Ubuntu Karmic has option for turning off bluetooth

I have Ubuntu Karmic in netbook (Lenovo Ideapad S10). After installing updates (update manager called it partial upgrade) I see a new option to turn off or turn on bluetooth from the bluetooth icon in top panel

Below screenshot shows bluetooth turn off option




Below screenshot shows bluetooth turn on option






I have Ubuntu Karmic in my netbook installed along with Arch Linux. I have shared my home directory between Arch Linux and Ubuntu Karmic so used a different user name (a yaksha my favorite character in Mahabharat who questions King Yudhistira) to avoid conflict!

    Hi

    I just installed the bluetooth thumbnail sized card in my lenovo s10 netbook, and Karmic still says "no bluetooth adapters present." Maybe it's turned off, in the OS or bios. Any ideas? you can email me at dreamtrove [at] gmail [dot com] if you have the answer to this.

    Thanks a lot

    Jon

    Ubuntu may not have driver for the model loaded by default as it may not know what driver needs to be loaded for it, since it is an external card I guess. If you know the model and search and find out what linux module to be used, you can load it in Ubuntu yourself using sudo modprobe <modulename>

    where you should replace the <modulename> with the correct module name without any angular brackets

    for e.g for belkin usb adapter for networking, if ubuntu does not load the module, I can load like this

    sudo modprobe zd1211rw

    Hi,

    I have a similar problem with a Dell bluetooth dongle not being recognised by Ubuntu Karmic - had no issues with 9.04.

    Can you please tell me how to find out the module name for a Dell bluetooth dongle so that I can try the modprobe command?

    After reading that thread, someone tells that the following command makes bluetooth work

    sudo hciconfig hci0 up

    Thanks a lot for the link - almost the identical problem however, none of the suggestions have worked so far.

    The problem was the bluetooth dongle was in HID Proxy mode and was not switching to HIC. The solution is to

    1. Remove dongle.
    2. Press red dot.
    3. Insert dongle while the red dot is pressed and hold it down for a few seconds.

    Thanks to niteshifter at http://ubuntu-ky.ubuntuforums.org/showthread.php?p=8298037

    Hope this will help someone else as well.
