Hello everyone.
Hope you all are doing well in your life.
I want a small help from you guys. I am trying to change the login screen of gnome40. I am using Garuda gnome. I searched on google but I couldn't found any. They have only solutions for gdm3. But gnome 40 uses GDM 40.1
If anyone can help me I will really appreciate it.
Thank you
Unless something has changed recently, modifying the GDM background is non-trivial. I wrote an application that did it a few years ago but it required modification with every gnome update so I stopped maintaining it.
There are some 3rd party applications that do it but I don't know if they have been updated for gnome 40 yet.
The short answer it is isn't something easily changed.
You should give Gnome Tweaks a try. It allows you to change more stuff than you can normally in gnome. Just search the Add/Remove Softwear and you should find it, or you can type sudo pacman -S gnome-tweaks in a terminal.
You can change the "lock screen" image only. For a multi-user environment, it is not enough, but for a single-user workstation, you only see gdm screen once, at 1st login.
