how to change the keyboard layout used in log-in screen?

[ubunt2 at gmail.com]

the login screen is currently set to DVORAK layout. How can i make it
QWERY keyboard layout? there's no option to change keyboard layouts in
the login screen. so i guess it must be chosen beforehand. where?

I, original user, uses Dvorak. The new user account i set up uses Qwerty.

Actually, I wouldn't mind setting it to QWERTY now. Because in a few
hours, the pc is going to its new owner (who uses qwerty).
