How can I change the background color of the unity launcher?

  • 772

I really dislike the slight dark-purple tint to the side-launcher bar and shell surrounding the menu after pressing the meta key. How can I set this to another color?

There are configure options available for Unity here but there is no option for this, so I am looking for pointers in the code where this can be set.

    (This is an incomplete answer that needs improvement and investigation, but should provide someone who knows C++ with enough detail to find the real answer)

    By default the Launcher uses a light gray semi-transparent color. When you hit invoke the dash, the entire thing takes on a blurred look based on the averages of your wallpaper colors. I asked Marco Trevisan where this can be modified, but it's in a bunch of places.

    However, for the launcher when it's just sitting there you need to look in Launcher.cpp:

    First grab the code:

    bzr branch lp:unity

    Then look in unity/plugins/unityshell/src/Launcher.cpp for the _background_color variable and adjust accordingly.

  2. My trick (has to be re-done every restart / log in):
    * MyUnity (program) -> Dash -> Blur ON (or, at your own risk: ccsm -> unity plugin -> experimental -> blur -> static)
    * prepare a bitmap (image) of your desired color and desktop size
    * log out
    * don't invoke the dash!
    * open the prepared image in the default viewer, go full screen mode and press the WinKey

    From now on the Dash will be almost the color you wanted to be.
