Try:
Code:
gksu medit /etc/lightdm/lightdm.conf
It will look something like:
Quote:
wadda@glenda:~$ cat /etc/lightdm/lightdm.conf
[SeatDefaults]
autologin-guest=false
autologin-user=wadda
autologin-user-timeout=0
autologin-session=lightdm-autologin
greeter-session=lightdm-gtk-greeter
greeter-setup-script=/usr/bin/numlockx on
user-session=Navigatrix
wadda@glenda:~$
The magic is in
autologin-session=lightdm-autologin, with the proper
autologin-user= <---with the correct username appended here.
Save and reboot. See it that does the trick.
