How to remove unity 2d workspace animation?

Unity 2d's workspace animation runs very slowly on my old graphics card. How do you disable them?

Solution 1:

You can set transitionDuration = 0 in the file /usr/share/unity-2d/spreed/utils.js.

Solution 2:

There is no simple way to disable the workspace switcher. It requires changes in the code of Unity 2D.

Solution 3:

I'm running Ubuntu Precise, and the following did it for me:

• Run "CompizConfig Settings Manager" (not sure if it's installed by default)
• Select "Desktop Wall" under Desktop
• Disable "Show Viewport Switcher Preview"
• Select the "Viewport Switching" tab
• Set "Wall Sliding Duration" to zero

Now when switching desktops via the keyboard, I don't get any animations.
