Depuis quelques jours je parcours le forum en espérant trouver un problème similaire avec une solution mais jusqu'ici c'est chou blanc , en précisant aux personnes qui auraient des idées quant à la résolution de ce problème que je débute mais que l'univers ubuntu me parait bien plaisant.
Cordialement
Edit : le problème a été résolu en masquant le pin 20 de la carte (voir lien sur la dernière page) et aucun souci à constater par la suite
