Hi Anatoly - thanks for reporting this issue. Presumably, lightdm started correctly before you noticed this issue? If the process is still running, please do: sudo cat /proc/$(pidof initctl)/stack > /tmp/initctl.stack ... and attach "/tmp/initctl.stack" to this bug. Then, to stop initctl (by forcibly crashing it, which might provide some more clues): sudo kill -ABRT $(pidof initctl) This second command should cause an apport window to pop up.
