- 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.
