Cant get rid of LightDM (cinnamon)

Ask Fedora
,
1

Hello guys
I’ve installed Fedora Rawhide Cinnamon
uninstalled Cinnamon and LightDM
installed KDE and SDDM
after i reboot the system it still uses LightDM to manage the first login somehow
when i press Meta+L it logs out to SDDM
apperently the lightdm.service dosnt exist, /etc/lightdm is empty and theres no packages for lightdm or cinnamon
any ideas how could i purge it entirely from the system ? its pretty annoying ngl

And before you ask why i didnt install the KDE edition in the first place ?
at the moment of downloading there was no KDE version only KDE Mobile

I hear you when you say you uninstalled lightdm.
So I don’t understand how it can still manage the first login,
just to be sure, can you run

sudo dnf remove lightdm

and post the results?

If you ever can’t find an iso at one place, you can always get it from the links through https://mirrormanager.fedoraproject.org/

You could skip SDDM and get with the new Plasma Login Manager

5

it says package already isntalled
(Plasma 6.6 installed by default)

6

What does

systemctl status display-manager.service

return?

7

And after running

sudo systemctl enable --force plasmalogin.service

and rebooting?

8

Back to SDDM - did you enable the service after installing SDDM?

sudo systemctl enable sddm.service -f

9

it says SDDM is the enabled one

10

Did you run

systemctl stop lightdm.service
systemctl disable lightdm.service

11

“Failed to stop lightdm.service: Unit lightdm.service not loaded.”

12

You could try

  1. reinstalling lightdm,
  2. enabling it,
  3. disabling it,
  4. removing it.
  5. enable plasma login or sddm.

it seems like plasma login manager

18

It looks like SDDM (or possibly plasma login which is basically sddm)

Why do you want to get rid of it? It looks good.

20

well than why my normal login isnt the same as meta + L ?
also because it set to auto login and still asks for password
and its in different language than my KDE xD

SDDM looked like this on Fedora 43 even on first login btw
i think the 2 arent the same thing now, or just plasma 6.6 bug
