I wanted to manually configure the internet settings & decided to seek help from this website. Ubuntu did not allow me to perform step 1 saying,
X: user not authorized to run the X server, aborting
so I logged in as superuser by executing
sudo -s. Then I executed step 1. Suddenly all the tray icons disappeared & the only thing that was being displayed was the wallpaper. I wasn't able to shutdown/restart & chose to shutdown the laptop directly with power button. Upon restart, I had the following problems,
- I am able to login with a guest account.
- I'm unable to login with my user account. Logging in brings me back to the login screen.
I am using ubuntu 13.04. How can I fix this?
