Comment installer Flightgear-Osgearth pour Linux

Je suis parvenu à lancer un vol avec le Cessna en changeant d'aéroport, mais le cessna est impilotable, je vous met la vidéo pour vous faire une idée.

Puis là, je n'ai plus accès aux menus une fois FG lancé, retour de la console:

De même quand je modifie certaines options de osgearth, plantage. Mais je tire mon chapeau à f-fjth pour son script. Un grand merci à lann et f-toro pour leur persévérance.
