lock screen doesnt work

[Jorge]

The lock screen on Ubuntu 14.04.1 LTS is not working for some reason, .it wants to lock...however the screen just bounces...would appreciate any insight here...thanks... I believe the package for the lockscreen is gnome-screensaver

I expected the screen to lock.
Instead the screen just bounces and doesn't lock. this happened after i updated to the new version of ubuntu.

here is a video of it not locking: http://youtu.be/RCCepVCQ0Zo

Here is the auth.log for when I tried to lock the screen

It seems that somehow my user got added to the nopasswordlogin group. Removing my user from this group would solve the problem so I solved this by going into the terminal and typing in the command line: sudo gedit /etc/group and deleting my user name from the nopasswdlogin group in the text file and then saving the file again. Now I can lock the screen and the system requests a password on the ubuntu login screen. The screen wouldn't lock before because there was no password with which to lock the screen. The system didn't request a password because the user was in the nopasswordlogin group. Thanks.

Kind Regards
