this hit me on a new install of kubuntu 14.10 and its subsequent upgrades. i used the workaround of installing systemd-sysv as others have done, but at that point my graphical desktop (KDE) still would not start. i installed midnight commander to go look at the Xsession errors in my home folder, and i cant recall the full process name but a dbus process kept dying and respawning, and then startkde main process was killed. i attempted 'startkde' at the login prompt and it said there was no startkde command, that i could install it with apt-get kde-workspace-bin, which i did, and it suggested plasma-scriptengines, so while i was at it i got that too. rebooted and there was my KDE. so i reinstalled upstart and ureadahead, which i saw being removed when i did the systemd-sysv install, rebooted again with fingers crossed, and here i am, not saying it 'fixed' anything but it at least gave me back a working system.
