Software Rendering for GNOME Shell
The GNOME Shell experience is now available on all hardware, including those using software rendering. Users still wishing to use GNOME's fallback mode can enable it manually by accessing the System Info control panel applet, selecting Graphics, and setting the Forced Fallback Mode option to ON.
The X server and libraries in Fedora 17 support version 2.2 of the XInput extension, this includes multi-touch support. Applications that choose to will now be able to take advantage of multi-touch support on Fedora.
