我安装了 ubuntu 14.10 但启动很慢。
我搜索了网络并发现了一些关于检查 dmesg 的研究，我这样做了，发现我的蓝牙存在一些问题并解决了这个问题。
但是正如您在代码中看到的，还有许多其他我无法解决的错误，我需要帮助来解决它们。
日志显示 ACPI ERROR
固件错误
以及 nouveau 的某种错误。

我该如何解决 Nouveau 问题？
答案1
对于图形驱动程序，请安装版本 349.12（撰写本文时的最新版本）
对于 ACPI“错误”，它们只是警告您的 BIOS 不符合 ACPI 标准，因此：
- 将您的 BIOS 升级到最新版本，看看这个问题是否消失。
- 如果 BIOS 升级后问题仍未消失，请联系您的硬件供应商并告知您收到的“错误”，帮助他们解决问题并返回步骤 1... ;-)
- 完毕！ >:)
