Spacenavd, is a free software replacement user-space driver (daemon), for 3Dconnexion's six-degree-of-freedom input devices. It is compatible with the original 3dxsrv proprietary daemon provided by 3Dconnexion, and works perfectly with any program that was written for the 3Dconnexion driver. It also offers another method of accessing the device via a new non-X11-dependent protocol.
