Password not working

[stevef]

Unless you get an error message actually saying the password is incorrect, it may not be a password problem.  It may be there is a problem starting the GUI up.  If this is the case, then resetting the password is not what is needed.

To test this when you get to the GUI log on don't use it but press the three keys 'Ctrl' 'Alt' 'F3' at the same time.

This should give a non GUI login.  Enter the usual username (will be echoed) and the password (won't be echoed).

If the login credentials work you will be shown some information and get a terminal prompt.  This will test your name/password without involving the GUI and if ok more diagnostics can be tried.  Typing

Code:

poweroff

followed by return should shut the machine down.

If the credentials don't work, then the system will say 'Login incorrect' and allow you to try again.  When you've tried every possible combination, pressing the power button should shut the machine down.  If this is the case, then you need to reset the password or re-install.
