login screen very long to start, then keyboard layout fallback to qwerty

[laulau]

sometimes login screen is long to start (this time it was fstrim slowing down disks), then I must enter my password in qwerty (instead of azerty).
desktop is ok (azerty).

seems that the bug disappears with all gnome extensions uninstalled.

I don't think it's a duplicate because I'm only using french azerty keyboard layout for all users at this time. but, the system was installed with qwerty layout.

the bug just happened to me this morning, and I haven't any gnome extension installed.
