At first Instead of my SDDM I would just see an after image of what was last displayed on screen. But if I typed in my password and pressed enter, it would let me in just fine. Then after following some suggestions from users in r/Kubuntu I’ve made a bit of progress. Now when I boot up my computer instead of the SDDM being invisible, it now doesn’t load at all, from there I switch to tty3 then back to tty2 and then log in through the terminal. After that I run startplasma-wayland and then I have access to my desktop. The post where all this went down - https://www.reddit.com/r/Kubuntu/comments/1nvreuo/sddm_not_rendering/

Does anyone know a fix? I would like to be able to see my login screen.

Here’s my specs in case that would help - https://i.imgur.com/XtC43zw.png

And here’s my journalctl output after booting and launching plasma - https://pastebin.com/nnGsWebd

try updating your packages and see if that helps, also can you do a systemctl status sddm

I think this might have something to do with the issue but I'm not sure

sddm-helper[1790]: Failed to write utmpx:  No such file or directory lines 1-25/25 (END)

No, this error is harmless. There is a Debian bugreport to remove even logging that error.

Is this the sddm status you've posted after starting it manually?
