Bug Description

LightDM doesn't automatically use GNOME Shell as guest session after uninstall of Unity. There is not even a graphical user interface for setting the default session.

When a user removed Unity, but did not change any setting manually and tries to start a guest session, the user will see just a plain background image with no interface at all. Only Ctrl+Alt+Delete allows to logout.

As a workaround you have to manually edit "/etc/lightdm/lightdm.conf" and change "user-session=ubuntu" to "user-session=gnome-shell".

Thank you for your bug report, that's not really a bug and not specific to the guest session, the same would probably happen for new users, if you remove the default session you should probably tweak your config to point to another session, why would lightdm pick gnome-shell over gnome classic or KDE or XFCE?

It may should ask the user about what session to use but it should not try to start an non-existing session.

the idea is that it should kick in failsafe debug mode when that happens to let you fix your config

(btw the other bug you report that your marked privated can't be read by triagers now that it's private so it's likely to not get any further reply)

In newer versions of lightdm there is a guest-session option in the config. Otherwise you should set your default session to the one you prefer.
