When installing (or upgrading) FreeBSD 4.6 or greater (versions with XFree86 4.x), the startx program has a line "-nolisten tcp" which causes things like opening X apps remotely and displaying them on your local X server to not work. I couldn't find any docs on this, so please point it out if I just missed it. Fix: Either comment out the 'listen_tcp="-nolisten tcp"' line in /usr/X11R6/bin/startx, or remove the -nolisten tcp. Here's a quick paragraph for the handbook to cover this. I'm not sure if this is the exact page to put it on, but it might be ok. How-To-Repeat: Install/upgrade to 4.6(.2) with XFree86 installed. Run startx to start your X server. Log in to a remote machine, and try to run xcalc (or any X program) and have it display on your local machine. > --- chapter.sgml Wed Aug 21 17:13:25 2002

It's not a good thing to tell people to change files installed by
ports/packages, it will lead to problems during "desinstallation" and/or
upgrade.
That option can be given to startx on the command line as documented in
startx(1).
I don't think, it should be in the Handbook, but maybe in the FAQ, and
also something about using "ssh -X" too would be great :)

The FAQ seems like an appropriate place, and I agree with the "don't edit files
installed by ports/packages" for the most part. It definitely needs to be
documented somewhere, since there are posts on various groups asking the
question, and rarely an answer.
I'll try to whip up a FAQ piece for it.
