几周以来，我的 kubuntu 安装经常崩溃。一切都完全冻结。没有鼠标光标，什么都没有。大多数时候，我的机器正在运行繁重的节点任务。4 个核心中的 1 个处于 100%。
我尝试过许多不同的内核但似乎没有任何效果。
$ uname -r 4.11.4-041104-通用
我的 bios 版本是：1.4.17
这是发生此问题时的系统日志:(在这种情况下，它发生在播放 YouTube 视频时）

答案1
似乎是内核问题。安装后：4.11.11-041111-generic 一切正常。已经运行了 2 个月，没有再崩溃。;-)
感谢哈维尔的帮助！
问候，比利
答案2
可以肯定的是，你的视频驱动程序有问题。
尝试使用戴尔支持提供的 ubuntu 14.04 映像
如果问题仍然存在于 14.04 中，可能是热问题？您的型号是 xps 13 9350？
我看到这不是新安装，没有加载 14.04。也许当升级驱动程序时系统开始冻结。
然后尝试更改专有驱动程序。
完毕？
