Title:
Unity extremely slow after installing/upgrading to Ubuntu 12.04

Bug description:
Preface:
-----------
This bug reads simmilar to Bug #982710 but seems to be independend from the
Nvidia driver due the bug occours after upgrading unity from version 5.8.0 to
5.10.0 -- without touching the Nvidia driver (currently using 295.40) at all.
Also installing older versions (295.33, 295.20) of the Nvidia driver after
upgrading unity will not fix the problem.
Description:
-----------------
After installing Ubuntu 12.04 LTS (final release), Unity is dead slow:
Switching between virtual desktops or application windows takes several
seconds, moving windows causes "hanging" for up to several seconds, system load
(top) is never below 0.5 (even when unused), most time far above 1.0. Ubuntu is
using by default the proprietary Nvidia driver (package nvidia-current) version
295.40.
With a fresh installed Ubuntu 12.04 LTS Beta-2, Unity is smooth and
fast, allthough it's using the same Nvidia driver 295.40 (package
nvidia-current) by default. It's still fast and smooth after
installing all pending updates _except_ the packages unity, unity-
common, unity-services, libnux-2.0, libnux-2.0-common.
After updating unity, unity-common, unity-services from version 5.8.0
to 5.10.0 and libnux-2.0, libnux-2.0-common from version 2.8.0 to
2.10.0, the system is dead slow again like a fresh installed Ubuntu
12.04 LTS (final release).
So the problem must be one of these five packages: unity, unity-
common, unity-services, libnux-2.0, libnux-2.0-common
Due to the dependencies, I was unable to update these five package for
package to find out the single one causing the problem.
However, there seems to be some Nvidia relation after all: Installing
Ubuntu 12.04 LTS (final) on my netbook with Intel graphics, Unity
5.10.0 doesn't cause any problem.
Technical Details:
------------------
To prevent the five packes from updating, I set unity, unity-common,
unity-services to "hold" using:
echo "unity hold
unity-common hold
unity-services hold" | dpkg --set-selections
This prevented also the libraries libnux-2.0 and libnux-2.0-common
from updating.
