Setting the DISPLAY environment variableWhen you connect via SSH, your X11 environment should be automatically configured. If it is not, you may have to connect using the -X (upper-case X) or -Y (upper-case Y) option on the ssh command line.
If your X11 display still does not work, check that the DISPLAY environment variable has been set properly. This variable is used by the X application to determine the internet address of your local screen. You can check by typing this command at the NERSC machine prompt:
<div class="terminal"> %echo $DISPLAY
