after change my password using a character * i was unable to login in graphic mode, but in terminal it works ok, i change to a password without * and it works fine in all, graphic and terminal.

[Tiago]

I'm using ubuntu 15.10 and recently change my password it works ok, but after reboot my machine i can't login anymore using the graphic interface, but when i enter the command line mode i can login normally. I make sure that the problem was the password changed instaling ubuntu in a virtual machine and trying the same thing, i realize that when i use the * character in my password this error occurs. Once occurred the first time i try to change the password and login again in graphic mode but it doesn't work, only reinstalling the system.
