Can't change sddm login screen

[Jonathan Ryshpan]

I believe I have used
   System Settings->Startup and Shutdown->Login Screen (SDDM)
correctly.  I
 * set the theme to Breeze
 * click on Background
 * click on the green image
 * choose a local file
 * click  Apply
The green box is replaced by a thumbnail of my chosen image.  

However there is on effect on the login screen and when I start over
at 
   System Settings->Startup and Shutdown->Login Screen (SDDM)
the image is gone and the green box has reappeared.

What's (not) happening?  Maybe a missing configuration directory?  
No easy to find error messages.

Thanks - jon

My guess is that you need to restart sddm. I believe it only looks at
that stuff on startup. Most DMs don't restart upon login or logout, they
keep running.

I've just done this on an F28 fully updated VM.  And my experience was quite
different.

set the theme to Breeze
click on Background
select load from file and pick file
click Apply
enter root pw at prompt
logout
new background is displayed

It's all just as you say.  

The problem is that I had thought that the lock screen and the login
screen were managed by the same function in System Settings.  They are
not.  I had tested changes to the login screen by seeing whether they
appeared in the lock screen, which (of course) they didn't.

Thanks to all for your help.
