Hi Jerry,

I vaguely recall, from years ago in days of old when MIT-MAGIC-COOKIEs
filled the air, that I had a similar error message and tracked it down to
bad permissions on a ~/.Xauthority file, or something like that.  I think
it was caused by trying to do a sudo connection, which made that file owned
by root, after which my regular user couldn't use it anymore.

Good luck,
