[daip] TV display

Are you sure it isn't there but minimized or iconified?  The listing
below looks quite normal.  

We have AIPS running on RedHat 9, Red Hat Enterprise Linux
(Workstation), and other Linux systems so presumably your environment
will be very similar to ours.

So far so good.

One local disk, so AIPS should be able to start ok.

No problem here.

If all else fails (and read on before trying this), you can try using
a unix ("local") TV instead by starting it with:

      aips tv=local

but as I said, read on first.

Good.

Hmm.  "user 500?"  Is this your login name, i.e. if you type "id" and
"whoami" on the unix command line, what do they show?  This may be a red
herring.  Another thing that will help (us, not you) is the output of
"ps aux | grep TVSERV" as the script is grabbing that and possibly
mis-interpreting it.

> XASERVERS: Start XAS on localhost, DISPLAY :0

That's good I think, but there should be additional messages here.  Do
you know the depth of your screen (8, 16, 24, 32 planes)?  You can
figure this out via the output of xdpyinfo; the default visual should be
capable of showing 24 or more planes, e.g.:

  ...
  default visual id:  0x21
  visual:
    visual id:    0x21
    class:    TrueColor
    depth:    24 planes
  ...

Fair enough; there should be one xterm or similar window on the screen
with the message server running, and another minimized or iconified with
the tek server running in it.

Presumably you get the "> " prompt here and can get simple things like
"print 2 + 2" and "go disku" to work?

I would give the whole thing another try, by exiting the AIPS session
with "kleenex" to get rid of any existing servers, and start over.  Then
remember to look for the TV window iconified, or minimized (if in GNOME
or KDE, check the panel on the bottom of the screen).  If that still
shows no TV, exit with "kleenex" again, and try "aips tv=local".

Hope some of this helps.
