I have had this problem before - it is annoying you cannot change the keyboard layout from the greeter screen (afaik). If you know what keyboard layout you started with (to set the password) and which one you changed to you may be able to work out what you need to type on the new layout to generate the password. In my case it was a simple case of swapping one character since the keyboards involved were US English and UK English. If you press <Ctrl><Alt>F5 e.g. at the login screen you get a terminal where you can try typing your password and can see what you are typing. If you can get online on another machine you can lookup the relevant layouts otherwise it is a matter of trial and error. Once in, go into Settings/User Accounts and reset your password using the current keyboard. Also go into Settings/Keyboard and remove any layouts you do not want.

You can try logging in at the terminal to see what error message is given. If it is "incorrect password" then the username/password combination given does not accord with those stored by the computer. If it is not an input issue then I guess the stored credentials may be corrupted but that is unlikely.

Did you change your physical keyboard or just the layout setting?

I only changed the layout, i tried to write the password as a password for the wifi to check if it written right and it was completely right and i copied it and paste it but it still didnt work too
