2022-06-30 lightdm启动失败
lightdm 启动不了，一般情况下是显卡驱动安装的问题。这次也不例外。 现在我就来说说我出现该问题的经过。

经过升级后， 而显卡 nividia 驱动的dkms 模块没能正常升级, 经过多方尝试发现我的显卡 780 已经不再受支持了(18.5以后), 于是我尝试才有 nouvea 驱动进行;

重启就解决了。
xorg
The X.Org project provides an open source implementation of the X Window System. The development work is being done in conjunction with the freedesktop.org community. The X.Org Foundation is the educational non-profit corporation whose Board serves this effort, and whose Members lead this work.
Xorg (commonly referred to as simply X) is the most popular display server among Linux users. Its ubiquity has led to making it an ever-present requisite for GUI applications, resulting in massive adoption from most distributions. See the Xorg Wikipedia article or visit the Xorg website for more details.
lightdm 启动不了， 而且报 lightdm 重启速度过快; 看了 wiki.archlinux.org 中关于 lightdm 的描述后， 得知 lightdm 很可能没有 greeter 导致的。（因为我在之前想删除所有的与 deepin 相关的安装包， 这时我也删除了 deepin-session-shell ）
