  - There may be a problem with the DISPLAY variable or Xwindows
    permissions. See the previous question.

  - You may be trying to display on a non-SGI machine which doesn't
    support GL/DGL.  Note that DGL is for running GL programs remotely,
    not OpenGL programs.  OpenGL programs run remotely via the 
    GLX X server extension.

  - DGL may be disabled in /etc/services and/or /etc/inetd.conf. The
    former file should have a line reading

      sgi-dgl         5232/tcp

    and the latter should have a line reading

      sgi-dgl stream  tcp   nowait  root   /usr/etc/dgld  dgld -IM -tDGLTSOCKET

    If either is commented out, remove the comment.

  - You may be trying to display on a machine with a much older version
    of IRIX. Try another machine with a newer IRIX.

  An article in the Jan/Feb 1993 Pipeline describes the above in great
  detail.
