Answer 1

Provided you are using Gnome on Ubuntu

import os

os.system('gnome-screensaver-command –-lock')

Answer 2

Is there any reason for the main class to be a thread? I would make it just a normal class, which would be a lot easier to debug. The reason its not working is that all gtk related stuff must happen in the gtk thread, so do all widget method calls like this: gobject.idle_add(widget.method_name). So to hide the password window: gobject.idle_add(self.pwdWindow.hide)

You'll have to import gobject first of course (You might need to install it first).

EDIT: I don't think that that was your problem, either way I edited your program a lot, here is the modified code.
