Ubuntu 有时会完全冻结

Ubuntu 有时会完全冻结

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: 系统规格

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。
