ssh and X display forwarding

[Alan Chandler <alan@chandlerfamily.org.uk>]

My desktop at home runs KDE.

I ssh into my server, but when I get there the DISPLAY variable is not 
set up, meaning I can't run graphical programs.

On my desktop

/etc/kde3/kdm/kdmrc has the ServerArgsLocal=-nolisten TCP commented out
/etc/ssh/ssh_config specifies X11Forwarding as yes
/etc/ssh/sshd_config on the server also allows X11Forwarding

I have run xhost during start up, so the server is an allowed connector 
to my display.

What else to make it work - and how do I find out (ie which logs should 
I look at) why it isn't
