Thanks, yes that ended up as closed as a duplicate of:


Which is reported as fixed (though not something I have tested myself).

If reports filtering through that Uyaguay have indeed already purchased 30,000 (!!) of these for use by teachers then we need to try and get tickets open for all the major cases. Hopefully we will also see some support from the Uy deployment as when saving money thru buying cheaper but different spec hardware, putting some efforts in bringing the needed software up to the deployments requirements must be expected.

Thanks, I think I also caught a photo of it from the recent EduJam flickr stream, nice to see you were well ahead of the storm front ;-)

I'm happy to tweak activities I directly maintain if needed, and provide some design suggestions for others if needed (as long as we don't degrade the experience for the majority). But if the 30k Uy purchase of these machines is an accurate report, we should try to help where we can (understanding that the majority of us are volunteers putting what free time we have into the effort).

When Sugar Labs was spun off from OLPC to work on Sugar, there was much effort from SL to make Sugar more hardware agnostic and work on more traditional laptops, part of this meant that 1024x768 was much more commonly being used and tested by developers; and the default when running Sugar in a window under Gnome was 800x600, which has been generally treated as the worst case scenario. So it's that 480 vertical pixels count, a reduction of 120 from our assumed worst case, that's catching some of us out ;-)
