"Gtk-WARNING cannot open display" from ssh

I am trying to do something on another computer through ssh and I keep getting this:
Code:
"(gedit:6169): Gtk-WARNING **: cannot open display:"

I have googled the interweb and this forum and found many posts but nothing seems to work. I have freshly installed Ubuntu 8.10 with updates on the machine and I have a KVM connected but, the screen just flashes on and off, mostly off, so it is unusable that way (Nvidia GTX 260, Asus M4A79T Deluxe). I have had it running perfectly under Ubuntu 9.04 without the blinking but am trying to do folding@home gpu2 under wine and was unsuccessful with 9.04 therefore I'm going to try 8.10, as the instructions use, but am doing it from my Mac Pro with ssh and getting that warning.

It does work on another computer (I get past this point) though there are other issues with that one.

GNOME-SSH-ASKPASS(1)					      General Commands Manual					      GNOME-SSH-ASKPASS(1)

NAME
gnome-ssh-askpass - prompts a user for a passphrase using GNOME SYNOPSIS
gnome-ssh-askpass DESCRIPTION
gnome-ssh-askpass is a GNOME-based passphrase dialog for use with OpenSSH. It is intended to be called by the ssh-add(1) program and not invoked directly. It allows ssh-add(1) to obtain a passphrase from a user, even if not connected to a terminal (assuming that an X display is available). This happens automatically in the case where ssh-add is invoked from one's ~/.xsession or as one of the GNOME startup pro- grams, for example. In order to be called automatically by ssh-add, gnome-ssh-askpass should be installed as /usr/bin/ssh-askpass. ENVIRONMENT VARIABLES
The following environment variables are recognized: GNOME_SSH_ASKPASS_GRAB_SERVER Causes gnome-ssh-askpass to grab the X server before asking for a passphrase. GNOME_SSH_ASKPASS_GRAB_POINTER Causes gnome-ssh-askpass to grab the mouse pointer using gdk_pointer_grab() before asking for a passphrase. Regardless of whether either of these environment variables is set, gnome-ssh-askpass will grab the keyboard using gdk_keyboard_grab(). AUTHOR
This manual page was written by Colin Watson <cjwatson@debian.org> for the Debian system (but may be used by others). It was based on that for x11-ssh-askpass by Philip Hands. GNOME-SSH-ASKPASS(1)
