What else do you expect to start? Something like gnome-session? Check the start on conditions for gnome-session job, and check the xsession job. A useful thing would be output of the running jobs / job summary. The upstart user session file should be somewhere in /run/user/$ID/upstart/sessions/$PID.session Cat that file, export the UPSTART_SESSION variable into your terminal (e.g. on a tty1 login) And then run: $ initctl list And $ initctl2dot to generate a graph of things that are starting. Compare that with working utopic install vs non-working vivid install. If one renames a session, it's session file-name should also be changed, I think.
