Voilà je pense avoir été le plus exhaustif possible, si néanmoins des informations supplémentaires sont nécessaires à la résolution de mon probléme, je vous en ferais part dès que possible.

Soyez indulgent avec les non informaticiens comme moi qui découvre et apprécie GNU/Linux au quotidien.

Sincères Salutations.
