Comment 29 for bug 678421

Hmm, as 1.13.0-0ubuntu1 just showed up in vivid, it broke my login in the follow way. Note that I always try devel channel updates in a VM with a snapshotted disk so I'm able to revert and do some further investigating. Looking at the dist-upgrade packages, I suspect the lightdm changes are affecting me, but I'm going to continue to investigate.

So, when I log in, I do get several warnings in a dialog. Most are because I use `source` instead of `.` to source other shell files. What shell is lightdm using these days? Still, even with the warnings, I can log in just fine.

Anyway, when I change them all to `.` I still get one warning about my use of shopt, but I'll just ignore that for now. However, logins are now completely broken. I see the screen blank and then I'm thrown back to the login screen. ~/.xsession-errors is empty and I can find no other log file either in $HOME or /var/log that contains any information about what's going wrong.

I'm going to pin lightdm and dist-upgrade everything else just to verify that the lightdm update is causing my problems. How can I debug the login crash after I fix my login scripts?
