Slightly tricky; SDDM decided to add code themselves into show a fallback icon they provide from /usr/share/sddm/faces This path overridable in sddm.conf So now instead of getting a file path, or nothing we always get something. From Breeze's POV we have no good idea if we're loading the user's face or a stock icon. Even if we did somehow add code in breeze, that would only break SDDM's config option. At /best/ breeze could supply the files into the same directory structure as /usr/share/sddm/faces and we tell distros to change that path.
(In reply to David Edmundson from comment #2) > This path overridable in sddm.conf Why not then make the KCM change the path on theme change? Would this also fix displaying custom per-user icons set in System Settings?
SDDM is still showing a default icon which is not Breeze-themed. It does that even when there is a user icon set (symlinked to ~/.face.icon). Is that a bug in SDDM or the Breeze theme?
This was an issue with the old theme.
