我的电脑通常运行速度非常快（对我来说），但有时开始运行非常慢（这是第三次）。我的系统在 ssd 驱动器上。我读到可能是 ssd 驱动器坏了。我检查了：
df
结果：
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sdb5 114336932 42097068 66388780 39% /
/dev/sdb1 523248 12 523236 1% /boot/efi
和 ：
sudo smartctl -a /dev/sdb1
结果：

============== 编辑 ============
鼠标指针移动很慢，窗口刷新很慢，散热很吵，这些迹象表明这是显卡问题，CPU工作很重。
答案1
这是由错误的显卡驱动程序引起的。我正在更新 Ubuntu，但有些东西发生了变化。我更改了驱动程序，它运行良好。SSD 驱动器有错误，所以我打算更换它（但这不是瓶颈）
