联想 G780 上的蓝牙

它就是不工作。在蓝牙设置中，它显示蓝牙已禁用，切换它没有任何作用。

是的，我安装了 105b:e065 固件，蓝牙正在初始化，但仍然无法工作。另外：

~$ hcitool dev

在我能够完成 dkms 之前，以下内容将一直有效，直到内核更新

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

已经完成了 dkms

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

重启
