我正在运行 HP Zenbook:
- i7处理器
- 32GB 内存
- 1TB固态硬盘
等离子版本:5.18.5
截至昨晚,在 Kubuntu 上执行一些更新后,我的桌面 shell 变得非常缓慢且无响应。
例如,如果我单击“应用程序”菜单,单击后大约有 1 分钟的延迟。
我目前必须在终端中打开一些东西
弹出错误并显示以下内容
安装在“/”的文件系统没有响应
当我查看 HTOP 时,我看到 Slack、Firefox 和其他应用程序使用了大量红色虚拟内存
我的磁盘使用情况也还可以

运行这个命令systemd-analyze;systemd-analyze blame --no-pager
我得到这个输出
