How do I bypass The TTY login on ubuntu 12.04 lts and what is it?

Question

I have Ubuntu 12.04 LTS and I want to know what is a tty login. I was opening my laptop and the screen went black and was written "Ubuntu 12.04 LTS harshira-HP-ProBook-445-G1 tty1". Now it does not go through this. What is a tty? And how do I bypass the tty login so that I can use my PC in graphical mode?

Solution

Simplest solution first, have you tried Ctrl+Alt+F7 (Not F8)? If this doesn't work, try this:

1. Login from the command line using your username and password.

2. Try starting the lightdm service.

   sudo service lightdm restart
   

Otherwise, if your computer displays a message there's something wrong with the swap, you could try doing sudo swapoff -a and repeat the above steps. If they work now, something probably is wring with your swap.

That's all I have now. If these don't work, try posting some more info.

Have you tried using Ctrl+Alt+F7 when you get the black screen? What happens if you have tried?

Seeing the command line interface like this usually means that the graphical one has failed (not that you're ending up in the wrong place). The answer given will work if X is running but I'd be surprised if that applies here.

X mode is also not working. it said: mountall: swap is terminated with status 255 like i said below

He'll probably have to export his DISPLAY variable too.
