Ubuntu 14.10 启动非常慢

Ubuntu 14.10 启动非常慢

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:

  1. 将您的 BIOS 升级到最新版本,看看这个问题是否消失。
  2. 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... ;-)
  3. 完毕! >:)
