I don't know but I do have questions.  So maybe...  What is the output
of these commands?

    type xauth
    xauth info
    xauth list
    ls -ld ~/.Xauthority

And if that file is zero sized then does this help?

    xauth generate $DISPLAY

Bob

P.S. Examples showing possible output such as from here.

    rwp at torpid:~$ type xauth
    xauth is hashed (/usr/bin/xauth)
