The login screen runs as a regular unprivileged user 'gdm' (not root) so it does (apparently) require that you make any images world-readable in order for user 'gdm' to be able to read them.
Although I find this slightly surprising. A better design might be for gnome-control-center to copy the image when you configure it, and ensure the copy is always world readable. Because the current design does not seem to be user-friendly... Anyway, this doesn't seem to be a bug so I will close it. ** Changed in: gnome-shell (Ubuntu) Status: Incomplete => Invalid -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1814566 Title: User photo is missing in login screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1814566/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
