can't log in graphically after editing /etc/shadow


hi everyone,
i saw a tutorial in a book about breaking password in linux, it was mostly the same as its in here, it just needed to boot via a live cd, then mount the / partition, after that delete the password in /etc/shadow. well i tried it on my machine, it did worked. but i could only get inside computer via terminal(crtl+alt+Fx) not graphically. does anybody know why?

The GDM has an option to not allow users with empty passwords. Is this what you've done? Are you logging in to the terminal with no password?

You really should not use accounts with no password.

I would login to the terminal and set a new password with the passwd command.

So yeah, you removed the password from your account, the the GDM setting to disallow empty passwords was set (which it is by default.) Do you necessarily want no password for your account? Because another setting you can do through the GDM is autologin for a particular user.

If you do want an empty password, I'd at least recommend that you disable remote logins for that user. (Of course you are entitled to setup your system however you'd like)

Well, if you have root access, you can reset the password of any account.

What you did is effective if you forget your root password.
