I still have this issue on 12.04 using the NVIDIA drivers (295.49-0ubuntu0.1) with the following card: VGA compatible controller: NVIDIA Corporation G98M [Quadro NVS 160M] (rev a1).
When I switch the workspace using a keyboard shortcut (e.g. ctrl+alt+left) a short freeze (several seconds) may occur.
On the previous Ubuntu version I did not notice this issue using the open source Nvidia drivers (I still had this issue using the NVIDIA drivers).
