Luca:
I apologise if I was not clear. My goal is the following: my new board
is running ucLinux. It is a VME board. It does not have its own display.
But it has a gigabit ethernet interface.
I want to run an app which will
popup a window on a remote machine, either a regular Linux box or
Windows. I do not care, whether the remote machine is Linux or Windows.
Can be either.
AFAIK you can't 'pop up' windows.
You can run a "service" (the server) on your board and connect to it
with a client. The client will run on an arbitrary platform: win,lin,mac...
This is what you see when you try to configure a router:
a web server is running on the router, and you connect to it with your browser
(client).
if you want to "view" the X-server running on your board from your pc (and the
apps running on it),
you need a VNC server running on youe board, and a VNC viewer (client) running
on your pc.
I'm confident this can be done with nano-X, but the display-less server may be
a complication;
maybe you'll need some hack to use a portion of ram as "display" and point the
server to it.
I hope someone else can help you more than me on this.
In my opinion, the web way is simpler in your case. But maybe i'm wrong, i
don't know
what you want to display, and if it is simple to render via HTML.
I am probably confusing "server" with "client". I am sorry for that. I
just want to say that my board does not have any sort of graphics
chipset on-board. All what it has is gigabit ethernet.
I must confess I am not sure what is VNC.
http://en.wikipedia.org/wiki/Virtual_Network_Computing
In good old days I used to
build my own PC boxes with graphics cards and run Linux on these. I
still rememer the fun of setting up X-servers and getting all the
resolutions. But it was 15 years ago. I did not encounter VNC back then.
So perhaps I am now misusing the nomenclature.
In any case, I described my goals. Can nano-X help?
Thank you -- Wojtek

maybe i misunderstood your situation.
if i remember right nano-X support some form of VNC server, but...
what's the benefit in having an X server on a display-less device?
Why don't you put a webserver on your board, and write your app as
html pages?

Hi:
This may be a FAQ. I apologise if the answer is already written
somewhere.
Can Nano-X display on remote X-term, much like regular X would?
I have developed an embedded system without any sort of graphics or
keyboard. The board is running uCLinux. It has an ether interface. I
would like to run a graphical app and interact via x-term. Does nano-X
support such display?
If not, what are the alternatives to nano-X? I would rather not bring in
the full X-11 because my board may not have the resources.
Thank you,
Wojtek
