Fedora core 7 : install vnc

Bonjour, je viens d'installé vnc sur un linux Fedora Core 7. Je lance le server avec la commande "vncserver" le server demarre bien. Mais lorque je vais voir dans le fichier ~/.vnc/localhost.localdoamin:1.log voila ce que je trouve et je pense que c'est à cause de ca que mon server ne marche pas :
