Comment 9 for bug 862127

I have a me to on this one. The user that fail was upgraded from a 10.10 release to 11.10. Always end up in unity. a newly created account is able to select session.

Is there some way to debug this. Is there some shell script that I can put debug prinouts in.

What command do the lightdm actually run for the different sessions ?? I have no idea of where to look . Is this a fallback effect in that gnome 3 is started fail on something and we fall back to unity or is unity actually started from lightdm even when a different session was selected.
