Although systemd has it's journalctl facility, there are still some info in /var/log files. It's a pita via a console, but if you can access the filesystem via ubuntu see if there's anything. Check /var/log/installer and see if the install left any messages about not finishing.
nothing suspicious in /var/log/installer, in status file all packages have "Status: install ok" and then "installed" or "unpacked". neither did I spot anything in hardware-summary and Xorg.0.log (though I don't know how something wrong should look like).
Then in deamon.log I found a number of entries about lightdm failure:
