I don't know what your simple program does, but it sounds like it could be a Sugar bug. You should file a ticket at dev.sugarlabs.org. If it is not related to Sugar, we'll try to pass the report along to the proper place. http://dev.sugarlabs.org/ticket/465 It does sound like NM. Look at

Hi! I would like to ask these questions from OLPC staff: Does this also mean that people who already own XOs will find that new software is going to require a computer more powerful than they currently have? I thought that that was something that was going to be specifically avoided.

I think most of those effects can be just as easily be done by the 2D engine (like what the Geode has). Of course it would need a LOT of coding, like killing the stupid X driver model with the X server process, using a compositing windows manager, rewriting GTK+ to use some form of retained

Actually, GNOME 3.0 is moving into that direction (requiring OpenGL): http://lwn.net/Articles/327845/ Hehe, seems like that I have just invented Clutter... :) More seriously, it seems that Sugar just runs ahead of Gnome and reinvents almost everything which will be created by Gnome people

A small amount of testing would be very good, yes. We don't expect any changes to be visible outside of the firmware and battery charging (behavior should be better in the presence of batteries with extremely low charge), but we should double-check that everything looks normal. Seems a

I have just tested it on my XO and the Geode DOES NOT support the ffreep instruction. It could explain the halting shutdown when it stalls with a signal 15 (which happens to be SIGILL) and only continuing it when I switch to the other console (as I reported in [1]). So fixing it and creating a

You are mistaken. The Geode LX has a two scaler units, and neither can feed back to the main CPU. One of them is in the Geode Display Controller (not the DCON), and simply scales the entire screen to the output. The other is in the Video Controller, and can be used only for overlay
