X forwarding over SSH

Hi all,
I've been using my Pi with archlinux and ssh'ing into it remotely (with ssh -X or ssh -Y for X11 forwarding), but I've been unable to get X forwarding to work so far. I have X running, and it's created a :0 display, but when I run a program with DISPLAY=:0 <program> it just sits there, sometimes giving a warning message.

For example, running emacs:
DISPLAY=:0 emacs

GLib-GIO-Message: Using the 'memory' GSettings backend. Your settings will not be saved or shared with other applications.

But after that nothing happens. I don't get an emacs window, and if I ctrl C it I get:
(emacs:1747) GConf-WARNING ** : Got disconnected from DBus.

Are the programs trying to pop up on the actual Pi display instead of my local machine? If so, what's the fix?

What happens if you enter the command?

ssh -X raspberry-name-or-address xeyes


xhost +

on your local machine make any difference?

Nevermind, I figured it out. sshd wasn't configured correctly.

For those having the same problem:
In /etc/ssh/sshd_config
make sure X11ForwardingEnable and X11UseLocalhost are set to yes.

I use cygwin how terminal X Window
you make sure execute Cygwin-X -> XWin Server program, then login with ssh:
# ssh -Y root@192.168.1.xxx

then run any X program, for example the visual debuger (ddd):
# ddd

The main window of ddd appears in MSWindows.
