Sounds like a similar problem with the driver then, in it
not supporting XRandR output properties, even though
it says it's XRandR 1.2. You should really complain
to whoever provided the driver. Working around it
by making the error non-fatal involves changing spactro/dispwin.c
to change the null_error_handler() routine to set a global
when it gets triggered, then in set_X11_atom() wrapping the call
to XRRChangeOutputProperty() in a call to XSetErrorHandler(null_error_handler)
and XSetErrorHandler(NULL) afterwards, checking the global to issue
a warning that the XRRChangeOutputProperty() call failed, rather than
fatal erroring. If it helps I can post a copy of my current dispwin.c
for you to refer to.
