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

To this:

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.

  1. I strongly advise you not to fiddle around with files that are so relevant to your OS. They belong to root and are read-only for a reason.

  2. If you want to skip the login-screen (aka Unity-Greeter), go to the "users" aerea of the system settings and edit your account by switching on "automatic login" (may be labelled slightly different, I'm using the German version of 13.04).

Manually editing configuration files is one of the normal ways to adjust settings on most Unix-like systems, including Ubuntu. This problem happens primarily due to a bug. –  Eliah Kagan Jul 22 '13 at 6:34

see https://bugs.launchpad.net/ubuntu/+bug/1173834

Setting "Show desktop icons" ON fixes the problem for me.

You can access this configuration using the "Ubuntu Tweak" utility in 'Tweaks->Desktop Icons'.

The master bug for this is now bug #1115886. –  Eliah Kagan Jul 22 '13 at 6:35
