lock screen not working

Asked by 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
