    Default Bluetooth doesn't turn on

    Hi all! This is the problem: when i try to turn on bluetooth from the tray icon or system settings, it seems to work, but nothing happen... I can't scan for devices, and in the tray icon is written "Disabled" (but turned on). What can i do? Thanks!

    What is the result of (run as root in a console)
    Code:
    # rfkill
    On some laptops the bluetooth adapter can be toggled on/off by using a special key combination (e.g. on my laptop i have to hold "Fn" while pressing "F11").

    Thanks for the replies! Early today i solved with "sudo rfkill unblock all" because i saw that it was blocking bluetoot. Now the rfkill command say that all is unblocked, but i can't enable bluetooht anyway, i think there is something more...
