缘起：公司电脑要安装加密软件，对于ubuntu20.04.5使用linux-6.8的内核安装加密软件失败。
售后要求切换到linux-5.15了。【内置的摄像头在guvcview下没有声音了/有些驱动没有了。】

ubuntu开机卡在/dev/nvme0n1p2: clean 进入不了图形界面 - 20.1117

主要步骤：

1、Ctrl+Alt+F2进入命令行，输入用户名、密码。
2、sudo vi etc/default/grub, 照着那篇博客里讲的改好
3、sudo update-grub
4、reboot

二）、修改grub 引导项（很多人通过这个解决了，但是这招对我没用）

在黑窗口里面（Ctrl+Alt+F2-7都行，输入用户名、密码），输入
sudo gedit /etc/default/grub

找到quiet splash并在后面添加nomodeset；修改前：
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

修改后：
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset“

然后输入【在启动菜单的recovery模式中】
sudo update-grub
再重启就行了。
