我已在笔记本电脑 Dell Inspiron 5000（AMD Ryzen 5 2500U/8 GB RAM/1 TB HDD/Windows 10/39.62 cm（15.6 英寸）FHD/Vega 8 显卡）上安装了 Ubuntu 18.04Inspiron 5575
操作系统会随机冻结，甚至有时没有打开任何应用程序，有时只是打开 Chrome，有 7-8 个选项卡。我检查了内存占用情况，还致电戴尔支持中心。他们确认硬件没有问题。
另外，为了了解更多信息，我有 8 GB 空间和 100GB 文件系统分区，剩余用于备份或其他存储。
我需要确定并解决这个问题。

更新：（2020 年 6 月 3 日）
几个月前，我将 Ubuntu 从 18.04 升级到 20.04 LTS（希望能解决这个问题），很高兴它运行得很好。升级后没有遇到过冻结的情况。我是在升级后使用大约 2-3 个月后写这篇文章的。在这 2-3 个月里，我几乎没有关闭过 3-4 次笔记本电脑（只要我记得）。
我建议所有在 18.04 遇到冻结问题的人升级到 20.4 LTS。因为频繁的死机和强制重启对硬盘来说是不好的。
这不是问题的实际解决方案，因此我将为其他人保留此线程。
答案1
对我来说，结果是谷歌浏览器挂掉了整个系统。我被这个问题困扰了几个月，直到我禁用了 Chrome GPU 硬件加速。
我在今年二月/三月左右应用了此修复程序，此后系统就没有冻结过。
归功于这篇文章：Chrome 在 ubuntu 16.04 上经常死机
答案2
我的系统上也有类似的问题。当我将电脑闲置一段时间时，它会锁定在空闲状态。这似乎是 AMD Zen 处理器上 C6 深度空闲电源状态的一个已知错误。
我创建了一个在启动时禁用此电源状态的服务，并且它已经在我的系统上运行了几周，没有出现任何问题，因此我将其上传到 OBS 供其他人使用。要安装它：
$ wget -nv -O - https://download.opensuse.org/repositories/home:jkist/xUbuntu_18.04/Release.key | sudo apt-key add -
$ sudo sh -c "echo 'deb http://download.opensuse.org/repositories/home:/jkist/xUbuntu_18.04/ /' > /etc/apt/sources.list.d/home:jkist.list"
$ sudo apt-get update
$ sudo apt-get install amd-disable-c6
其他发行版的版本可以在这里找到
或者，您可以尝试在 BIOS 中禁用 C6 状态。不过，如果您的 BIOS 和我的一样糟糕，您可能没有该选项，或者您可能必须禁用所有省电模式，而不仅仅是禁用 C6 状态。
答案3
我在使用 Ryzen 5 3600 CPU 和 Nvidia RTX 2060 的新安装系统（5.0.0-25-generic内核版本）上也遇到了这个问题。安装amd-disable-c6或 HWE 软件包没有帮助，但有帮助的是安装 nvidia 驱动程序。我就是这样做的：
- 添加以下行到
/etc/modprobe.d/nvidia-graphics-drivers.conf
blacklist nouveau
blacklist lbm-nouveau
alias nouveau off
alias lbm-nouveau off
- 添加
nomodeset到文件GRUB_CMDLINE_LINUX_DEFAULT中的变量/etc/default/grub，如下所示：
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"
- 跑步
sudo update-grub - 重启
- 添加 ppa 存储库：
sudo add-apt-repository ppa:graphics-drivers/ppa
- 通过键入 切换到运行级别 3
sudo init 3。如果您在切换到 tty/1 之后看到黑屏CTRL+ALT+F1 - 安装驱动程序
sudo apt-get install nvidia-driver-430
- 重启
从那以后我就没有再出现任何冻结现象。
答案4
自从 16.04 之后更新（或实际安装）18.04 以来，我遇到了同样的问题。问题是，首先，我在管理 Nvidia 驱动程序时遇到了很多麻烦（K2100M 确实是个麻烦制造者）。因此，即使在看电影、编码甚至笔记本电脑关闭时，我也会随机崩溃。我最近通过以下方式将内核更新到 15.0.0.25-generic
sudo apt install --install-recommends linux-generic-hwe-18.04 xserver-xorg-hwe-18.04
从那时起，我就完全没有遇到随机崩溃的问题了。您可以查看我的文章以及。
