I recently upgraded my ubuntu 11.04 to 11.10, but while playing around trying to restore the GNOME classic (I really don't like the unity), I screwed something up. Ubuntu did not came back after restarting... I was stuck.
So I burned an installation CD and reinstalled Ubuntu (upgrade from 11.10 to 11.10) so the data was saved. However, I used a different username on installation by mistake, and now I've got two home folders:
The old_user is not registered as a user (it's not listed in the LightDM login screen), and I really just need one user, with my old data and configuration.
So: is there a quick way to fix it? As in, get my old_user to be the only user with all my settings back?
