[SOLVED]Failed to start Light Display Manager

Today I installed Arch on my desktop. So I decided to try several DE's. Firstly I installed gnome-desktop and gdm via

pacman -Syu gnome-desktop 
pacman -Syu gdm
systemctl enable gdm.service

and everything worked fine.
Then I removed gnome-desktop via

pacman -Rscn gnome-desktop 
systemctl disable gdm.service

and decided to install Deepin, I used

pacman -Syu deepin networkmanager lightdm
systemctl enable NetworkManager.service
systemctl enable lightdm.service

then I modified  /etc/lightdm/lightdm.conf file following Wiki page and after reboot I saw this

I tried to google answer but it doesn't help me.
So what should I read or learn to solve this problem? Thanks in advance and sorry for my bad english
P.S. If you need something else, maybe some logs, ask me, I will give it.

Re: [SOLVED]Failed to start Light Display Manager

Couple of things:

1. Not necessarily wrong but nonetheless worth pointing out: ''pacman -Syu'' is the system upgrade switch; if your mirrors are up-to-date, ''pacman -S package'' suffices. See this.
2. -Rscn is generally a terrible idea, as it removes packages higher up in the dependency chain. Again, read the document in the above link.
3. The screenshot gives you a hint: Check the status of your failed service.
4. Read the Code of Conduct and adjust the screenshot in your post accordingly.

Re: [SOLVED]Failed to start Light Display Manager

What is the output of systemctl status lightdm.service? 
Also did you install the lightdm-gtk-greeter package as well as per the instructins on the wiki?

Yes, I'm blind. It helps, thank you.

Thank you for advice. I'll read it.
