我刚刚在 ACER SWIFT 314-44 上安装了 UBUNTU 22.04LTS，与预装的 Windows11 进行了双启动。
安装工作正常，在安装过程中允许并生效了完整的更新和升级。
重新启动后，系统会自动提供、接受和安装新的更新。然后再次重新启动。通过终端，我检查到没有其他可用的更新。
之后没有安装任何其他东西，没有更改任何参数，因此这是一个干净的开始。双启动工作正常。
在 windows11 上，Wifi 和蓝牙均运行正常（启动和停止）。
在 Ubuntu 22.04.3LTS 上，无法启动蓝牙：切换按钮可以移动，但它保持灰色，工具栏中的 wifi 符号旁边没有出现蓝牙符号（既不是灰色也不是白色）。我读过另一个报告类似问题的帖子，并提供了解决方案Jeremy31，但我无法看出这个问题的根源（或根源！）是否相同。
我所理解的是，这个问题已经为具有以前内核（5.19 通用）的机器解决了。此处的安装使用 6.2.0-33 通用内核运行。
以下是有关终端的一些疑问和解答，希望能够帮助找到并解决问题。

感谢您的任何帮助，以及任何必要的进一步终端查询。
答案1
在终端做
sudo apt install git dkms
git clone https://github.com/jeremyb31/bluetooth-6.2.git
sudo dkms add ./bluetooth-6.2
sudo dkms install btusb/4.1重启
我发现你遇到了问题，所以我做了一些改变，
sudo dkms remove btusb/4.1 --all
sudo dkms uninstall btusb/4.1
sudo rm -r /usr/src/btusb-4.1
cd bluetooth-6.2
git pull
sudo dkms add .
sudo dkms install btusb/4.1重启
