I just reversed the changes in recovery mode, and that fixed it.

From <A HREF="http://ubuntuforums.org/archive/index.php/t-12777.html">http://ubuntuforums.org/archive/index.php/t-12777.html</A> [2] Have a word with PAM! PAM is the authentication model employed in Ubuntu. The first thing to do is to edit the PAM file that specifies how authentication should work with GDM. Open the file: $ sudo nano /etc/pam.d/gdm Add lines that specify a password is not required for the users who are listed in a file that you are going to make later on. The new line in the file example comes between the #start and #end comments, all the other lines were there anyway and remain untouched: ---------------------- #%PAM-1.0 auth requisite pam_nologin.so auth required pam_env.so # the line below has been added specifically to allow selected users to log in via GDM without a password # start auth sufficient pam_listfile.so item=user sense=allow file=/etc/X11/gdm/nopassusers.txt onerr=fail # end @include common-auth @include common-account session required pam_limits.so @include common-session @include common-password ---------------------- [3] Tell PAM who to let in without a pass Go to this following location: /etc/X11/gdm/ Make a new text file there called nopassusers.txt In this file, list the usernames of the users who can log in without entering a password. Put each user on a new line. OK - that should be it. Like I say, I know this works but have no idea whether it is sensible. Please if you have knowledge contribute to making this a better howto!
