根据Fedora 的邮件列表信息，在Fedora 17中，Gnome shell将可以在没有3D加速的情况下工作。
As of tomorrow’s rawhide [1], gnome-session will no longer treat llvmpipe as an unsupported driver. This means gnome-shell will run even on hardware without a native 3D driver, including virt guests.
这意味着所有人将可以用上Gnome shell,GNOME Fallback将不再需要。这引起了另一个问题：以后是否需要提供GNOME Fallback？
