Problem installing SDDM

---

Hi there

I’m having an issue with trying to switch from lightdm to SDDM. I have installed SDDM and ran

sudo systemctl disable lightdm
sudo systemctl enable sddm

It then tells me that the symbolic link has been created. I then reboot the computer but after getting to the black screen it just hangs. I can use ctl-alt-f2 to get into the command line where I can switch back to lightdm and my computer will boot again.

Does anyone have any ideas why this may be the case?

It seems to me that you did everything right…
Just in case try again:
sudo pacman -S sddm sddm-kcm
sudo systemctl enable -f sddm
reboot

And if you find the same error again try:
sudo systemctl start sddm
see if there are errors…

i would suggest to completely uninstall “Antergos-lightdm” to get sddm working well!

sudo pacman -Rsc lightdm lightdm-webkit2-greeter light-locker

disable all DM’s and first boot into cli > login as root > start sddm manually:

sudo systemctl disable sddm

reboot

login as user to TTY3 [Ctrl+Alt+F3] and start the journalview:
journalctl -f

open TTY4 [Ctrl+Alt+F4] login as root and start sddm:

systemctl start sddm

if this is working you can automaticly enable sddm systemctl enable sddm
If not get status:

systemctl status sddm

Go back to TTY2 and see what goes wrong…

Thanks for your help @joekamprad and @fernandomaroto. It turns out that it was that I hadn’t downloaded the sddm-kcm package as well. I had looked up sddm on the arch wiki and didn’t notice anything about having to install it so I didn’t. Thanks
