Unhappy Xorg upgrade

[Dan Allen]

Thanks to Robert for pointing out a few things to me.

I have run

     portupgrade -rf libxcb

and it rebuilt quite a few pieces that had not been rebuilt in the  
standard portupgrade that gave me X.org 7.4 in the first place.

After rebuilding firefox and a bunch of smaller libraries, my keyboard  
and mouse work, and so does firefox and my other apps.

Thanks to everyone else for emailing me with ideas and suggestions!
