Thanks for your help It looks like problem was with dbus - there were some messages like "could not connect to system bus". I manually remove files in /var/run/dbus and restart dbus as "dbus-daemon --system" and lightdm started after it.

Before the login screen Ubuntu prints out some state messages. The last one is "Checking battery state" (mine it is not a portable PC) I have to press Alt+F1, I logged in and wrote "startx". Gnome3 says "Failed to load session "gnome-fallback"" (my pc doesn't support neither Gnome-shell nor Unity3D) and pressing the only button Log Out terminal compares again. Is it possible to rollback last upgrade of Lightdm?
