I've just upgraded from Xubuntu 14.10 to 15.04. After rebooting I was presented with a blank screen. Switching to a terminal I could see that lightdm-gtk-greeter was consuming 100%. After that I switched back to the graphical environment. Then I clicked the left-mouse button at a random position and the normal login screen came up and I could log in.

I added the allow-debugging=true option to lightdm-gtk-greeter.conf and restarted. I attached the resulting x-0-greeter-log.

After that added the option active-monitor=0 as suggested in one of the comments above. This workaround solves the problem for me. After the reboot the login screen comes up immediately.
