I have been using the Laptop that I reinstalled the 12.04.3 LTS and then did a live upgrade to 14.04 via the termial and have not had a recurrence of the lock-out state since. I have had one irritation that it sometimes starts with the English (US) keyboard layout instead of the English (UK) that it indicates is selected, this doesn't happen every time and is just an irritation and fixed by clicking the En1 English (UK) icon (the icon on the panel doesn't change and shows En1 every time at boot). I put the lock-out state problem as a possible corruption of the USB I had used to do the install originally though the Desktop I upgraded first with the same USB hasn't shown either problem. John

For as long as I did not log out of the GUI everything was working great. After rebooting, any attempt to login resulted in a flash and an immediate "invalid username/password" response. I have tried my admin account, guest, as well as creating a new account. All accounts worked fine via terminal (CTRL + ALT + F) login. Any help greatly appreciated !
