必须手动启用蓝牙 - Ubuntu 22.04 Lenovo Legion

在 上升级到最新 BIOS（J2CN40WW）后Legion 5 Pro 16IAH7H Laptop (Lenovo) - Type 82RF，Ubuntu 22.04 启动后未启用蓝牙。

我需要手动打开设置并启用蓝牙，然后它才能开始工作。对于较旧的 BIOS（v32 左右），这不是问题。

知道可能是什么问题吗？

开机后蓝牙还未工作时：

$ rfkill list 1
1: ideapad_bluetooth: Bluetooth
    Soft blocked: yes
    Hard blocked: no

运行sudo rfkill unblock bluetooth启用蓝牙。BIOS 没有蓝牙配置。

答案1

rfkill list 1

两行都应该显示“否”：

1: phy0: Wireless LAN
  Soft blocked: no
  Hard blocked: no

如果软阻塞是肯定的，则原因与软件有关。如果硬阻塞是肯定的，则原因与硬件有关。请使用您得到的命令和结果编辑问题。

你需要一个 ...

sudo rfkill unblock bluetooth

如果这不能解除软锁请执行以下操作......

sudo rfkill unblock all

并再次检查。

如果你需要在重启后重新应用此设置，则你的 BIOS 可能已禁用蓝牙，因此请查看：当你更新 BIOS 时，它可能已被设置为禁用（如恢复出厂设置）。你可能还需要

sudo systemctl restart bluetooth

之后rfkill。

这两个命令都应该需要一次，并且在重新启动时保持您离开时的状态。如果不是，请发表评论。

如果这些有效，请测试其中一个并将其用作永久解决方案（只需要其中一个）：

  • 添加rfkill.default_state=1到 GRUB 启动选项（启动时首先执行 ，如果可行，vi /etc/default/grub请执行 ，找到GRUB_CMDLINE_LINUX_DEFAULT，并在末尾添加rfkill.default_state=1（带空格） ，保存并执行sudo update-grub）。

    （您可以通过删除所添加的字符串来恢复此操作）

  • 黑名单（pilot6 的评论）将是

    sudo nano /etc/modprobe.d/blacklist.conf

    并添加

    blacklist ideapad_laptop

    （您可以通过删除所添加的行来恢复此操作）

这老虫子似乎与此相关（尽管是关于解锁 wifi 而不仅仅是 BT）
