Ubuntu: Bluetooth on Lenovo G780



Question:

It's just not working. In bluetooth settings it says that bluetooth is disabled and switching it does nothing.

~$ rfkill list  0: ideapad_wlan: Wireless LAN      Soft blocked: no      Hard blocked: no  1: ideapad_bluetooth: Bluetooth      Soft blocked: no      Hard blocked: no  2: phy0: Wireless LAN      Soft blocked: no      Hard blocked: no  3: brcmwl-0: Wireless LAN      Soft blocked: no      Hard blocked: no    ~$ lsusb      Bus 004 Device 003: ID 5986:0295 Acer, Inc   Bus 004 Device 002: ID 8087:0024 Intel Corp.

Yes, I installed firmware for 105b:e065 and bluetooth is initializing now but still not working. Also:

~$ hcitool dev  Devices:  

It's blank and I can do nothing with hci.


Solution:1

Until I can get a dkms done for this, the following will work until a kernel update

sudo apt-get install build-essential linux-headers-$(uname -r)  wget https://www.dropbox.com/s/kj6w4qkantc8sul/btusb-vivid.tar.gz  tar -zxvf btusb-vivid.tar.gz  cd btusb-2.0  make -C /lib/modules/$(uname -r)/build M=$PWD modules  sudo cp btusb.ko /lib/modules/$(uname -r)/kernel/drivers/bluetooth/  sudo modprobe -r btusb  sudo modprobe btusb  

Got a dkms one done

wget https://www.dropbox.com/s/texcobck1yjvhzc/btusb-dkms_2.0_all.deb  dpkg -i btusb-dkms_2.0_all.deb  

Reboot
