我在 GMKtec 迷你电脑上全新安装了 Ubuntu Server 22.04。无线或蓝牙无法工作，但蓝牙显示正在运行，但找不到任何设备，并且 Wi-Fi 无法配置。我阅读了其他帖子，但找不到有效的答案。以下是有关我的系统的所有信息。我只是缺少 Realtek HW 的驱动程序吗？请帮忙

查看安全启动是否已启用，mokutil --sb因为需要禁用安全启动才能正常工作，然后
sudo apt install git dkms
git clone https://github.com/jeremyb31/bluetooth-5.15.git
sudo dkms add ./bluetooth-5.15
sudo dkms install btusb/4.1重启
