I figured out what my problem was, and since I haven't seen any solutions anywhere else, hopefully this will be of some use to the next person. In my case it turned out to be the Nvidia driver, which installed its modules under /lib/modules/4.8.0-32-generic. When I upgraded to 4.8.0-34, it couldn't find the drivers. See https://ubuntuforums.org/showthread.php?t=2349132 for more information.
Of course this doesn't explain why it was looking for pam_kwallet.so, which I suspect is a separate issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1511824 Title: Can't login as ordinary user with lightdm To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1511824/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
