Comment 276 for bug 1189721

New Deb-File look here: https://launchpad.net/~blaze/+archive/ubuntu/rtbth-dkms

Use in terminal

sudo add-apt-repository ppa:blaze/rtbth-dkms sudo apt-get update

and look in synaptic for package rtbth-dkms and install it

or load and install it here https://launchpad.net/~blaze/+archive/ubuntu/rtbth-dkms/+packages

On the first link there is the source link to GitHub https://github.com/loimu/rtbth-dkms

On README.md you can read:

# Init sudo modprobe rtbth
sudo rfkill unblock bluetooth
hcitool dev # check

i typed it in terminal and everything works.
