This looks, as if your default display is not set. Try to start the
application with a  -display :0.0  option (does not work for some
xfce and gtk applications, that use different options) or set the
DISPLAY environment variable to :0.0.

If this were a permission problem you should get a message like:
X Server refused connection.
