Charles,
Both the Linux and Mac applications that we are distributing are 'graphics capable'. However most Linux & Mac users don't see the graphics because the BOINC project has not yet done a public distribution of the BOINC manager, which is the tool that sends the 'display graphics' and 'undisplay graphics' commands to the application. We have been using and testing this tool on Linux and Mac for several months. Hopefully the BOINC project will start public distribution of this tool soon. Then Linux and Mac users can watch the graphics too!
Cheers,
Bruce

You know it never occured to me that one could just telnet in -- it's a good idea. Could you please post a brief transcript of your telnet session? It sounds like a good debugging technique for some purposes.

Thanks! BTW, this also works

Thanks!
BTW, this also works on the Mac and even on Windows.

Why? The telnet client should work without having a server running on the machine. In this case the boinc client should be the server that is contacted by telnet. Is there a telnet client distributed with any Linux distri that doesn't work without a telnet server?

The keyboard commands are working in a test version of the code but are not yet in the production version of the code.

The graphics shouldn't be CPU
)
The graphics shouldn't be CPU intensive, as they are mainly done by the graphics card, not the CPU.
You can assign priority levels to processes so that some are executed when there's nothing else to do. These processes are "nice" in the sense that they step back when there is more urgent work to do. %nice is the amount of time the CPU spends with such processes.

You entered what? (everything that looks like HTML tokens is filtered out)

RE: Is there any chance

It is working on Macs (both PowerPC and Intel).
It looks like you're using the standard BOINC client. If it's correctly installed (don't know whant you can do wron there...), open the BOINC Manager, click the "Tasks" tab, select the task that is currently "running" and click the "show graphics" button (this will send the right message to the client without you typing on the command line). A window should pop up showing the starsphere.
To run it as a screensaver, select BOINCSaver in the screensaver system preferences. Define a "hot corner" to see the effect immidiately, the "test" mode doesn't work with the BOINC saver.
