If you are running Ubuntu in VirtualBox or other virtualization platform, disabling all the animations improves the response of the OS to certain extent.
Starting with Ubuntu 12.10,
MyUnity integration with the System Settings (as was the case in 12.04) has been removed. In 12.10 and above, which includes 13.04, 13.10 and 14.04,
Compiz settings manager can be used to disable the required animations.
- Step 2: Disable Animations345
- Start the application (from the Unity Dash)
- Traverse to Unity plugin -> Experimental (tab)
- Disable the animations as required.
