Lock screen appears after login

Question

Suddenly, I'm unable to login to Ubuntu. When I login. I get to this lock screen:-

enter image description here

This is copied from google. What I get is a faded version of this prompt. The only thing I did was a visudo to give root permissions to my user and an apt-get install lxde.

I was able to use LXDE and all other environments until I restarted.

@the_Seppi I can't type anything there, its kinda' faded and I can't type. Also, when logged in I can lock the screen from Gnome Panel which brings out a brighter version of the prompt where I can type but when I click on Unlock, it gets back to the previous state. — Sharad Gautam, May 26 '15 at 12:45

Try the following steps,

press CTRL + ALT + F1

Run the command ls -lah

If you see the following line(or something very similar) in the output continue with the steps below.

-rw------- 1 root root 51 May 23 21:37 .Xauthority

run the command

chown username:username .Xauthority

press ALT + F7 and try to login to your system again.

I had a similar problem and this worked for me. Hope it helps.

That didnt work, I was already the owner of .Xauthority, however I don't know why but doing a chown on .dbus solved the issue. – Sharad Gautam May 26 '15 at 13:27
