Ubuntu security problem in the lock screen: I am running Ubuntu 14.04 with all the packages updated. When the screen is locked with password, if I hold ENTER after some seconds the screen freezes and the lock screen crashes. After that I have the computer fully unlocked. You're using gnome-screensaver? Do you want ants? Because that's how you get ants. I told you so, 2004 edition. I told you so, 2005 edition.
