Re: SDDM don't start
Try putting your video module in the initramfs. I've seen things like this when the system starts up faster than the video driver can be ready.

Re: SDDM don't start
The same happened to me, and I've been using sddm for a long time. I think a recent update broke sddm. I am not yet sure which exact packages caused it.
So far I have tried recompiling sddm against current libraries. It does not help.

I think you've run into a breakage of sddm.
You can use another display manager for the time being until this issue is resolved.
1. Switch to another tty by pressing ctrl+alt+f2, and log in
2. Install another display manager: sudo pacman -S lxdm-gtk3
3. Disable and stop sddm:
sudo systemctl stop sddm
sudo systemctl disable sddm
4. Enable and start lxdm:
sudo system enable lxdm
sudo systemctl start lxdm

Re: SDDM don't start
I tested again, it still does not work. I tried with ligthdm and I have the same problem.In fact, for me to get sddm or lightdm to boot, I must first activate the service, reboot on command line mode and manually launch sddm or lightdm.
if i dont do that, after loading kernel, screen freeze and its impossible to open command line session or do anything...

Re: SDDM don't start
Same thing here, a great answer thank you Arch Forum, any suggestions of alternative display managers in the meantime?
I CAN confirm it was a recent update although I updated an awful lot!

I auto login to kde without a display manager. Automatic login into Xorg without display manager. This works for me since I don't use any other desktop. If you log out, it brings you back to the command prompt. So you can sign in and launch a different desktop if you wish.

Re: SDDM don't start
I've been trying to switch to Nouveau 1.0.14-1 and couldn't get SDDM to start (dmesg prints sddm errors segfault 14, and 4 in libQt5Core.so.5.8.0). It works with the binary driver.
I can't tell if I'm doing the switching wrong or am getting the same behavior, but is anyone with the proprietary Nvidia driver affected?

Re: SDDM don't start
I just want to report that my problem with sddm is gone. I don't know how or when or why. Intel graphics.
There's 1 speculation though: I had kmscon installed, and I had been using kmscon for all my vts, including #1. The day sddm went wrong, I noticed that kmscon was buggy too (cannot switch between vts). So I removed kmscon to use kernel-based vt. Then something got my attention and I stopped investigating.
Days later, I tried to use sddm again and it just worked. So... if you use kmscon too, try uninstalling it. There're instructions on the wiki.
