this is probably a problem with CLX rather than with the motifd (CMUCL's
Motif support uses CLX as well as the platform's Motif libraries). I
expect that you will see the same error if you say
(require :clx)
(ext:open-clx-display)
It is possible that Fedora have switched to a new format for
authorization cookies (likely XDM-AUTHORIZATION-1 instead of
MIT-MAGIC-COOKIE-1); the output of "xauth list" should tell you. CMUCL's
CLX does not know how to handle this new format, so won't be able to
connect to your display.
If this is indeed the problem, a temporary workaround would be to
authorize all connections to your display from localhost:
xhost +localhost
