我最近在笔记本电脑上安装了 18.04 LTS ubuntu。我每天都会遇到这个问题。我的笔记本电脑使用几个小时后就挂断了，什么都不能用，甚至鼠标和键盘都不能用。我已经运行dist-upgrade并安装了图形驱动程序，但什么都不起作用。
需要帮忙

按照@ElderGeek 的建议。我已经安装了lm-sensors。我看到温度在 43 到 48 摄氏度之间。
这是我的系统信息：

正如@WinEunuuchs2Unix 所建议的。我运行journalctl -b-1后发现了这些红色线条。我已将其逐一复制粘贴到下面：

答案1
2018 年 6 月 14 日更新
基于此 ArchLinux论坛主题看来您需要添加：
amdgpu.dc=0
到你的/etc/default/grubLINUX 行之后quiet splash。然后运行sudo update-grub。
作为 Ubuntu 18.04 的新安装，您是幸运者之一，可以使用它journalctl查看上次启动（锁定）。使用：
journalctl -b-1
然后按下End键跳转到 EOF（文件结束）。在我上次成功的启动中，它显示：

您需要在其中查找错误消息。
您可能必须使用Page Up密钥才能看到它们。
当您找到了所寻找的内容（或放弃寻找）时，按Q退出。
如果过热导致关机，您可以安装 Intel Powerclamp：防止 CPU 过热
此外，lm-sensors您可以使用以下命令直接从命令行获取所有热区域的温度读数：
$ paste <(cat /sys/class/thermal/thermal_zone*/type) <(cat /sys/class/thermal/thermal_zone*/temp) | column -s $'\t' -t | sed 's/\(.\)..$/.\1°C/'
INT3400 Thermal 20.0°C
SEN1 44.0°C
SEN2 52.0°C
SEN3 64.0°C
SEN4 59.0°C
B0D4 73.0°C
pch_skylake 76.5°C
x86_pkg_temp 73.0°C
以摄氏度报告并删除最后三个零。
答案2
除了使用 amdgpu.dc=0 内核选项的解决方案外，升级到基于 linux 4.18 的 ubuntu 18.10 内核已修复此问题，并且不再需要在内核启动中使用此 amdgpu.dc=0 参数来使图形正常工作。（AMD Stoney 硬件）
答案3
内核已经安装好了，对吗？;-)
确定你的内核版本：
uname-ar
然后搜索合适的 kernel-headers 包，kernel-headers 版本要一致，然后安装即可。
您也可以在终端中输入：
sudo apt-get 安装 linux-headers-$(uname -r)
重启
重启后，Linux 崩溃的次数会减少。
