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.

Don't forget to set the packages on hold using "dpkg --set-selections" so they won't be upgraded next time you start the update manager.

I'll assume this as a duplicate of bug 987304 which has a fix that has already been uploaded and is expected to soon be accepted in precise-proposed.

Sorry, no: The packages unity-5.12-0ubuntu1 etc. does not fix this bug. I just upgraded the packages listed above to version 5.12 and Unity is again dead slow. There seems to be no difference to version 5.10.

Obviously, this one and bug 987304 are different.

I'll install unity 5.8.0 again then...

Actually, bug 987304 is a performance regression that was only introduced in Unity 5.10. And it will be fixed in 5.14.

Let's keep this as a duplicate of bug 987304 for now. If it is not resolved in Unity 5.14 (or 5.12-0ubuntu2) then it is not a duplicate of bug 987304. If this issue is still not solved, then please look at bug 1005074 which might be the same issue as this.

summary:

- Unity extremely slow after installing/upgrading to Ubuntu 12.04
+ [regression] Unity extremely slow after upgrading to 5.10 (it's fast
