Green User Dumb Q ALERT!! Cannot exit Command line at start up!!!

The story goes like this--- I created a new user log in for my mom ,she was getting used to the UBUNTU operating system, pushed some combination of CTRL-something and restarted the computer in command line that I cannot exit out of. I have tried ctrl-alt-f7 and every combination I can find and nothing works. I even tried -- switching users back to myself, rebooting, etc.. Every time it restarts it goes back to command line and says

branden@branden-vgn-cr131e:/home/debrastansberry$

please give me some magic to get my laptop back!!!!!

Thank you so much in advance. Even though I know you think I'm a dumbass.

Branden

I don't even know if what I'm asking for makes sense! I have really enjoyed linux for the past 3 years and this is the first problem I've had. Please help!

what permissions did she have?

I gave her the least possible

Here is a photo of what my screen looks like.

What happens with:

Code:

---

sudo start lightdm

---

start: job is already running: lightdm

Oops. Made my suggestion before I saw your latest post.

1. Do you recall what you did?
2. Try typing exit. (Likely won't work but worth a try.)
3. Do:

Code:

---

sudo update-grub

---

4. Reboot

If this doesn't work, let's see how grub is configured:

Code:

---

nano /etc/default/grub

---

It says GNU nano 2.2.6 and then a menu below. How do I know how it's configured? Sorry for being ignorant. I'm over my head.
