![安装 Gnome 桌面后启动性能下降](https://linux22.com/image/1103104/%E5%AE%89%E8%A3%85%20Gnome%20%E6%A1%8C%E9%9D%A2%E5%90%8E%E5%90%AF%E5%8A%A8%E6%80%A7%E8%83%BD%E4%B8%8B%E9%99%8D.png)
我通过一张精简版 CD 安装了 Ubuntu 14.04。它看起来像一个终端窗口,所以我执行了:apt-get install gnome,它下载了很多东西。然后我重新启动并创建了一个帐户。
Ubuntu 启动花了很长时间,我看到一个带有四个点的紫色屏幕,它们亮起然后熄灭,然后它说正在尝试建立网络连接。然后等待最多 60 秒进行网络连接,最后它加载但似乎需要 10 分钟。
我对 Ubuntu 或 Linux 不太了解,也不知道该怎么办。以下是我的dmesg.txt

答案1
我看到您发布的输出中的第一件事是:
IPv6: wlan0: IPv6 duplicate address fe80::5a94:6bff:fe22:3680 detected!
理论上不应该发生这种情况,因为 ipv6 地址使用理论上唯一的 mac 地址作为地址结构的一部分。因此,不知何故,您已成为统计异常的对象,无论是精心设计还是意外。
无论哪种方式,网络接口停滞都会导致启动停滞,直到经过比正常超时更长的时间后才能恢复启动。
