After further investigation I found out what my lightdm.conf in /etc/lightdm/ said: [SeatDefaults] autologin-user=

And users.conf: # # User accounts configuration # # NOTE: If you have AccountsService installed on your system, then LightDM will # use this instead and these settings will be ignored # # minimum-uid = Minimum UID required to be shown in greeter # hidden-users = Users that are not shown to the user # hidden-shells = Shells that indicate a user cannot login # [UserList] minimum-uid=500 hidden-users=nobody nobody4 noaccess hidden-shells=/bin/false /usr/sbin/nologin

And lightdm-gtk-greeter-ubuntu.conf: # # background = Background file to use, either an image path or a color (e.g. #772953) # theme-name = GTK+ theme to use # icon-theme-name = Icon theme to use # font-name = Font to use # xft-antialias = Whether to antialias Xft fonts (true or false) # xft-dpi = Resolution for Xft in dots per inch (e.g. 96) # xft-hintstyle = What degree of hinting to use (none, slight, medium, or hintfull) # xft-rgba = Type of subpixel antialiasing (none, rgb, bgr, vrgb or vbgr) # indicators = semi-colon ";" separated list of allowed indicator modules. Built-in indicators include "~a11y", "~language", "~session", "~power". Unity indicators can be represented by short name (e.g. "sound", "power"), service file name, or absolute path # show-clock (true or false) # clock-format = strftime-format string, e.g. %H:%M # keyboard = command to launch on-screen keyboard # position = main window position: x y # default-user-image = Image used as default user icon, path or #icon-name # screensaver-timeout = Timeout (in seconds) until the screen blanks when the greeter is called as lockscreen # [greeter] background=/usr/share/backgrounds/warty-final-ubuntu.png theme-name=Ambiance icon-theme-name=LoginIcons font-name=Ubuntu 11 xft-antialias=true xft-dpi=96 xft-hintstyle=slight xft-rgba=rgb indicators=~language;~session;~power
