Ubuntu 15.10,挂起/恢复后挂起。Inspiron 7559

经过一番努力在我的 Dell Inspiron 7559 上安装 Ubuntu 15.10 之后,我现在正在解决一两个问题。

我尝试 Ubuntu(我通常使用 Fedora)的主要原因是因为 Fedora 在一些与硬件相关的方面让我失望。其中之一就是挂起。不能挂起的笔记本电脑有点麻烦。每当我想把笔记本电脑扔进包里去开会或做其他事情时,我都必须关机。Ubuntu 似乎处理得更好。Fedora 在其他硬件上也一样,但 ubuntu 的实时 USB 似乎可以很好地挂起/恢复我的笔记本电脑。

好了,我已经完全安装好了。我必须按照我在这里找到的另一个建议安装 Nvidia 专有驱动程序。一切都搞定了。

我现在面临的问题是,当我暂停系统时,无论是通过关闭盖子,还是从右上角的齿轮/电源菜单中选择暂停,它都会正常暂停。系统进入睡眠状态。问题是,它不会在没有崩溃的情况下恢复。键盘重新亮起。电源灯重新亮起,屏幕恢复,但大多数时候它甚至不给我 GUI,甚至鼠标光标,它要么保持黑色(但电源打开/背光)要么只是在屏幕上显示内核转储。此时我必须强制关闭系统。

/var/log/syslog 在崩溃时给我提供了大量输出。有很多重复的数据,我试图将其减少一点。最后的跟踪不断重复,直到我关闭系统电源。
