Nothing happened? After making of fg-ehci-headtracker, type ./headtracker & and type the fgfs cmd to go into the cockpit: fgfs --geometry=1024x768 --timeofday=noon --aircraft=dhc2F --generic=socket,in,25,localhost,5550,udp,headtracker --generic=socket,out,10,localhost,5551,udp,headtracker --prop:browser=/sim/headtracker ./headtracker.xml I can see myself in the trackwindow, and in the fgfs windows, I saw a line of hint that I can use "=" to reset track, and I saw a little window, to set values of the axises, I leave them all zero and close this little window, now I try to begin fly, but, when I type "=" button of the keyboard, nothing happened, I can see my head swing in the track window, but in the fgfs window, still, silent, is it right? Did I miss any operations or confiurations before going into cockpit?
