18.04 - Cannot change the background color of the LOCK screen, not the Login screen
Good evening,
I'm trying to change some of the colours of my login screen in my Ubuntu 18.04. I followed some questions here on AskUbuntu, and edited my css files at /usr/share/gnome-shell/theme/gnome-shell.css (I'm using that configuration) - Specifically, I changed the values of .lockDialogGroup to a nicer dark gray.
My login screen is indeed now a nice dark gray instead of that hellish purple.
However, if I lock my computer without shutting down the machine, I still get a different purple gradient, which I haven't managed to change. I'm serching around but since I don't even know what to call this "behind-the-shield" screen, I can't find relevant results.
I suspect the login screen and the lock screen are two different managers altogether.
Here's a short mp4 video of me literally filming my screen, to make you understand which color I'm trying to change:

EDIT: There seems to be a discrepancy between my first-after-boot login screen, and my login-after-locking screen.

"behind-the-shield" screen as you mentioned in question is called unlock screen.
also i understood that somehow your unlock screen background is same as default Ubuntu 18.10 vertical gradient. so below content may look different when you open ubuntu.css file
in your case,
seems to be, you have diverted gdm3 to use /usr/share/gnome-shell/theme/gnome-shell.css as opposed to the default in Ubuntu 18.04 /usr/share/gnome-shell/theme/ubuntu.css
the changes you want to apply to unlock screen can be done by editing this ubuntu.css file.
sudo-H gedit /usr/share/gnome-shell/theme/ubuntu.css and edit the below content as per your need.
#lockDialogGroup {
background: #2c001e url(resource:///org/gnome/shell/theme/noise-texture.png);
background-repeat: repeat; }
for example, i have edited as per my wish like below
#lockDialogGroup {
background: #0000FF url(resource:///org/gnome/shell/theme/noise-texture.png);
background-repeat: repeat; }
and the result is

This does not work. As I said earlier, I've already changed the#lockDialogGroupCSS entry in my enabled .css file. It is indeed the gray color that I see in my login screen. My lock login screen is separate, and has a purple color still! When I boot up my machine, the login screen is fine and shows the color I've selected (#3f546b). Only after using Lock does this purple screen come up, and I'm beating myself trying to find the .css file that controls it.
