How to change the lock screen login wallpaper on budgie?

[Morty]

Hello, I’m new on the forum and on the OS itself sorry if it’s an very easy solution for this because I can’t see this option anywhere on budgie settings. I just want to change the lock-screen login wallpaper which is different from the boot login screen, I changed the display manager from lightdm to gdm on the “Select Display Manager” on the “welcome” app, while the login screen from booting/re-booting the system has changed, the lock-screen still stayed the same… I’m not a programmer so if you can explain everything in details it would be appreciated, I also disabled WallStreet control if that matters.
If anyone needs more details please let me know. English is not my main language so sorry for any mistakes!

A crude picture of my lock-screen bellow:

for lightdm look at /etc/lightdm/slick-greeter.conf

I’m not using lightdm right now, changed to dgm, even the background image listed on there is only for the login boot, the endeavourOS default one, different from the one from my lock-screen pic…

You could use betterlockscreen instead. It’s an environment-agnostic screen locker. You can then change your wallpaper to whatever you want.

Not well-versed in Budgie, but from the experience I had with it, it’s a simplified Cinnamon with a side panel. In Cinnamon, your lock screen is based on what your current desktop wallpaper is. So, if your wallpaper changes throughout the day, then you always have a different wallpaper when your screen locks.

Thank you for the rec! But I just found how to change the lock-screen… ooops
Earlier today I disabled WallStreetControl which is the software that changes wallpapers because I’m only using one standard desktop wallpaper, which is completely different from the lock screen one. But now I enabled it again and only used a directory with only one wallpaper in it and clicked on the “Sync to lock-screen” option, I locked the desktop and it stayed the same. Then I rebooted the computer and… Well it worked, thankfully!
Thanks for taking a bit of your time to help me!

Maybe there’s another way, but for now this will suffice.
