[Crack] Linux Mint Logon Screen HELP! [SOLVED]

[codder_227]

Hey there!

I need help cracking this Logon on Linux Mint. I installed Mint a few days ago and modified it for myself, at all, it was a lot of work. Now, an hour ago, I booted it up and it shows me a completely other logon screen than the standard of Linux Mint:

(My hard drive is encrypted, btw.)

Now, when i wanted to login, it says "username or Password is invailed."

Logical, i thought. "You tipped in the wrong Password".
So I retried it, 10 times.
But it still gives me the same error. (And I didn't forgot the password and my username, I still now it)
For me, there's only chance why I fail every time when I want to logon: The new Login screen.
I modified after I installed Mint, because the standard login screen was awful to me.
So I tried it with a live disk to recover my hard drive. But it failed, because my hard drive is encrypted.

I dont wont to reinstall Mint, because if so I have to install the hole software and mods again, and thats pretty shitty, because it will take me hours.

Do you know how I bypass this logon screen or recover the hard drive?
Or get to the normal logon screen back? (Or viewing my old username  )

(Remember, I still KNOW the PASSWORD!! I'm not quite sure with the username)

Ehh, and btw, when I try to login with root, the error comes:

"The admin is not allowed to login from this login"

Switch to tty console and try to login there and if you are able to login, undo what ever you did to the login screen.

ALT+CTRL+F might have been key combo in mint to switch tty.

Thanks, worked with ctrl + alt + F1 

logged in with root and worked fine

Were none of the options in the "Login Themes" section worthy?

I didn't like the original one, but can't remember what I changed it to.

In case of losing root pwd:
Edit grub right after boot with e and append this to your kernel params:
init=/bin/bash

Resume boot.

You will drop in a root shell , from there you must first remount the disk so you can write to it.
mount -o remount /
then do:
passwd

Set a new password.
