I lost the password to my old laptop, and after reading, I found out how to change it using the text interface.
I successfully changed my password to my root user, but now instead of telling me "Incorrect password" it just blinks the screen black and returns me to the login prompt with no message. I know the password is correct.
I've seen many other questions with this problem, but nobody's solutions have helped so far. I've used the text interface to upgrade to the latest version. I've tried removing Xauthority, (it was not found).
I can login to the root account just fine through the non-graphic interface of course, but I just can't seem to figure out what's wrong with the graphic login.
I am a complete rookie when it comes to Linux/Ubuntu, so keep that in mind. Thanks in advance for any advice you can offer.
