archlinux+dde Failed to start Light Display Manager.(虚拟机)

虚拟机安装archlinux+dde,前两天因为更新了python3.10.1导致开机黑屏，今天更新了一下发现lightdm又不能启动了。

你不会是没装 xorg-server 吧？

哇，大佬啊:lol:

我是虚拟机装了个基础Arch，后面的桌面环境安装都是克隆基础镜像然后再安装的，结果克隆了太多次，把xorg和xorg-server都忘了装了

不过又回到之前的那个问题了，开机黑屏。了解点，但是不知道怎么构建

我想着虚拟机不装显卡驱动应该也是可以的吧，之前都没有安装过，我尝试装一下，感谢大佬指导

试了一会，这个xf86-video-之类的都安装了，更新了optimus-manager还是不行，老老实实用kde了，再次感谢大佬

死马当活马医，实在是没办法了，都试一下。因为更新前确实是可以用的，更新完了以后就出现开机黑屏这种情况了。

Re: archlinux+dde Failed to start Light Display Manager.(虚拟机)

我的机器正常更新也有同样问题，再次更新时先忽略所有的python包就好了，等下次再升级python
