Your IDL is trying to connect to an X windows display that doesn't exist. The easiest way is to tell IDL that your display doesn't exist. Do this before you execute IDL: (pick whichever line matches your shell)
unsetenv DISPLAY # this is for csh or tcsh
unset DISPLAY # this is for bash or sh
And then to be sure, within IDL, tell IDL to use a different device...
set_plot, 'Z'
Here 'Z' means the Z-buffer, which doesn't try to connect to any screen.
