Yes, that is the case. This has been true for quite some time, it uses the file /usr/share/backgrounds/warty-final-ubuntu.png no matter what one does.
If you replace that file with a new pic then the greeter will use the new pic.
No. That wasn’t the case on bionic several updates ago (or with ubuntu-unity-amd64.iso) at-least for single user.
I think It has something to do with permissions. For example with latest g-c-c 3.28 creates ~/.cache/gnome-control-center/backgrounds/ with root. These settings are also important
gsettings set com.canonical.unity-greeter draw-user-backgrounds true
gsettings set org.gnome.settings-daemon.plugins.background active true
But even after fixing permission the issue exists. Though /var/lib/AccountsService/users/ properly shows the backgrounds section.
I have started experiencing this problem since updating gnome components to 3.28
I’ve seen this for quite some time though maybe because I don’t use nautilus to handle desktop was a factor…
Certainly doesn’t work now.
As far as dconf/gsettings for unity-greeter, those are useless from a user standpoint & have been for long time
I’ve been putting off upgrading to bionic beta as I’m a bit confused of what to expect in terms of migration from 17.10 and unity, and I use this laptop for work. Will we need to add a PPA, or are you guys testing the packages in the universe repo?
