Arvind, this is *not* the same bug.  This bug is a problem with every
lightdm greeter package except the gtk greeter failing to start a desktop
session unless the user manually selects a desktop session.

Perhaps you encountered this bug:

https://bugs.launchpad.net/lightdm/+bug/971891

instead?

Hopefully:

Perhaps htmldevelopers suggestion will help you.

Another thing you can try doing is replacing lightdm with another display
manager like gdm or slim.

If you boot in recovery-mode, select the fsck option, start networking, and
drop to a console you can do:

apt-get update
apt-get install gdm

and select gdm as your default display manager.

It may not look pretty (though you can change the theme to improve that)
but it may work better than lightdm.'

But you should probably look for help in the wiki or forums instead of the
bug tracker.

  lightdm fails to start session unless user selects session

Bug description:
  I install using preseed files, and clobber a bit of /etc to configure
  ubuntu to be suitable for users to login with network credentials.  I
  use pam to make a home directory when users login with network
  credentials.

  On first boot, logging into the VTs works fine but I cannot log into
  the lightdm dislpay manager.  If I type my username and password
  right, I get a "Failed to start session" message and get bounced back
  to the start of the login process.

  If, however, I click one of the session types, e.g. 'ubuntu' or
  'fluxbox', then I can log in.  (I've tried uninstalling fluxbox, this
  doesn't seem to help).  At which point I can login, which I believe
  works until I reboot the machine.  (I will test this shortly).

  If I install the lightdm-gtk-greeter package then I do not encounter
  this bug.  Instead, I am automatically logged into the alphabetically
  first session type (at least, if I've got fluxbox available vs. either
  ubuntu or xfce, that seems to be what I get, if only ubuntu is install
  I get an ubunut session by default so I assume the preference is
  alphabetical).

  It does not seem to matter if I specify a 
  user-session=something
  (I have also tried not setting user-session at all)

  in lightdm.conf (well, I haven't tried it with the gtk-greeter, but it
  doesn't matter with the unity greeter).

  I've tried all of the other lightdm-greeter packages, and lightdm-
  greeter-gtk is the only one that does not suffer from this bug.

  the most relvant message in the logs I can find is:

  DEBUG: Seat: Failed to find session configuration true
  Seat: Can't find session 'true'

  What I would expect to happen is to get some default session; getting
  the alphabetically first session is kind-of/sort-of reasonable.  Total
  failure is not.
