Habe gerade Lenovo B5400 gekauft und 14.04. installiert. Alles läuft ohne Probleme bis auf Bluetooth. Was mich stutzig macht ist, dass im Terminal beim Name Bluetooth der Wortanfang Blue in roter Farbe ausgegeben wird (was hier nicht zu sehen ist). Deutet das schon auf ein Treiberproblem hin?
Network controller: Broadcom Corporation BCM43142 802.11b/g/n (rev 01)
Hier die Ausgabe für dmesg | grep i blue:

Hier die Ausgabe für hciconfig --all:

Und hier für lspci:

Allerdings irritiert mich die Ausgabe rfkill list:
erhard@erhard-B5400:~$ rfkill list 0: tpacpi_bluetooth_sw: Bluetooth Soft blocked: no Hard blocked: no 1: hci0: Bluetooth Soft blocked: no Hard blocked: no 2: phy0: Wireless LAN Soft blocked: no Hard blocked: no 3: brcmwl-0: Wireless LAN Soft blocked: no Hard blocked: no
Was kann/sollte man machen?
