Not difficult.  You use the standard GTK+ API for toggling full-screen
mode (gtk_window_fullscreen).

If you're talking about screen blanking, then the N800 counts seconds
after the last user event (tap/hardware button press).  If your
application wants to keep the screen on without user activity, it should
periodically call osso_display_blanking_pause (once every 59 seconds).

A better idea may be to call osso_display_state_on after the progress
bar is completed.  That will save battery, and let the user see when
your operation finishes.
