I've seen this sort of problem with other non-CMUCL lisp applications
running under the OpenWindows X server.  Are you using the OpenWindows
server?  Try doing an:

% xhost +

and see if it fixes the problem.  

This is just a guess, but it may be the case that OpenWindows treats
authorization for connections on unix domain sockets differently from
those on internet domain sockets.  Somebody with the CLX sources
should look at xlib:open-display to see that it opens the right kind
of socket to the server based on the state of the environment variable
DISPLAY and the arguments passed to it.
