没有网络时登录需要很长时间

我注意到，升级到 14.04 后，当我的 Wifi 连接不佳或从登录屏幕禁用网络时，登录可能需要两分钟以上的时间。

如果我的网络连接良好的话，那么就只需要几秒钟。

我已经禁用任何可能需要网络的启动程序，但即便如此，从登录到桌面也不应该停止等待互联网。

有什么想法吗？

笔记本电脑以太网？您的图形启动动画/记录器 (Plymouth) 正在等待您的硬线网络连接，以便您可以安装任何网络文件系统。要解决您的问题，您可以继续更改 Plymouth 的超时，或者您可以指定您的以太网适配器不由 NetworkManager 配置 - 尝试将“auto eth0 inet dhcp”附加到您的 /etc/network/interfaces 文件中。
