To enable autologin you need to change some configuration options. First, in your terminal, run:
Code:
nano /etc/lightdm/lightdm.conf
Remove the tabs in front of the following lines:
Code:
pam-autologin-service = PAM service to use for autologin
autologin-user=root
autologin-user-timeout=0
Make sure the autologin part looks as it does in the screenshot below.

Save and exit with Control X, then type:
Code:
nano /etc/pam.d/lightdm-autologin
And you'll need to change this, starting on line 11:
Code:
# Allow access without authentication
auth required pam_succeed_if.so user != root quiet_success
auth required pam_permit.so
To this:
Code:
# Allow access without authentication
###auth required pam_succeed_if.so user != root quiet_success
auth required pam_permit.so
Save and close nano. You should now be configured for autologin. Reboot to see if the autologin feature works. It works for me.
