启用Ubuntu蓝牙驱动可参考以下步骤:
lsusb或lspci命令,查看是否有蓝牙设备被识别。systemctl status bluetooth,若显示“inactive (dead)”或“disabled”,则执行sudo systemctl enable bluetooth和sudo systemctl start bluetooth来启用并启动服务。sudo apt update和sudo apt install bluez安装。若为Broadcom或Realtek适配器,可能需安装sudo apt install firmware-realtek。bluetoothctl找不到设备,可尝试sudo modprobe btusb重新加载蓝牙模块。bluetoothctl输入power on开启蓝牙,scan on搜索设备。
