If you setup X11 forwarding in PuTTY, then double-click on a saved putty session, it will clear out the X11 forwarding and use the settings from the saved session (no X forwarding). If X forwarding is properly enabled, you should not have to set the DISPLAY variable on the remote side.
You don't need the X server or anything else on the remote server. Default firewall will have no effect either. Also, make sure to reload sshd after changing the settings (service sshd reload).
I've tried both cleared and set X11 forwarding checkbox in PuTTY, both as root and non-root and only get:
$ xterm xterm Xt error: Can't open display: xterm: DISPLAY is not set
In the Xming log nothing happens at all (attached below).
Is maybe WinXP firewall inbetween, do I need to open some port? (Xming asked me to do that during its startup, and I did so - clicked the "Unblock" button)
Is something in your .profile or .bashrc clearing your DISPLAY variable? When I log in with putty with the X forwarding box checked I get a DISPLAY variable set automatically (you can see it with 'env') that isn't set when I don't check the box.
