I use pam to make a home directory when users login with network credentials. On first boot, logging into the VTs works fine but I cannot log into the lightdm dislpay manager. If I type my username and password right, I get a "Failed to start session" message and get bounced back to the start of the login process. If, however, I click one of the session types, e.g. 'ubuntu' or 'fluxbox', then I can log in. (I've tried uninstalling fluxbox, this doesn't seem to help). At which point I can login, which I believe works until I reboot the machine. (I will test this shortly). If I install the lightdm-gtk-greeter package then I do not encounter this bug. Instead, I am automatically logged into the alphabetically first session type (at least, if I've got fluxbox available vs. either ubuntu or xfce, that seems to be what I get, if only ubuntu is install I get an ubunut session by default so I assume the preference is alphabetical). It does not seem to matter if I specify a user-session=something (I have also tried not setting user-session at all) in lightdm.conf (well, I haven't tried it with the gtk-greeter, but it doesn't matter with the unity greeter). I've tried all of the other lightdm-greeter packages, and lightdm- greeter-gtk is the only one that does not suffer from this bug. the most relvant message in the logs I can find is: DEBUG: Seat: Failed to find session configuration true Seat: Can't find session 'true' What I would expect to happen is to get some default session; getting the alphabetically first session is kind-of/sort-of reasonable. Total failure is not.
