Lock-screen does not enable one to switch keyboard layouts

[Raphael Mankin]

First, I am not quite sure where the problem lies: in the power manager, gnome-screensaver or xfce-screensaver.

I use keyboard layouts in more than one alphabet. If the screen-lock happens when I am using a non-latin alphabet the unlock screen gives me no way of switching keyboard layouts. I have to use a tty login to kill the session, or reboot.
