disable accessibility on-screen keyboard in login window

[Joao Ferreira Gmail]

Hello all,

my son's netbook uses Ubuntu 10 with gdm/gnome.

Accidentally he activated the "Use on-screen keyboard" accessibility
option at the login screen.

Now, on the right side a zoomed keyboard appears. On the left a smaller
keyboard appears. But I can not access the option to disable it.

I would like to put things back the way they were. Meaning, no on-screen
keyboard. Just the normal login window.

Is there some config file for this ? Is it gconf ?

thanks

Joao
