buongiorno Ho un laptop lenovo r61 e sono passato da windows 7 a ubuntu 14.04.Il bluetooth riesce a trovare i vari devices attorno a lui ma non riesce a comunicare con loro. Dal momento che il bluetooth scopre un devices e fa paired, compare un piccolo lucchetto sull'icona del bluetooth e non succede nulla.Allora disconnetto il bluetooth dal device che perde il collegamento ed anche il lucchetto scompare.Puo' essere un problema di drivers? Ho surfato pomeriggi interi ma non sono riuscito ad inquadrare il problema. C'e' qualche volontario che aiuta questa anima in pena informatica? Ringrazio in anticipo qualsiasi risposta che possa dare speranza alla suddetta anima in pena. |

un piccolo aggiornamento: ho provato sul mio lenovo r61 un'altro sistema operativo, Kali Linux ed il bluetooth funziona perfettamente. mi chiedo se e' un problema di kernel? |

vorrei riuscire a mettere meglio gli out-put, cosi vien poca voglia di leggerli...mi dispiace. Se qualcuno m'insegna come fare e' benvenuto
Non usare le risposte per postare gli output ;-) Te li ho convertiti in commenti. Se non vuoi mettere righe e righe nei commenti, puoi usare ad esempio pastebin.com, dove associ un link condivisibile a un file di testo.
ok grazie per il consiglio
