Syllable, AtheOS

The Syllable project is pleased to announce that the reports of its death have been greatly exaggerated, and that the new version 0.4 of Syllable Server has been released. This release focuses on maturing existing functionality, improving security, ongoing system restructuring, and making the system a suitable base for third-party package managers. Although the project admits it hasn't brought its unicorn factory online yet, extensive work was done on the nitty-gritty, so the full change log is quite long.

" [q]First, NVidia's driver is a bad example and you know it: it's proprietary, fortunately there are lots of other open source drivers bundled in Linux that you can modify as you wish..

And that either can't do hardware acceleration on 5-years old hardware or do it 4 times slower than the proprietary driver. Yeah, I've heard about those...

And? Syllable desktop/Haiku/anything don't provide anything better for NVidia HW..
And they won't anytime soon as they're busy re-inventing everything from scratch. [/q]

In the case of Syllable, by "everything" you mean that less than one percent of our own code that is in Syllable Desktop?

" Question : if I run several CPU-hogging apps (something in the vein of while(1);) in a terminal, does a DirectFB desktop remain responsive, unlike something based on X ?

1) I don't know..
2) Does this really happen if the X-server is reniced to a higher priority?

If it doesn't, why don't all X11 systems do this? And if you have to do the renicing yourself, does Aunt Tilly know that?

I do know that X11 is notoriously not designed to make the best use of the hardware and not designed for best responsiveness. The worst culprits are the heavy serialisation it does even on multi-CPU machines and the round-trips between apps, server and window manager.
