Hy Luke,

The LightDM replacement to Gdm is very interesting me too. How can 
possible doing this replacement for an Oneiric installed system if the 
purpose is working default the a11y support with screen reader in GDM?
My friend sees following error when he trying replace LightDm to Gdm and 
try setting A11y properties with Gdm in terminal, he using following 
command:
root at ubuntu:/# sudo -u gdm gsettings set 
org.gnome.desktop.a11y.applications screen-reader-enabled true

** (process:4488): WARNING **: Command line `dbus-launch 
--autolaunch=20fabca28cb849c3142b381e02746da0 --binary-syntax 
--close-stderr' exited with non-zero exit status 1: No protocol 
specified\nAutolaunch error: X11 initialization failed.\n

** (process:4488): WARNING **: Command line `dbus-launch

root at ubuntu:/#
He tryed using this command an installed Oneiric system.

Possible doing this replacement by default a custom live CD if I would 
like automatic login working too? If I remember right, when I looked 
this with alpha3 based live CD, GDM wont start automaticaly with live 
CD, and I not tryed this replacement now.

I see an another interesting issue with Oneiric and Unity related:
General, I using Oneiric with Gnome Fallback session, but I would like 
trying Unity 2D after I read Guis letter. Because I am not have sighted 
assistance to change session in LightDm, I edited the 
/etc/lightdm/lightdm.conf file:
I uncommented following line:
greeter-session=unity-greeter
And modify following line:
user-session=gnome-fallback
I simple replaced with gnome-fallback session to ubuntu-2d session, and 
restarted lightdm login manager with service lightdm restart command. My 
system are I configured for automatic login, and Unity 2D wonderful started.

I tested little with Unity, and final would like switch back with 
gnome-fallback session. So I again modify /etc/lightdm/lightdm.conf 
fileto I change back the session... :-(:-(
After I restarted LightDm, I very surprised, because simple owerwritten 
or deleted my custom keybindings, with I defined in GNOME Control Center 
the Keyboard pane when I used GNOME Fallback session. For example, not 
possible to pop up panel menue with ALT+F1 key combination, not possible 
to access Run dialog, etc.
Why happened this? Unity stores own key combinations equals place for 
example with GNOME3 fallback session (.config/dconf/user binary 
gsettings file)?
Possible fix this with next release? Have an useful workaround to 
prewent this problem if an user would like using not only Unity 
dependent sessions and already customized for example GNOME3 fallback 
session related keybindings?
