Comment 13 for bug 862127

Hi,

I can confirm that I am affected by this bug too.

My lightdm.conf says this:
[SeatDefaults]
user-session=gnome-shell
autologin-user=matthew
autologin-user-timeout=0
greeter-session=unity-greeter

But when I log in, /var/log/lightdm/lightdm.log states:

As you can see, there is some confusion somewhere and it's getting the wrong session type from somewhere. I know I can work around it by changing the ubuntu session type so that it loads gnome-shell, but that might break something in the future. Could someone please look at this?
