I want to change the Ubuntu Budgie login screen background to the one I'm currently using on my account; Just like it was with the previous Ubuntu versions with Unity with the draw-user-backgrounds option.
I already tried searching for that option or anything with "background" on it with dconf-editor but found nothing.

Open the Login Window app in the menu under Administration.

If it is missing from the menu then install it:

sudo apt install lightdm-settings

Enter your credentials when prompted. Click on the default background image icon, then navigate to /. Click on home>username>Pictures. Select your desired pic, click Open the in upper right corner, close the app. Log off and you will see your desktop background on the Login screen.

Thanks.

    Is there some dependency of lightdm-settings that isn't specified in the package? On my system, which was upgraded from 16.04, I've installed lightdm-settings, but when I launch the Login Window menu item I get prompted for my password but then no window appears. – rakslice Sep 8 '18 at 22:24
  • @rakslice I experience the exact same thing, but my system is a clean install. – beruic Sep 27 '18 at 19:36

    lightdm-settings doesn't seem to work in 18.04, it just causes multiple crashes in python on my machine each time I try to open it. – JamesBB Oct 1 '18 at 12:07

I have simple Ubuntu 18.04.1

In my opinion the best way to do this:

step1: make backup of the file /usr/share/gnome-shell/theme/ubuntu.css - if you have another desktop for ubuntu you can find file ubuntu.css just using command locate ==> locate ubuntu.css

step2: vim /usr/share/gnome-shell/theme/ubuntu.css and find part below

   #lockDialogGroup {
   background: #2c001e url(resource:///org/gnome/shell/theme/noise-texture.png);
   background-repeat: repeat; }

step3: change it to

   #lockDialogGroup {
   background: #2c001e url(file:///usr/share/backgrounds/warty-final-ubuntu.png);
   background-repeat: no-repeat;
   background-size: cover;
   background-position: center;
    }

calrification: as you can see, we changed
"background: #2c001e url(resource://" part to the ==> "background: #2c001e url(file://"
and then set up path for the image.
I used /usr/share/backgrounds/ for the path with image. Also I added some css properties to center the image.

This is only the css file configuration. That's it)

I tried all of those and none worked. This does, for sure:

As root user, just copy your_image.png to /usr/share/backgrounds and ....

# cd /usr/share/backgrounds
# cp warty-final-ubuntu.png warty-final-ubuntu.png.stock
# rm warty-final-ubuntu.png
# ln -s your_image.png warty-final-ubuntu.png
# reboot

...where your_image.png is the name of the actual image you want to display. The warty one is big: 4096 x 2304. I matched mine to the same size.

lightdm-settings is a good choice, as well as, you can try

sudo xhost +SI:localuser:lightdm
sudo su lightdm -s /bin/bash
dconf-editor

In dconf-editor find x/dm/slick-greeter you can edit whatever you want

  • Run Terminal with Ctrl + Alt + T
  • Run nautilus with sudo by doing (sudo nautilus) - without the brackets
  • Copy your desired background image to /usr/share/backgrounds/
  • Go to /etc/alternatives/gdm3.css and open with Text Editor

Change This

  #lockDialogGroup {
  background: #2c001e url(resource:///org/gnome/shell/theme/noise-texture.png);
  background-repeat: repeat; }

To This

  #lockDialogGroup {
  background: #2c001e url(file:///usr/share/backgrounds/yourimage.png);
  background-repeat: no-repeat;
  background-size: cover;
  background-position: center; }

Click 'Save' when you're done.

    It doesn't help with the "login screen". – Omar Tariq Aug 14 '18 at 9:26
  • @OmarTariq Totally agree with you. In 18.04 – SaidbakR Oct 21 '18 at 20:39
