could there have been an old display server in use that
doesn't support all the modern RandR extensions?

John, could you try "xrandr -v" against the same display where you were
running Emacs? If it says the server supports version 1.3, then the
RRGetScreenResourcesCurrent request (the one in use at xfns.c:4266) should
be supported, as I understand it.

If there are servers out there still supporting only 1.2, then we may need
to check the server version before issuing that request.

Ken
