19.04 Disco Dingo User Avatar and Login without using password

[dstudio101]

I'm a heavy desktop user. And I'm managing a couple of lubuntu desktop for 'public' use.

I like the new Lubuntu 19.04 Disco Dingo very much because it is way way way much faster than its predecessors. Like I said, I'm a desktop user so this is a very very nice experience.

--Previous Lubuntu 18.xx boots really slow -- while Lubuntu 19.04 Disco Dingo is very fast even on a fairly new mainstream desktop/laptops -- core i3-i5 with 4GB RAMs and equivalent.

I hit a few snags while configuring my desktops to use the new version 19.04 Disco Dingo -- mainly

1. adding a user avatar
2. user can click login without using a password
3. configure login wallpaper

This is my immediate concern -- as other functions are working fairly as before. I did not see GUI for configuring the above mentioned -- the previous version has a GUI to configure these.

Please let me know if you have any ways of achieving these. I can follow instructions upto to using a terminal to tweak config files using text editors...

Thanks,

Ben

Configuration of login screen is done at: /etc/sddm.conf
My configuration is:

dmn@Sydney-VM:/etc$ cat sddm.conf
[Autologin]
Session=lxqt.desktop
User=dmn

[Theme]
ThemeDir=/usr/share/sddm/themes
Current=elarun
FacesDir=/usr/share/sddm/faces

The autologin should be self-explanatory. Just add in the user(s)
As far as I know, backgrounds are part of a theme. sddm themes can be installed from Ubuntu Repos. Current= contains the name of the theme to be used.
User icons can be placed in folder indicated by FacesDir= . Each is a file with name like username.face.icon. I think they should be 256x256 px PNG file.

That's it.
