如果启动过程中也是黑屏，先检查能否进入BIOS以判断是否为硬件问题

启动一切正常，就是不能彻底关机

关机后会显示关机画面，屏幕也会黑，但会听见风扇在转

电池过段时间会没电

建议备份数据后全新安装系统

$ cat /etc/default/grub                                                            ok | at 09:14:53

$ sudo update-grub

排查问题：
1、编辑 /etc/default/grub 文件，将 GRUB_CMDLINE_LINUX_DEFAULT 一行设置为空；
2、使用命令 sudo update-grub 更新引导菜单；
3、重启查看日志

参考连接：https://bbs.deepin.org/post/229075，查看是否是相同的错误

按照上面做了，

但我这里在日志工具里看不到任何错误信息

系统，内核，开关机等都是正常的。

不想重装，打算试试降内核

试了前一个版本的内核，可以正常重启关机

用了5.10.83就不行

linux-headers-5.10.60-amd64-desktop
linux-headers-5.10.83-amd64-desktop

跟我的情况一样啊，我的也是AMD处理器，也是降到5.10.60可以正常关机、待机了。

更新到5.15试试

用 下面命令安装了5.15好多gpu驱动都没有

不过升级完确实可以正常关机了。

sudo apt update && sudo apt install linux-image-5.15.6-amd64-desktop linux-headers-5.15.6-amd64-desktop
