It's not a trick, Neon does not know where his avatar, must specify.
Maui knows where the avatar if it is in .png format.
Example settings is from ARCH help.

I just installed KDE neon with plasma 5.9. Long story, but bottom line, I can not set up user avatar for ssdm to use in login screen.

There is no /etc/sddm.conf, should I make that config file? In kde menu there is my profile picture. In logout/power off menu from kde, there is also my profile picture, but when restart system, there is no profile picture.

Yes, just like alideda said.
Works for me for KDE Neon 5.9.

edit --->/etc/sddm.conf

Code: Select all

[Autologin]
Relogin=false
Session=
User=

[General]
HaltCommand=
RebootCommand=

[Theme]
# Enable display of custom user avatars
EnableAvatars=true
Current=breeze
CursorTheme=breeze_cursors
#FacesDir=/usr/share/sddm/faces
FacesDir=/home/yourusename/  <-------

[Users]
MaximumUid=65000
MinimumUid=1000

ServerArguments=-nolisten tcp -dpi 192

OK, I added sddm.conf and changed to match my home dir and now works fine. Thanks

Is there a way to achieve this if you have more than just one user?
By the way, what was wrong with the old sddm login to change it into this state?

I know this is an old thread, but FWIW I was able to get my icon on the login page simply by adding the image to /usr/share/sddm/faces/ and renaming it [myusername].face.icon.

In other words, if your user name is 'bob', you would rename the image to bob.face.icon
