Edit /etc/lightdm/lightdm.conf and comment out autologin-user line.
That assumes it is using lightdm. Not certain of that with 16.04 but I

The fact that you have autologin enabled and syslog is not showing anything
obvious means it may well be  a graphics problem after login and not a boot
problem at all.  What graphics card do you have?
