This is an X authentication error. This indicates that
$HOME/.Xauthority (or the file referenced by $XAUTHORITY, if that is
set) is, in some sense, invalid.

One common reason for this is if $HOME isn't set correctly. Try
running "xauth list" to view the list of authentication credentials
which are available to Xlib.
