我的联想 ideapad 330 上安装了 Ubuntu 18.04。我的耳机已连接，但蓝牙无法打开。
任何帮助都非常感谢。我尝试将内核从 4.15 更新到 4.19，但无法启动。

答案1
要修复 4.15 内核中 USB 设备 0cf3:e500 的这个问题，请在终端中执行
sudo apt install git build-essential dkms
git clone https://github.com/jeremyb31/newbtfix-4.15.git
sudo dkms add ./newbtfix-4.15
sudo dkms install btusb/4.0mokutil --sb-state如果此回复“安全启动已启用”，则需要进入 UEFI/BIOS 设置并禁用“安全启动重启”
