[Bug 1059137] Re: Cannot login after un upgrade from 12.04 to 12.10 (ubuntu-2d)

[Dave Gilbert]

Marked as High, not being able to log in after upgrade seems bad.
(Although this might be a greeter bug rather than lightdm itself?).

We had a couple of people on #ubuntu+1 yesterday hitting this.

One way to distinguish this from a post-login crash is that if the users delete their .xsession-errors, and then try logging in again
the .xsession-errors isn't recreated.

I think there needs to be some logic along the line of:
  If the last session no longer exists then select the 1st available session type.

The people who were talking about this on +1 yesterday didn't see the icon to click on to select the other session (I'm not sure
if this was because there was only one installed session, or because the icon is normally an icon representing the currently selected session, and since that doesn't exist it doesn't have anything to show).

** Changed in: lightdm (Ubuntu)
   Importance: Undecided => High

  Cannot login after un upgrade from 12.04 to 12.10 (ubuntu-2d)

  Confirmed

  Confirmed

Bug description:
  After an upgrade from ubuntu 12.04 to 12.10, I was no more able to login with my usual account.
  Lightdm failed to load x session.
  After a long search, I understood that the problem was coming from ubuntu-2d xsession.
  My user account was configured to use unbuntu-2d when i was in ubuntu 12.04.
  But as this xsession has been removed in ubuntu 12.10, lightdm failed to load  it.

  I managed to fix my problem doing following steps :
   - edit my user file with gedit in this folder :
  /var/lib/AccountsService/users
   - replace "XSession=ubuntu-2d" by "XSession=ubuntu"
   - reboot ubuntu for the file modification to be taken in account.

  In my opinion, this fix should be applied automatically for all users using ubuntu-2d and upgrading their distribution.
