Ubuntu 21.04冻结

Question

在每次启动和重新启动之后，我的Ubuntu21.04工作正常。然而在3-4个小时后，它“结冰了”。除了强制重新启动什么都没有帮助。如何避免后者？

终点站运行：

首先，最有价值的东西应该在硬盘上(例如，无线电)和每日修改(关闭互联网)。安装工具也要准备好。当结冰不好，建议没有得到，然后强制关闭，插入安装工具，启动时按F2。从启动菜单中选择上述工具并重新安装系统。更喜欢LTS版本。小心利维帕奇。在我的案子里起作用了。

你没有足够的内存或者交换空间。

              total        used        free      shared  buff/cache   available
Mem:          3.5Gi       2.2Gi       243Mi       278Mi       1.1Gi       832Mi
Swap:         2.0Gi        17Mi       2.0Gi

我们会把你的交换数量从2G增加到4G，看看这是否有帮助.

注意:不正确地使用rm和dd命令会导致数据丢失。建议复制/粘贴。

在terminal..。

sudo swapoff -a           # turn off swap
sudo rm -i /swapfile      # remove old /swapfile

sudo dd if=/dev/zero of=/swapfile bs=1M count=4096

sudo chmod 600 /swapfile  # set proper file protections
sudo mkswap /swapfile     # init /swapfile
sudo swapon /swapfile     # turn on swap
free -h                   # confirm 4G RAM and 4G swap

使用sudo -H gedit /etc/fstab或sudo pico /etc/fstab编辑/etc/fstab。

确认/etc/fstab中的/swapfile行.并确认没有其他“交换”线..。用这一行的空格..。确认没有标签..。

/swapfile  none  swap  sw  0  0

reboot                    # reboot and verify operation

更新#1:

重新安装Ubuntu以解决问题。
