Settings >
Language and Region >
Manage Installed Languages >
Apply System-Wide (Use the same language choices for startup and the login
screen)

Title:
there is no way to set the keymap / keyboard layout on the login
screen
Status in Ubuntu:
Incomplete
Bug description:
While there is an accessibility menu on the login screen, there is no
way to set the keyboard layout at the login screen.
This is particularly annoying when an issue like bug 877371 occurs
or when multiple users with different layouts use the same device.
