00:11 < d_ed> hey, I /think/ (if I remember correctly) it's a missing package of sorts, and installing unity-greeter "happens" to fix it

00:12 < d_ed> the guest-setup script does some gconf calls to disable the screensaver and such, and it's not "if'd" out.

[+3.94s] DEBUG: Can't autologin guest, no guest account

When we run the guest account creation script on it's own (/usr/sbin/guest-account add):
Adding system user `guest-xNlkcz' (UID 117) ...
Adding new group `guest-xNlkcz' (GID 127) ...

bash: line 1: gconftool-2: command not found

 1) This a packaging bug in lightdm, it should depend on gconftool-2 if it uses it.
 2) wrong anyway. The lightDM guest-account-add script should not be doing Gnome specific things.
 3) we need a way to add the same, but KDE specific stuff, namely:
     Disable nepomuk (initial table creation takes a long time, and all data is discarded anyway, Vishesh agreed on this)
     Disable the screen lock (as if it does lock, the user is locked out completely)
     Disable jockey, software update et-al that need root access.

I'm pretty sure they'll be (equally) upset if we just add KDE code into this script, so we need to talk to upstream about a good universal way to do this, maybe loading a specific script based on the session name.

I was given the impression this is now fixed.

Is this now confirmed fixed?
