How do I adjust the alt-tab speed?

It ends up that there is a delay of 2ms set in the alt-tab switcher (called the Static Application Switcher) by default.

To change it, use you can use CompizConfig Settings Manager Install ccsm. After you install it, run it via the dash by searching for compiz or just run ccsm from alt-f2:

And then set Popup Window Delay to 0 in the behavior tab.

And crank up the speed:

  1. Requirements: You will need Compiz Config Settings Manager (CCSM).

    sudo apt-get install compizconfig-settings-manager
    

    You may also need the Compiz Plugins too. The compiz plugins were included in compizconfig-settings-manager in earlier versions of Ubuntu

    sudo apt-get install compiz-plugins
    
  2. Enable Static Application Switcher

    CCSM > Window Management > Static Application Switcher > Check the box to enable it.

    2.1 You will be prompted with a "bindings conflict" dialogue. Select Resolve conflicts.

    enter image description here

    2.2 Now you will be prompted with this monstrosity:

    enter image description here

    Select yes to disable any and all conflicts. Which one is yes? The third option, furthest to the right, it will always be the third option furthest to the right.

    You will now get a weird Application Switcher when you Alt+Tab. It will look like you've broken everything. Next we'll configure it.

  3. Go to CCSM > Window Management > Static Application Switcher >

    3.1 Bindings

    CCSM > Window Management > Static Application Switcher > Bindings

    • Ensure the Next window binding is set to Alt+Tab
    • Ensure the Prev window binding is set to Shift+Alt+Tab
    • Ensure the Next window (All windows) binding is set to Control+Primary+Alt+Tab
    • Ensure the Prev window (All windows) binding is set to Shift+Control+Primary+Alt+Tab
    • Ensure all the binding above are disabled in the CCSM Ubuntu Unity Plugin (UUP). The binding for UUP can be found in CCSM > Ubuntu Unity Plugin > Switcher.

    The Static Application Switcher Bindings should like something like this:

    enter image description here

    And the Ubuntu Unity Plugin Bindings should look something like this (notice that the first 4 bindings are disabled, because we're using the static application switcher):

    enter image description here

    3.2 Behaviour

    CCSM > Window Management > Static Application Switcher > Behaviour

    • Speed = 50.0000

    • Timestep = 10.0000

      Timestep is how often the window's direction is recalculated. A high timestep will result in windows that overshoot their position and bounce back, and a low timestep will result in windows that drift slowly and accurately to their position. - http://wiki.compiz.org/Plugins/Scale

    • Popup Window Delay = 0.0000

      enter image description here

    3.3 Appearance

    CCSM > Window Management > Static Application Switcher > Appearance

    • Show icon only = Yes:Checked

      enter image description here

Done! Alt+Tab should be much faster.
