我同时启动了 Ubuntu 16.04 LTS 和 Windows 10。16.04 的安装似乎非常顺利，我已经按照自己喜欢的方式设置好了一切，但我遇到了几个非常烦人的奇怪错误。基本上，大多数时候我尝试登录时，它要么在我开始输入之前就冻结在登录屏幕上，要么在我输入密码并按回车键后，它只会显示桌面背景和 Ubuntu 16.04 LTS 水印。我可以移动鼠标指针，但仅此而已！我必须进行硬关机，然后重新启动。然后有时它会工作，但通常不会。在后续启动时将其从睡眠状态唤醒，它会在某个时候冻结。这一切都是在全新安装的情况下进行的，运行时没有任何问题。我该如何解决这个问题？
编辑：我无法从 DVD 启动，只会出现黑屏。我做了一些研究，尝试了一些方法，但似乎无法解决问题。我目前拥有的文件可能有用吗？
编辑 #2：请耐心听我说，我不知道这有多大用处……这是昨晚登录时冻结时发生的情况，如 kern.log 中所述。我不知道这意味着什么，但我希望有人知道

答案1
Rinzwind，谢谢你！你让我找到了正确的方向，在你告诉我日志后，我能够更好地研究问题了。我发现许多其他人也遇到了我的问题，我似乎已经通过升级到 Linux 内核 4.4.8-040408-generic 解决了这个问题。显然 4.4.0 存在与我的类似的严重硬件问题。再次感谢。
