Thanks!  The messages one gets on attaching are somewhat scary:

  failed to setup mmap: No module named ctypes
  '['setxkbmap', '-query']' failed with exit code 255

  the server will try to guess your keyboard mapping, which works
  reasonably well in most cases however, upgrading 'setxkbmap' to a
  version that supports the '-query' parameter is preferred

  glib is missing, cannot set the application name, please install glib's
  python bindings: No module named glib

but it does seem to work.
