[Bug 1506771] Re: 'Unable to create session' when logging in to a newly created user


Can you get a /var/log/lightdm/lightdm.log after this occurs? The log
attached here seems to show a successful login (i.e. your existing
user). It does sound like the configuration has chosen an invalid
session and so LightDM returns you to the greeter.

  'Unable to create session' when logging in to a newly created user

Status in lightdm package in Ubuntu:

Bug description:
  Similar but not the same as 1056833.

  After creating a new user I was unable to login to her id from
  lightdm. I could login on a text console and then run startx.

  I think the problem is that /var/lib/AccountService/user/$user had
  Xsession=ubuntu instead of xfce. I do not have any Unity code on my

  There is no option in the create-user dialogue to select a session
  type, not in the lightdm login screen.

  I will do some more testing and report back when I have finished this
  bug report.
