 The issue is basically that as we presently distribute xdm, it won't
 interoperate properly with some modern X applications, because the
 authorization mechanism it defaults to doesn't work. This was surprising
 to me as well (I don't use xdm or any other display manager), as the
 error messages aren't clear here about what's happening. I was able to
 reproduce this myself and test the configuration tweak.
 
 Other BSDs and Linux distros dealt with this years ago; e.g., FreeBSD
 changed the default in the configuration to be what I suggested, Debian
 changed xdm's compilation settings to fundamentally disable the xdm
 authorization method, etc. I feel NetBSD should do something of the sort
 as well, but that probably requires discussion among developers. So, for
 now, I've adjusted chapter 9.8 in the guide to add this detail.
 
 Thanks for using Xfce on NetBSD and for reporting this issue.
