I am using ubuntu latest lts (14.04.3). My laptop does have Bluetooth and I can use it in windows 8. However in Ubuntu it seems that the OS doesn't recognize the hardware.It is not listed on the top bar, under the Hardware>Bluetooth.

Your wireless/bluetooth adapter is natively supported by kernel 4.3.

The backport you have installed to get your wireless adapter working probably has broken the bluetooth.

Install the kernel this way:

mkdir ~/linux-4.3
cd ~/linux-4.3
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.3-wily/linux-headers-4.3.0-040300-generic_4.3.0-040300.201511020949_amd64.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.3-wily/linux-image-4.3.0-040300-generic_4.3.0-040300.201511020949_amd64.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.3-wily/linux-headers-4.3.0-040300_4.3.0-040300.201511020949_all.deb
sudo dpkg -i *.deb

and reboot.

You will also need an updated firmware. It has been uploaded to proposed already. Install the deb file this way:

wget https://launchpad.net/ubuntu/+archive/primary/+files/linux-firmware_1.127.18_all.deb
sudo dpkg -i linux-firmware_1.127.18_all.deb

This package will get into main repositories in a week or too.
