*** This bug is a security vulnerability ***

You have been subscribed to a public security bug:

On ubuntu 10.04, I choose System > Disconnect > Swich User,
then at the login screen I click Ctrl+Alt+F4 to get a command line over a black screen. the problem: clicking Alt+F7 redirect back to my password 'protected' desktop WITHOUT entering password!

How is it possible and how can I fix it?

Description:	Ubuntu 10.04.3 LTS
Release:	10.04

apt-cache policy login
login:
  Installed: 1:4.1.4.2-1ubuntu2
  Candidate: 1:4.1.4.2-1ubuntu2.2

I expect to go back to the login screen, NOT skipping the password. the
whole idea of a password is to protect the data...

p.s
I can't use "lock screen" because it aventualy freeze my desktop, & the only release is the "reset" button.
