Getting Xauthority properly setup is not difficult. The general picture
of what's going on is:
1) Some program generates a magic cookie (arbitrary string) and writes
this to a file.
2) The name of this file (often ~/.Xauthority) is passed to the X
3) The X server writes an entry for the DISPLAY into your
4) Xlib reads ~/.Xauthority when you create a window, and passes the
cookie value back to the X server.
See your X11 init and control scripts (usually down under /etc/X11) for
details. This is no hard stuff. To (re)synchronise the session key
xauth nlist $DISPLAY | rsh other.host xauth nmerge -
Or just use SSH's X11 forwarding.
