You're looking for the Wayland project. Excellent implementation. They reuse lots of ancillary X11 code too, like the input code from X.org, which has the virtue of working with a billion weird language/input/hardware combinations. You can run X applications on top of it, transparently. They perform just as well. GTK+ and Qt have been ported to it, Gnome and KDE are working hard at getting full ports over. Canonical, of Ubuntu fame, has recently started working on a competitor, following the same strategy, called Mir. They've ported Qt to it, but are generally lagging. Wayland has the advantage of being crewed almost entirely by old X.org hands, who know a lot about what they're doing.
