以太网设备在 arch linux 上不受管理

我在 arch linux 上使用以太网连接到互联网时遇到问题。我使用 NetworkManager，它告诉我Device not managed有关以太网的信息。

  • 这是我的内容NetworkManager.conf

    # Configuration file for NetworkManager.
# See "man 5 NetworkManager.conf" for details.
[ifupdown]
managed=true

  • 这是服务的状态

该/etc/network/interfaces文件在我的机器上不存在，但是我发现需要此文件来解决此问题（至少在 ubuntu 上）。

我对网络方面的东西不太熟悉，所以我很乐意提供有关如何解决此问题的任何建议。

编辑：我发现，当我在没有插入电源线的情况下启动笔记本电脑时，不会发生这种情况。但是，如果我这样做，我将无法再打开我的外部显卡（optimus-laptop），而且我真的不这样做查看以太网设备、显卡、电源线之间的连接

检查/etc/netctl/eth0里面是否有文件或类似文件/etc/netctl。如果您需要 NetworkManager 处理此 NIC，请删除该文件。另外，sudo systemctl disable dhcpcd要禁用外部 DHCP（它将由 NetworkManager 处理），请重新启动系统，然后 NIC 将由 NetworkManager 管理。否则，您可以使用 dchp 或静态 IPeth0通过编辑进行设置。/etc/netctl/eth0
