Auto Login

  1. Edit as superuser the lightdm configuration file: 
    gksu leafpad /etc/ligtdm/lightdm.conf
  2. Immediately under [SeatDefaults] add the following lines: 
    autologin-guest=false
autologin-user=YourUserNameHere
autologin-user-timeout=0
autologin-session=lightdm-autologin

    So for Xubuntu, lightdm.conf should read something like this:

    [SeatDefaults]
autologin-guest=false
autologin-user=YouUserNameHere
autologin-user-timeout=0
autologin-session=lightdm-autologin
user-session=xubuntu
greeter-session=lightdm-gtk-greeter
  3. Reboot.
