is it a black input bar that doesn't appear to do anything?
(it probably does work -- did you try typing blind?)

the fix is to update /usr/X11/xdm/Xresources file -- it has
new required entries.  i'm going to work on making this less
awful when it isn't updated, but i've been busy working on
the Mesa18 update :-)

postinstall is not yet capable of properly updating it or
really suggesting what you need to do, so that would be the
first step, but perhaps also making /etc/rc.d/xdm fail to
run if the new entries are missing would be good too.

thanks.
