Bonjour à tous.
Comme indiqué dans le titre, je n'ai plus du tout accès au bluetooth sur mon laptop.
J'imagine que l'élément déclencheur a été le passage récent au kernel v4.15.3. Je n'ai pas eu de souci immédiat mais après une sortie de veille : plus d'icône bluetooth dans la barre de menu, plus la possibilité de l'allumer en passant par les paramètres systèmes. Rien.
Je suis revenu au v4.10.17 mais ça n'a rien changé. Quelqu'un aurait une idée ?
