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 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1059137 Title: Cannot login after un upgrade from 12.04 to 12.10 (ubuntu-2d) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1059137/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
