![Kubuntu 16.04 系统经常崩溃](https://linux22.com/image/1148359/Kubuntu%2016.04%20%E7%B3%BB%E7%BB%9F%E7%BB%8F%E5%B8%B8%E5%B4%A9%E6%BA%83%20.png)
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?
