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.
