Cannot change lock screen background on Ubuntu 18.04
Cannot modify files installed by `snap`18.04 - Cannot change the background color of the LOCK screen, not the Login screenHow do I change background of login screen?Gnome backgroud log in, not change(after change it)Missing lock screen wallpaper in Ubuntu MATE 16.04Desktop doesn't open after selecting a different theme from the Gnome login screenUbuntu 18.04, vanilla GNOME: Force lock screen background to be the same as GDM background?Changes made to gnome lock screen doesn't workGet rid of unity desktop on Ubuntu 18.04How do I change lock/login screen background on Ubuntu 18.04 with 2 displaysAdding a login screen background using .themes folderUbuntu 18.04 - “All shell packages missing” after botched file copyHow to recover missing gdm3 files causing broken login screen on 18.04
Before you mark the question as a duplicate, I read all of the posts regarding this, but nothing helped me. I'd like to change the background picture of the lock screen.
I changed the ubuntu.css and gdm3.css accordingly to
#lockDialogGroup
background: #000000 url(file:///usr/share/wallpapers/minimalistic-gray_00323985.jpg);
background-repeat: no-repeat;
background-size: cover;
background-position: center;
Which results in a change of the Background of the log in screen, not the lock screen. When I press super + L the screen containing time has the correct background. When I swipe it up to tipe in my password, the purple Ubuntu screen still appears. If I click to change the user, the log in screen appears with the right background. I have the same background picture enabled in gnome tweaks for desktop background and lock screen.
I'm running Ubuntu 18.04 GNOME on a TuXedo Laptop. And I use Communitheme - maybe thats the problem?
Any ideas why it doesn't work? (I rebooted multiple times, so that's not the problem.)
EDIT: The output of sudo nano /usr/share/gnome-shell/modes/ubuntu.json is
"parentMode": "user",
"stylesheetName": "ubuntu.css",
"enabledExtensions": ["ubuntu-dock@ubuntu.com", "ubuntu-appindicators@ubuntu.com"]

If it's a PPA install
sudo add-apt-repository ppa:communitheme/ppa
sudo apt update
sudo apt install ubuntu-communitheme-session
then this is the file
/usr/share/gnome-shell/theme/communitheme/gnome-shell.css
When it's a snap install
sudo snap install communitheme
this is the file
/snap/communitheme/1593/share/gnome-shell/theme/Communitheme/gnome-shell.css

Yes, the folderwallpapersexists in that exact directory. Elsewise, changingubuntu.csswouldn't have had any effect on my login screen, but it had. I tried the black color with no effect. Seems like changing thejsonfile, isn't the only thing one has to change.

I did, but it didn't fix the problem. There is no difference in just renaming the file, is there? Why should renaming fix the problem? Thanks for the suggestions anyways. Do you have any more ideas left?

Of course not. I followed your instructions thoroughly. But I don't really see a difference between creating a new file and copy-pasting the content, and just renaming
ubuntu.css and change the name within the .json file. But my knowledge is limited.– jeypeu

I did exactly what you proposed to, but it had no effect.

@PRATAP Exactly, thats the picture I want to use. Hm, I can change the appearance of the background and lock screen both in settings and gnome-tweaks. I'm not a 100 percent sure, how it's called on your system since mine is in german, but it should be something like
Appearancein gnome-tweaks.– jeypeu

I bought it last week, so I assume it's a fresh install. I changed the file, but unfortunately it changes nothing. Maybe it's because I use
Communitheme? Or maybe, because it says I don't have the extension installed to change theShelltheme?– jeypeu

@PRATAP See the updated question above.

snap and apt are two different things.. you can get differences easily by googling.. you can check by opening snap file in the below answer and see the color which is showing at lock screen..
