Problem with X11 Forwarding

Hello. I installed a Debian box, and its installed remotely. I need to boot up iceweasel from there to do a quick test.

I log on using:

ssh root@<IP> -X

I have modified the /etc/ssh/sshd_config file, and added the X11Forwarding yes flag

And yet I still get:

Error: cannot open display: :0

When I try to open iceweasel from the remote server.

How else can I attack this problem? Thanks!

What does the DISPLAY variable get set to on the remote side?
# 3  
root@<IP>:~# echo $DISPLAY



# 4  
The value of DISPLAY may be getting overridden, perhaps by a login script or somesuch.
# 5  
I really don't have any custom login scripts...

The box has little things installed.

It didn't have gnome. I tried installing gnome... I'm still getting the error.
# 6  
Are you sure of your syntax?

I would type: ssh -X root@<IP> ...
# 7  

Yes I am positive.

$ ssh -X root@<IP>
root@<IP>'s password: 
Linux <IP> 2.6.32-5-xen-amd64 #1 SMP Mon Jan 16 20:48:30 UTC 2012 x86_64
