Hmm, reading the duplicates, it seems it's a Lenovo notebook + systemd + lightdm combined problem, and does not occur too much if all of the three conditions do not meet? For me, it's true, all of them, and I have the problem at least ...

Choosing running in default mode causes to boot splash to be shown forever. if I choose exit to console, log in then service stop then start for lightdm, it works then though. Maybe is not Xserver bug, but the new init system (systemd) race condition of starting things, or such?
