Ubuntu 13.10、14.04、14.10 在启动时挂起

我不会复制任何线程，但这里的内容相当晦涩。我不是一个聪明的 linux 用户，即使我使用它已经很多年了，但在用户级别，而不是专家级别。

我使用的最后一个没有（重要）问题的发行版是 13.10。

今年圣诞节前几天，我决定升级到 14.10，首先按照正常的升级程序升级到 14.04，这时我的 PC 开始在启动时出现异常。

主要行为是：启动 -> 登录屏幕，整个过程冻结。无法使用键盘、鼠标或触控板。或者（替代行为）成功登录，然后新登录页面（我尝试输入错误的密码并且登录行为正确，说密码不正确）

我能够进行完整备份，然后我决定尝试从 CD 从头开始​​安装 Ubuntu 14.04（这并不容易，因为安装顺序挂起的时间越来越长）现在我有一个 14.04 只在恢复模式下工作.

我附上了一个系统日志文件，其中包含 3 次启动的历史记录，每一次都有不同的警告/错误，希望这足以了解问题出在哪里。我可以根据需要添加信息。
