Confirmed (as root):

You must set the DISPLAY environment variable for X

When I connected as 'user' I get:

Warning: No xauth data; using fake authentication data for X11 forwarding.

...then it just sits there.

*edit: This wouldn't have anything to do with needing to switch ttys would it? Seems like a window's jusrt not popping up.

The xauth message is just that - a warning message. I don't know yet why you would get that.
I've also placed xeyes on the application host. Can you display that? If no then the problem is not the POS code and we can take the focus away from it. If yes, then it's our problem here and we can narrow our focus to it. It's been a good day - we're learning.

Beautiful!!! xeyes occupied the full window and would look wherever I touched the stylus to the screen. Dragging also mimicked the effect they normally exhibit with a mouse. So your host was doing all the background processing and the 770 was just responsible for the rendering? Good lord, I finally 'get' the ramifications of everything you've been saying. I think we'rein for some interesting times.

xeyes worked for me too! now, if we can try out the pos...

Eugene, just to let you know, when running xeyes, tapping the stylus on any part of the screen gives a second of delay before the eyes move. Dragging the stylus however gives around a quarter of a second delay. I'm not sure if this helps.

I choose to regard the 770 as a wireless handheld x terminal - a touchscreen display that is network-driven. For me, the 770's 'desktop' is not so much a view of what is contained within the 770 and available to the user but also a view of what is available anywhere on the wide area network.

I talked yesterday with someone who recently sat in his home with his wife & kids while he was putting four new items on the menu in the 80 restaurants operated by the company he works for, all across Canada, while the people in the restaurants were using their systems. He did not use a computer, by the way, he only used a touchscreen display that was connected to the network! He makes use of openVPN (along with my pos) to continuously connect to all of those locations, bypassing the traffic of the world wide web. He manages all the IT work for his company all by himself, part time. Nobody at any restaurant organization has ever even dreamed of creating the kind of efficiency and control he has achieved. Even the people running the organization he works for don't really comprehend what has been done. I've visited restaurant companies that have a staff of 12, 15 or more as they attempt something similar, and fail. I know of a restaurant organization not too much bigger that has spent over $20 million attempting this and has failed. I could tell you stories.

In the 22 years since X first was created, nobody has ever built a handheld wireless touchscreen device before that ran X. Now that Nokia's done it the genie is out of the bottle. Not even Nokia understands what they've made possible, yet. More apps tomorrow and, hopefully, pos.

Meanwhile, anyone who has ever added an application to the KDE or Gnome panels, or to a windows/apple desktop would now be thinking how to add an icon to the 770's display that can contain the ssh command to open a display to any remote X client application. As soon as someone does that then the 770 has a network-driven GUI, not just a device GUI, and the number of icons you can have in the GUI, the variety of client apps & storage that you can access with your 770 GUI is virtually unlimited - it's bigger than the world wide web because it includes the entire Internet, not just the www.

One more thing - any app on that box you open a window to is running on FreeBSD 6.0. The eyes would look exactly the same if the box were running any Linux distro, or any other OS that X abstracts, so you wouldn't know or have to care because X means that not only is the remote hardware irrelevant, but so is the remote OS. And if the box got too busy instead of building a server farm we would just migrate the client application to a cluster (or grid) and move the storage to the network.

I successfully ran xeyes at about 14:35 GMT and am trying the openterm now... I got the X11 forwarding warning both times. I'm just leaving it, assuming it's downloading a ton of stuff... Memory usage is low (two bars).

Remote, has anyone gotten the POS demo to work on a 770 yet?

ah, good old xeyes finally works ;

but I haven't got openterm to run yet. I enter the password, get the warning (no Xauth data; using fake...), which also appeared before xeyes came up, the cursor rests in the next line, and that's it.

Out of curiosity, what happens if an app tries to display data bigger than the available screen size? For example, if the POS demo was 1024x768, would scroll bars appear?

XEyes filled up all of the available real estate on the screen...
