![Ubuntu 18.04 LTS 更新后运行非常慢(双启动 Ubuntu 和 Windows 10)](https://linux22.com/image/1067013/Ubuntu%2018.04%20LTS%20%E6%9B%B4%E6%96%B0%E5%90%8E%E8%BF%90%E8%A1%8C%E9%9D%9E%E5%B8%B8%E6%85%A2%EF%BC%88%E5%8F%8C%E5%90%AF%E5%8A%A8%20Ubuntu%20%E5%92%8C%20Windows%2010%EF%BC%89.png)
我已经运行 Ubuntu 18.04 LTS 和 Windows 10 双启动大约 8 个月了,但没有任何问题。昨天我收到了关于 ubuntu 更新的通知,我继续更新它,但重启电脑后,Ubuntu 运行非常慢,风扇一直像 Hussein Bolt 一样转动,蓝牙无法打开,甚至没有显示其正常位置。但当我在 Windows 中启动并重新启动回 ubuntu 时,速度似乎没问题。我尝试修复 grub、软件包等,但似乎什么都不起作用。请帮我解决这个问题,因为它让我的生活变得很糟糕。谢谢
