任务
晚上回来，开电脑，发现总是进不去系统（这个情况我经常见），但偶尔进系统，识别不了我的外接屏（这个第一次见）。来来回回重启了1h多了还是这个现象。无奈，只能重装驱动了。

现状描述
上一次开机运行nvidia-smi还有显示，但显存占用是0.这次运行，直接没了：
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
运行xrandr，还是和以前一样，没有识别到外接屏：

打开软件和更新，查看附加驱动：
执行情况
我打算先换成nvidia-driver-525-server这个驱动。点击，然后应用更改，出现了如下离谱情况：
关闭也关闭不了。现在重启一次电脑吧。
这会查看显卡驱动，竟然这样了：

sudo apt install nvidia-utils-418-server # version 418.226.00-0ubuntu0.20.04.2
应用和更新中，现在的驱动也变成了一个开源驱动，所以我选择回到525：
还是老错误，出一个大白条。
因为老出这个问题，我就不用他更新了，我用命令行更新。
查看可用驱动：
ubuntu-drivers devices
我就装那个recommended的：
sudo apt install nvidia-driver-535-server-open
然后重启电脑。
不行，没有图形界面了。只能ctrl alt fn f2进入tty界面，然后：
sudo apt install nvidia-driver-525
再重启，解决了。进来了。
