这是来自的转发我在 Arch 论坛上的帖子和我的 reddit 帖子。
你好，
我正在运行全新安装的 Arch。我使用 Logitech 的 MX Master 3S 鼠标和 MX Keys 键盘。在我之前安装的 Arch 上，我可以连接到这两个设备，但在全新安装上却无法正常工作。设备出现在可用设备列表中，我尝试连接，但连接失败。我的 Wifi + 蓝牙板是rtl8821ce。
我尝试安装rtl8821ce-dkms-git来自 AUR 但出现以下错误：
ERROR: Missing 6.2.10-arch1-1 kernel headers for module rtl8821ce/1.0.5.r153.ga3e2f7c.
以下是有关我的配置的一些信息：
Arch 版本
$ uname -r
6.2.11-arch1-1
连接失败后 journalctl
$ journalctl -b --no-hostname | grep -i blue

以下所有解决方案均无效：
- 手动构建并安装
rtl8821ce-dkms-git - 构建并升级到最新版本的
linux-firmware软件包 - 禁用蓝牙卡的 USB 自动暂停功能。
- 使用内核提供的
rtw88驱动程序 bluetoothctl trust [device mac]配对前使用- 重启蓝牙服务
- 使用 MX Master 3S 鼠标附带的全新 Logitech“Bolt”加密狗并与以下设备配对
solaar：不断断开连接。 - 使用以下方式进行完整系统升级
pacman -Syu - 检查蓝牙设备是否被软阻止或硬阻止
sudo rfkill list
答案1
编辑：使用linux-ltskernel 而不是linuxkernel 解决了！我现在在6.1.25-1-lts。
