Responsiveness: LightDM in ubuntu 12.04 very slow

I tested lightdm-gtk-greeter instead of unity-greeter. In
/etc/lightdm/lightdm.conf my system now has:
greeter-session=lightdm-gtk-greeter
With this change the slowness is now gone. Therefore this bug seems to
be in unity-greeter.

Please note that if a different greeter theme is used in LightDM, the
lag issue also stops. Unity-Greeter needs to be handled by LightDM as a
.conf file, not through the other stuff 12.04 currently has to control
configuration. Every LightDM greeter I use that is controlled by a .conf
file works

I found the problem causing most, if not all of the mouse problems on
LightDM: The Ambiance and/or Radiance themes. To fix the problem,
install the Ubuntu Tweak PPA ppa:tualatrix/ppa, install Ubuntu Tweak,
and go to Ubuntu TweakTweaksLogin Settings. Change the GTK theme to
Adwaita. If not
is the issue happening only in the greeter? the same theme is used for
the session...

This affects me and is a dealbreaker. Clicking on anything in the
greeter (username, password field, shutdown) takes anywhere between 2
and 30 seconds.

After the upgrade from 11.10 to 12.04, the desktop was painfully slow,
the lightdm process took 100% on a single core. Applying the workaround
from bug #1005642 fixed the problem for me. Still, a very serious issue!

I think I may have found the cause of the problem, or a very similar
one, at least. See bug #1005642
