I’ve tried changing lock and login screen but I can’t. I’ve tried changing sddm settings but nothing works. When launching sddm from terminal it works, but nothing changes when I try to make any changes. The only change that did something was changing the background picture, and it didn’t worked well and just removed the bg pictures (see attached image, sorry for the poor quality, had no way to screenshot it X3)
Thank you for further help and have a great day
What does the contents of /etc/lightdm/slick-greeter.conf look like?
If that file doesn’t exist, create it and add the following entries:
[greeter]
background=/path/to/your/wallpaper.jpg
Note: It is recommended to place your wallpapers inside directories that the lightdm user can access; for example, /usr/share/pixmaps
Other configuration options are available as well. Here is a list of all configurable options for slick greeter:

Where is your wallpaper file located?
Do you mean you’re trying to change a greeter or are you just trying to change the background? EndeavourOS uses slick greeter and lightdm by default.
@MoreOwO says sddm is being used, but I agree with @anthony93, the image looks like lightdm.
So I guess we need to establish which Desktop Manager is in use. Please show the results of the two commands
pacman -Q sddm
pacman -Q lightdm
Pudge
Indeed. And if memory serves, EOS uses lightdm by default.
I hate to get nit picky, but the Desktop Manager installed by default depends on which Desktop or Window manager is installed. However, most of them do use lightdm & lightdm-slick-greeter.

EDIT:
The screen shot looks like the password entry box has the LXQT logo?
There is also this GUI tool for editing Lightdm: https://aur.archlinux.org/packages/lightdm-settings
I’m using KDE as default windows manager. I don’t know if i’m using lightdm or sddm, i just know both were installed.
$~ yay -Q sddm
sddm 0.20.0-1
$~ yay -Q lightdm
lightdm 1:1.32.0-4
Content of slick-greeter, which is not really accurate with what i can notice on my logging screen.
[Greeter]
background=/usr/share/endeavouros/backgrounds/endeavouros-wallpaper.png
draw-user-backgrounds=false
draw-grid=true
theme-name=Arc-Dark
icon-theme-name=Qogir
cursor-theme-name=Qogir
cursor-theme-size=16
show-a11y=false
show-power=false
background-color=#000000
SDDM seems to be way more stylable so if I can switch to it (if I’m not using it), it would be pretty nice (ofc, correct me if i’m wrong)
Please forward me to docs I could use to do that.
I don’t know if it’s related, but when running sudo sddm from terminal, it shows sddm right, but when I try to login, it just go black and does nothing.
Thanks
please show the output of the following. This will tell whether Lightdm or sddm is enabled.
systemctl status sddm
systemctl status lightdm
Pudge
This sounds like lightdm is enabled and sddm is not.
You can get the answer with only one command:
systemctl status display-manager
The above name is an Alias/link which is used by all DMs whenever they are enabled/started. 
LightDM is in use
$~ systemctl status display-manager

If you prefer sddm, you need to disable lightdm and enable sddm
sudo systemctl disable lightdm
sudo systemctl enable sddm
then reboot.
If you want to configure lightdm-slick-greeter, then you need to look at the first post of this Topic
Pudge
I’ve tried doing that, but then nothing would show up and i would need to hold Ctrl+Alt+F2 while bootup in order to have sddm. otherwise, i was stuck and i had to force reboot my computer (you can’t turn it off by clicking on the power button, idk why it’s dumb)
It sounds like sddm is launched on tty2 instead of tty1. Can you post the contents of sddm’s config file (/etc/sddm.conf)?
Pay attention to the MinimumVT= option under X11 section. Is it set to 2?
[Theme]
Current=catppuccin-macchiato
I had to create it by hand as it wasn’t created. Should i add this ?
[X11]
MinimumVT=1
I just went through the Arch Wiki. That setting is no longer available.
The fact that you have to switch to tty2 to see sddm means that something else is running in tty1 - most probably lightdm (since you have it installed).
If you don’t plan on using lightdm, just uninstall it. And then make sure that sddm is enabled. According to Arch Wiki, sddm should work out of the box.
I’ve uninstalled lightdm and enabled sddm and now, i can’t loggin in any tty. It’s even harder for testing as the window to change tty is like, 10s (during cleaning of passed forced shutdown). I’ve tried 1 2 & 3 and neither of them are working.
If you’ve enabled the service, it should launch at boot. If it doesn’t, it might have something to do with the graphics drivers. Are you using nvidia? If the nvidia drivers are loaded after your display manager, you will end up with a black screen and nothing else. To prevent this, you need early KMS, which ensures that the nvidia kernel module is loaded at the earliest possible occasion.
No, my laptop is under AMD. I have the plymouth animation and then, it ends and it just shows me what was previously on my screen before the animation.
The HP logo?
