I was sent this demo, on YouTube, of Xgl in action. Xgl is a graphics/windowing subsystem, used by Linux. Or rather, according to Wikipedia, Xgl is “an X server architecture designed to take advantage of modern graphics cards via their OpenGL drivers, layered on top of OpenGL via glitz. It supports hardware acceleration of all X, OpenGL and XVideo applications and graphical effects by a compositing window manager such as Compiz.”
It’s running on some flavour of Linux—I don’t know if it’s Ubuntu, or Kubuntu, or something else entirely, because I don’t know enough about the different flavours of Linux. Anyway, here’s the demo. Enjoy!
I’ve seen other Xgl demos—all on YouTube—but this is probably the best quality one.
