I am running Ubuntu 10.04 on Virtualbox in Windows 7. I gave admin permissions to a new account and deleted my old main Ubuntu user (the one with which I installed ubuntu). I also deleted the home directory for the old admin user. I had set autologin and password less login on the old account. So now whenever the system reboots, it seems to search for the old user home. e.g. I get errors like "Could not find /home//ICEAuthority", "Nautilus could not load desktop" or something like that. I can only work with Ctrl+Alt+f1 now. I think the problwm is because of the auto login. It stills searches for the old account for auto login. How can I disable auto-login or set auto login to the new account?
