Bonjour à tous,
Je viens d'installer ubuntu, et après avoir (miracle !) réussi à faire fonctionner la fonctionnalité Wi-Fi, c'est à présent le Bluetooth qui me fait des caprices.
J'ai beau toucher le bouton 'On/Off' en haut à droite dans la section Bluetooth des paramètres, j'ai toujours le message « Bluetooth désactivé. Activez pour connecter des périphériques et recevoir des transferts de fichiers ».
De plus, dans le menu déroulant qui apparaît quand je clique en haut à droite, il est écrit « Bluetooth : Éteint », mais quand je clique dessus, il me propose « Éteindre » et « Accéder aux paramètres » (et non « Allumer » et « Accéder aux paramètres ».
Que faire ?
Merci d'avance !
sudo rfkill list
