When I log in my Ubuntu 13.04 account, my login screen still shows up as my desktop background, making my computer slow. Recently, I made some changes when I log in, such as removing both "Guest Login" and "Remote Login." I used the following code:
sudo gedit /etc/lightdm/lightdm.conf
And changed my default login information:
user-session=ubuntu greeter-session=unity-greeter allow-guest=false greeter-show-remote-login=false
I feel like this was the source of the problem so I tried to delete the added lines but the file was "read only." Is there anyway I can edit the file to fix my problem?
Also, is there anything else I can do so my desktop can return back to normal without the login screen showing? I just recently downloaded Ubuntu 13.04 a couple of days ago so I'm only a beginner.
