    Question Bluetooth is disabled

    Hello All,
    My Bluetooth isn't working. The Gnome Bluetooth app says that Bluetooth is disabled, and will not (or can not) turn it on. I checked the bios for my Dell Inspiron 6400 laptop and have it set that bluetooth is enabled. I also have it set so that the function-key+F2 toggles it on and off along with my wireless card, however the wireless icon is on (and works fine), but the Bluetooth one is not (and does not work).
    My question is, how do I turn it on?
    Thanks,
    Erik.

    Re: Bluetooth is disabled

    Hi,
    First of all, you have had working Bluetooth in the past? If so, what broke it? If not, are you sure the hardware is present?
    Open a terminal (Start/Accessories/Terminal), and type in the following command. Post back the output; it may help.
    Code:
    hciconfig -a

    Thanks for your reply coffeeaddict22!
    I don't know if Bluetooth has worked in the past or not with this laptop as I have never tried it. I can say though, that there is a Bluetooth symbol on the laptop, beside the wireless symbol, but it is not lit.
    I entered
    hciconfig -a
    in a terminal, and got no response, meaning that I got no error messages.
    Thanks,
    Erik.

    Hmmm. There's a particularly unpleasant Windows stunt you may be dealing with. If the Bluetooth has been turned off in Windows, you may need to boot into windows to turn it on. Have a look here, and (more specifically ) here.

    Uh oh. That would be a huge bummer. I haven't had Windows on this computer for a long time. Crazy to think that a hardware setting from within Windows long since removed can't be changed by Linux. I haven't had a chance yet to go through it all, as it is late here. However I will have some time this weekend. I'll post back my results.
    Thanks for the info coffeeaddict22!
    Best,
    Erik.

    Have to agree it's not particularly nice. The HP laptop that had the problem (I think I gave you the link) did get out of it by selecting Reset to Defaults in BIOS settings, so you might get lucky (and if you're not a hardware hacker you won't lose any important settings).

    Re: Bluetooth is disabled

    I wonder if it is possible to shrink my linux partition and install Vista (I think I have my old install disk somewhere) without gimbling my linux boot partition. Make the necessary change and then remove Vista and restore my linux partition?
    This I will try to research.

    This thread has some links to really good explanations on how to make space for a Vista installation, then how to repair the master boot record afterwards:
    All I need to do now is find my old Vista install CD (where ever that is). I haven't used it in a while.

    Re: Bluetooth is disabled

    I have a company Dell Inspiron 6400 with its original WinXP Pro and it has the Bluetooth LED on it. But that is an option that has never shown up in WinXP, so not on that laptop and probably not on your laptop. Does sudo lspci -v show any Bluetooth device?

    So I am not sure how you would tell "if" you have Bluetooth option. If you have it, maybe it requires a proprietary driver like wireless does. See if System, Administration, Hardware Drivers shows anything related to Bluetooth.

    I did get Broadcom wireless working from a 9.10 live/install iso on bootable USB. Not sure how that works on a regular install, but even after I activated the Broadcom STA driver, it did not load automatically from live/install version. I had to sudo modprobe wl for it to work (although, that did not light wireless LED). Rather than tampering with init scripts, I just added this to ubuntu user's ~/.profile to automate that if the live USB was running on the Dell:

    Code:
    # load Broadcom wireless module if Dell laptop
    if lspci | grep -q BCM4311; then
            lsmod | grep -qw wl || sudo modprobe wl
    fi

    As far as I can see, there is no specific reference to any type of Bluetooth service other than what is contained in the Network Controller: Broadcom Corporation BCM4311 802.11b/g WLAN. Additionally, there is no other driver for Bluetooth outside of the Broadcom B43 wireless driver.

    As well I found this thread: http://ubuntuforums.org/showthread.p...ight=Bluetooth, and entered lsmod which didn't bring up any references to Bluetooth. So I'm not really sure right now whether Bluetooth can work or not with my computer.

    Thank you,
    Erik.
