No avatars on login screens

I think there may be more than one issue though.
Was this before or after you had changed the FacesDir parameter in your /etc/sddm.conf file?
When you added moi.face.icon to /usr/share/sddm/faces, did you remember to change the ownership and permissions of the file to the system default values?

Code:

Owner (root) - read - write
Group - read
Others - read

Last but not least, is moi the user name you would type to log in via cli?
This usually matches your home directory name.

Re the "changed the FacesDir parameter in your /etc/sddm.conf file" question, i can no longer remember. Today i had another try, in one of my Maui VMs [sddm.conf is default; unedited by me]. 

No "moi" is not my real name, & is not my username in any of my Maui's, but when online i prefer to retain my anonymity by substituting my name with "moi". I certainly used my proper username, not moi, when i manipulated those various face files.

For today's VM test i created a new file in /usr/share/sddm/faces, as below. After rebooting the VM, the login screen continued to have a blank icon only. You can see that this new file is a real file, not just a symlink back to my /home [given as we established, that's encrypted hence unavailable to SDDM before login]. Have i still misunderstood your meaning?
