蓝牙必须手动启用-Ubuntu22.04联想军团

Question

在Legion 5 Pro 16IAH7H Laptop (Lenovo) - Type 82RF上升级到最新的BIOS (D1)之后，在Ubuntu22.04上启动之后，蓝牙就不启用了。

我需要手动打开设置并启用蓝牙，这时它就开始工作了。这不是旧的BIOS (v32之类的)的问题。

有什么不对的吗？

当蓝牙无法工作时，启动后：

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

运行sudo rfkill unblock bluetooth支持蓝牙。BIOS没有蓝牙配置。

Answer 1

rfkill list 1

应在两行中显示“否”：

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

如果软阻塞是是的，这是一个软件相关的原因。如果硬阻塞是是的，这是一个与硬件相关的原因。请用命令和结果编辑问题。

你需要一个..。

sudo rfkill unblock bluetooth

如果那不解除软锁的障碍做一个..。

sudo rfkill unblock all

再检查一遍。

如果您需要在重新启动后重新应用此功能，那么您的BIOS可能会禁用蓝牙，所以请查看那里:当您更新BIOS时，它可能已被设置为禁用(如工厂重置)。你可能还需要一个

sudo systemctl restart bluetooth

在rfkill之后。

这两个命令都应该需要一次，在重新启动时，请保持将其保存在其中的状态。如果没有，请留下评论。

如果这些工作，请测试其中之一，并使用它作为一个永久的解决方案(只需要两个中的一个)：

• 将rfkill.default_state=1添加到GRUB引导选项(第一次在启动过程中，如果这样做可以执行vi /etc/default/grub，则查找GRUB_CMDLINE_LINUX_DEFAULT，并在最后添加rfkill.default_state=1 (有空格)保存和执行sudo update-grub)。(您可以通过删除添加的字符串来恢复此操作)
• 黑名单(pilot6 6‘s注释)将是sudo /etc/modprobe.d/blacklist.conf，并添加黑名单ideapad_laptop (删除添加的行来恢复此功能)。

这个老虫似乎与此相关(尽管是关于解锁wifi而不仅仅是BT)。
