[Bug 1667719] [NEW] lightdm-gtk-greeter/lightdm does not honor default session setting for a never logged in user

 

Public bug reported:

This problem applies to Ubuntu-MATE setups using out-of-the-box lightdm
and lightdm-gtk-greeter settings.


To duplicate this bug:

Create a new installation of Ubuntu-MATE.  Create two users (user1 and
user2).

Install a second windows manager (such as openbox)

Have user1 log in using the openbox windows manager and log out.

Have user2 log in. (Note: user2 is a user who as never logged into
machine and has no record of last session used.)

The expected outcome is that user2 will use the default session: MATE, but the outcome is that
user2 will be logged into an openbox session.

lightdm --show-config shows that the default is set to mate:

user1@tester:~$ lightdm --show-config

C  guest-wrapper=/usr/lib/lightdm/lightdm-guest-session
