X-Terminal over SSH Woes

[Mark Phillips]

I cannot figure out what is wrong. Everything I have read on the net and in 
O'Rreilly's SSH book say I am doing it right, but it doesn't work!

Machine - monkey
Debian stable
/etc/ssh/ssh_config has
   ForwardX11 yes
   ForwardX11Trusted no

Machine - stingray
Debian stable
kde desktop is running
/etc/ssh/ssh_config has
   ForwardX11 yes
   ForwardX11Trusted no

I can ssh from monkey to stingray (and vice versa)

When I try ssh -X stingray from monkey, I get Error: Can't open display.

In debug mode, I see the following:
debug1: Authentication succeeded (keyboard-interactive).
debug1: channel 0: new [client-session]
debug1: Entering interactive session.
debug1: Requesting X11 forwarding with authentication spoofing.
Linux stingray 2.6.8-2-386 #1 Tue Aug 16 12:46:35 UTC 2005 i686 GNU/Linux

mark at stingray:~$ echo $DISPLAY

mark at stingray:~$ xeyes
Error: Can't open display:
mark at stingray:~$ exit
debug1: client_input_channel_req: channel 0 rtype exit-status reply 0
logout
debug1: channel 0: free: client-session, nchannels 1
Connection to stingray closed.
debug1: Transferred: stdin 0, stdout 0, stderr 32 bytes in 87.1 seconds
debug1: Bytes per second: stdin 0.0, stdout 0.0, stderr 0.4
debug1: Exit status 1

FWIW, I can do "X -query stingray" from monkey and get the gdm login
and my kde desktop from stingray to monkey.
 
What am I doing wrong?

Thanks!
