Running grass through Xwindows on a Solaris Server?

[Will Stafford]

Hi guys
With respect to GRASS through a PC XSERVER this is how we have it set up

We moved away from XVision to Goglobal because of cost differences and in my
opinion there is a real speed increase in the display time using goglobsal
verses xvision.

I have been running Grass across a t-1 line for several hours and found it
just slightly slower than a local machine.
My station and the server were 450 km a part.

The only unquie thing we had to do was setting golgobal host on the sun to
use XDM so that we could choose which desktop we wanted.
Grass works best with openwindows verses CDE.  In CDE the colours go wacko
when displaying a map. ( I know its colour map problem)

The other part would be that each student would need to have there own login
so that the grass single user lock can be worked around.

(anyone please correct me if the following is not correct!)
Rob,
Like the other responses, I would say that this presents no problems. We
have used Hummingbird's eXceedNT in the past, and currently
use StatNet's X-Win32 (they have a good multi-license discount) in
conjunction with the Tera Term terminal emulator (freebie, I think, nice
UNIX to Windows compatibility).

However, to the best of my knowledge, it is not possible to run the NVIZ
module through these products. The problem is that X-Windows is a
client-side product, and the Mesa graphics library necessary for the
NVIZ graphics would therefore have to be on the client. I don't know of
a way to do this with an X emulator. That's the only limitation to using
GRASS in this manner that I know of.

Cheers,
