Sorry to hear that, Abby - your installation seems to be in a bad shape. You probably need some support on how to fix your Ubuntu installation, and since this is a bug report, it's not the right place for doing that. We haven't even confirmed yet that there is a bug.
I would suggest that you seek help at e.g. http://askubuntu.com/ -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1366209 Title: Returned to the greeter screen when logging in.
