我以前使用 Ubuntu 16.04 时也遇到过同样的问题。最近，我全新安装了 Ubuntu 18.04，但仍然遇到同样的问题。当它发生时，键盘也不工作，我无法切换到任何 tty，也无法重新启动 PC，所以我应该进行冷重启。
我的机器是双启动的，Ubuntu 和 Windows 10。我想知道我的电脑是否有问题，或者只是 Ubuntu。系统规格在附图中：

您可以删除并重新创建 ubuntu 的交换文件。它位于根目录中。
尝试以下命令：
swapon——显示 sudo swapoff -a /swap文件 sudo fallocate -l 4G /swap文件 sudo mkswap /交换文件 sudo swapon/swap文件 swapon——显示
我很高兴地报告说，自从我这样做以来，ubuntu 就再也没有冻结过。
