我的 Ubuntu 现在有一个奇怪的问题。
我的登录速度几个月来都不稳定,有时它会在几周内改变。我的意思是,例如,在 2 周内,启动时间真的很快,但在那之后,启动时间会明显变慢。
通常,在 ubuntu 登录声音播放后,我的桌面已经完成加载,但有时,ubuntu 登录声音已经播放完毕,我仍处于登录的这个阶段 --> image,就像那样。
这有什么原因吗?有时它会在更新后变慢(我认为这很正常?)在重新启动几次后,它变得很快,然后又随机变慢。
编辑:
正如 CYREX 所建议的,这是我从 dmesg 中发现的。请注意,我不太清楚这些数字代表什么,我认为这是某种时间。以下是其中有很大差距的那些,包括一个可怕的,可怕的:

更多关于我的设置:
笔记本电脑设置为双启动 Windows 7 和 Ubuntu。两者都在一个单独的分区中。但是,它们共享一个公共的单独分区,我将所有文件 (/media/Storage -> NTFS) 放在其中。我还在那个共享的 NTFS 分区中创建了 Ubuntu 交换。在我看来那里有什么问题..
我将从引导图开始。它在 apt 树中可用。就提高启动速度而言,ureadahead(我认为在当前的 Ubuntu 中默认安装)可能是最有效的,同时消除了不必要的守护进程等(chkconfig 或 sysv-rc-conf)
