Display Manager question

Tom Dunne

At least I think it is the Display Manager I need to ask about.

I'm coming up with a student project that will involve a Linux server and a few Raspberry Pi's as thin clients.

I want the login banner like this:



displayed from the server onto the Raspberry Pi display. So the Raspberry Pi is logging into the server, not locally to the Raspbian OS. I presume I have to edit a config file on both machines, but I can't seem to figure out what I need to do.

I've tried various permutations of 'thin client' and 'remote XDM' and so on, but I can't seem to articulate for Google what I am trying to do.

Any pointers?

What about VNC? Found this:

Don't forget that X is a reversed (to what is normally expected) client-server.
The system with your screen (the Pi) is the X-Server and the application you call is the client.

And you are correct xdm is the very basic window manager that looks like the image you posted. I haven't seen it in a while!

No, that completely defeats the purpose of what I am trying to do. I don't want to remote control, I want everything to run on the server and display on the thin client through x-windows.

Also, I will most likely have 10-15 clients connecting at one time, so VNC is not suitable for the job.

Ah, it's all coming back to me now. It's literally been 15 years since I looked at this stuff. Just to add, this is what I am trying to do : http://en.wikipedia.org/wiki/X_terminal

Of course, back in my day, we used to call them X-terminals. Now you kids call them thin clients.

Yeah, it's been a while. Though I am not necessarily hung up on xdm, it can be any login screen from any display manager, as long as I can emulate the x-terminal/thin client concept.

I've just stumbled across xdmcp, that rings a bell.....

Bingo. That looks like what I am looking for (as you can see from my previous post about 2 mins after yours).
