Fine, I did not know. Will look at the blueprints for jaunty+1. What I 
see from that page is the following:

1) Upstream implemented the change. That must have good reasons on their 
  side, and indeed lowers any argument against it.

2) However, nobody cared in the discussion about the problem of fake 
login screens. There is a sentence saying that "nobody needs to kill X 
on the mac" but how many computer labs with osx did you see in your 
life? And perhaps they even have a shortcut to safely get back to the 
login screen! So the argument would be incorrect. Surely the workgroup 
oriented windows versions (2k3 or something, it's a long time since I 
was a slave of microsoft slaves...) have one.

3) In my opinion, it is a small change, and as it may turn to be a 
security problem in computer labs, we are still in time to discuss this 
aspect, and we should.

4) I wonder where the proposal of keeping the button pressed for some 
seconds, or pressing it twice, ended. That would have been a damn good 

5) I still see no good reason for this change except that it's 
"relatively easy to trigger this by mistake". I never did that and I 
have been using linux for 12 years. I even used rm by mistake when 
drunk. Yep, I was young then :)

Can someone tell me how will I protect myself from fake login screens in 
  multi-user ubuntu setups? Even my office machine is multi-user!
